Open Coil vs Pocket Sprung Mattresses: What's the Difference?

Open Coil vs Pocket Sprung Mattresses: Which Is Better?

Choosing the right mattress isn't just about finding one that feels comfortable in a showroom—it's about selecting a mattress that provides the right support, comfort and durability for years to come. One of the most common questions buyers ask is whether they should choose an open coil mattress or a pocket sprung mattress.

Although both use springs to support your body, they perform very differently. The way the springs respond to movement, distribute weight and relieve pressure can have a significant impact on your sleep quality, particularly if you experience back pain, share your bed with a partner or have specific comfort preferences.

In this guide, we'll explain the key differences between open coil and pocket sprung mattresses, compare their advantages and disadvantages, and help you decide which option is best for your sleeping position, body weight, budget and long-term comfort. We'll also answer some of the most common questions people ask before buying a new mattress, so you can make an informed decision with confidence.

Whether you're replacing an old mattress or buying your first one, this guide will help you understand which spring system is most likely to give you the restful, supportive sleep you're looking for.

Open Coil vs Pocket Sprung: Which Mattress Should You Choose?

If you're looking for a quick answer, here's a simple comparison to help you decide.

Choose an Open Coil Mattress if you:

• Want a more affordable mattress.
• Need a mattress for a guest bedroom or occasional use.
• Prefer a firmer, traditional feel.
• Are shopping on a tighter budget.

Choose a Pocket Sprung Mattress if you:

• Sleep on your mattress every night.
• Share your bed with a partner and want reduced motion transfer.
• Need better pressure relief for your shoulders, hips or lower back.
• Want a mattress that adapts more closely to your body's shape.
• Are looking for greater durability and long-term value.

For most people, particularly couples and those looking for long-lasting comfort, a pocket sprung mattress is often the better investment. However, a well-made open coil mattress still offers excellent value for guest rooms, children's bedrooms and anyone looking for reliable support at a lower price.

If you're still deciding between different mattress types, our Mattress Buying Guide explains the key factors to consider before making your purchase. If you're looking for enhanced comfort and pressure relief, you may also find our guide to Hybrid Mattresses helpful, as they combine pocket springs with advanced comfort layers for balanced support.

How Do Open Coil and Pocket Sprung Mattresses Work?

Although both mattress types use metal springs as their core support system, the way those springs are constructed makes a significant difference to comfort, support, pressure relief and durability.

Understanding how each spring system works will help you choose the mattress that's best suited to your body, sleeping position and budget.

What Is an Open Coil Mattress?

An open coil mattress (also known as a traditional spring mattress or Bonnell spring mattress) uses a network of hourglass-shaped springs that are connected together by a continuous wire.

Because the springs are linked, they work as one complete unit. When pressure is applied to one area of the mattress, the surrounding springs also move. This creates a firmer, more uniform sleeping surface but means the mattress cannot contour closely to your body's natural curves.

Open coil mattresses are widely chosen because they offer dependable support at an affordable price. They are particularly popular for:

• Guest bedrooms
• Children's bedrooms
• Student accommodation
• First homes
• Budget-conscious shoppers

While they provide good overall support, they generally transfer more movement between sleepers and offer less pressure relief than pocket sprung mattresses.

What Is a Pocket Sprung Mattress?

A pocket sprung mattress contains hundreds—or often thousands—of individual springs, each sewn into its own fabric pocket.

Unlike an open coil system, every spring moves independently. When you lie down, each spring compresses separately to respond to your body's weight and shape. This allows the mattress to contour more precisely around areas such as your shoulders, hips and lower back while helping to keep your spine in better alignment.

Because the springs work independently, movement is less likely to travel across the mattress. If your partner changes position during the night, you're less likely to feel the disturbance.

Pocket sprung mattresses are often recommended for:

• Couples
• Side sleepers
• Combination sleepers
• People with pressure-sensitive joints
• Anyone looking for higher levels of comfort and long-term durability

Many premium mattresses combine pocket springs with comfort layers such as memory foam, latex or responsive foam to create what is known as a hybrid mattress. These mattresses offer the responsive support of individual springs together with enhanced pressure relief and comfort.

Key Construction Differences

Feature	Open Coil	Pocket Sprung
Spring design	Connected springs	Individual springs in fabric pockets
Movement	Entire spring unit moves together	Each spring moves independently
Pressure relief	Moderate	Excellent
Motion transfer	Higher	Low
Body contouring	Limited	Excellent
Support & Durability	Good	Very good to excellent
Typical price	Budget friendly	Mid range to premium

The biggest difference is how the springs respond to your body. Open coil mattresses provide a more traditional, even feel across the whole surface, while pocket sprung mattresses adapt individually to different pressure points for more personalised support and comfort.

Open Coil vs Pocket Sprung Mattresses: Side-by-Side Comparison

Now that you understand how each spring system works, let's compare open coil and pocket sprung mattresses across the factors that matter most when choosing a new bed.

1. Comfort

Pocket sprung mattresses generally provide a higher level of comfort because each spring responds independently to your body's shape. This creates a more personalised sleeping surface that cushions pressure points without sacrificing support.

An open coil mattress offers a firmer, more consistent feel across the entire mattress. While many people find this comfortable, it doesn't adapt to the body's natural curves as effectively.

Winner: Pocket Sprung

2. Support and Spinal Alignment

Both mattress types can provide good support when they are well made. The key difference is how that support is delivered.

Open coil mattresses distribute your weight across a connected spring system, giving a stable and supportive sleeping surface.

Pocket sprung mattresses provide more targeted support because each spring reacts independently. This helps keep your spine in a more natural position while reducing pressure on the shoulders, hips and lower back.

For many people—particularly side sleepers and those with joint discomfort—this individual support leads to better overnight comfort.

Winner: Pocket Sprung

3. Pressure Relief

Pressure relief is especially important if you regularly wake with sore shoulders, aching hips or lower back discomfort.

Because open coil springs move together, pressure tends to spread across the mattress rather than being relieved at individual contact points.

Pocket sprung mattresses contour more closely around your body, helping to reduce pressure where it's needed most. When combined with comfort layers such as memory foam or responsive foam, pressure relief can be even more effective.

Winner: Pocket Sprung

4. Motion Isolation

If you share your bed with a partner, motion transfer can significantly affect your sleep.

With an open coil mattress, movement on one side of the bed is more likely to be felt on the other because the springs are connected.

Pocket sprung mattresses isolate movement far more effectively, as each spring works independently. This helps reduce disturbances if your partner changes position or gets out of bed during the night.

Winner: Pocket Sprung

5. Cooling and Breathability

Both mattress types allow air to circulate through the spring unit, making them generally cooler than solid foam mattresses.

The cooling performance of either mattress will also depend on the comfort fillings and mattress cover. Breathable fillings, cooling fabrics and natural fibres can all improve temperature regulation.

Neither spring system has a major advantage on its own.

Winner: Draw

6. Durability

A mattress is a long-term investment, so durability matters.

Open coil mattresses are designed to provide dependable support, but because the springs are linked together, they can lose their original shape more quickly under regular use.

Pocket sprung mattresses distribute weight more evenly across thousands of independent springs, helping them maintain comfort and support for longer. Premium models with higher spring counts and quality fillings often have the longest lifespan.

Winner: Pocket Sprung

7. Price

Open coil mattresses are typically the more affordable option, making them ideal for shoppers with a tighter budget or for spare bedrooms.

Pocket sprung mattresses usually cost more because they require a more complex manufacturing process and contain individually housed springs. While the initial price is higher, many people find the added comfort and durability offer better long-term value.

Winner: Open Coil (for affordability)

8. Best for Couples

Couples often have different body weights, sleeping positions and movement patterns.

Pocket sprung mattresses adapt independently to each sleeper, reducing motion transfer and providing more personalised support across both sides of the bed.

Open coil mattresses can still be suitable for couples, but they are more likely to transfer movement and may feel less accommodating if both sleepers have different support needs.

Winner: Pocket Sprung

Overall Verdict

Both mattress types have their strengths, but they suit different needs.

Choose an open coil mattress if your priority is affordability, occasional use or a traditional supportive feel. They offer reliable performance and excellent value for guest rooms, children's bedrooms and budget-conscious buyers.

Choose a pocket sprung mattress if you're looking for better pressure relief, reduced partner disturbance, improved body contouring and greater long-term comfort. For most people who sleep on their mattress every night, a quality pocket sprung mattress is usually the better long-term investment.

If you're looking for even greater comfort, many modern hybrid mattresses combine individually pocketed springs with advanced comfort layers to deliver responsive support, excellent pressure relief and enhanced durability.

Who Should Choose an Open Coil Mattress?

An open coil mattress is an excellent choice for many sleepers, particularly if you're looking for reliable support at an affordable price. Although it doesn't contour to the body as closely as a pocket sprung mattress, it still offers a comfortable and supportive sleep surface for the right person.

An open coil mattress may be the best choice if you:

You're Shopping on a Budget

Open coil mattresses are typically the most affordable spring mattresses available. If you're looking for dependable comfort without spending a premium, they offer excellent value for money.

You Need a Mattress for a Guest Bedroom

For occasional use, an open coil mattress provides comfortable support without the higher cost of a premium pocket sprung model. It's an ideal solution for spare rooms and guest accommodation.

You're Furnishing a Child's or Teenager's Bedroom

Children and teenagers often don't require the advanced pressure relief offered by pocket sprung mattresses. A quality open coil mattress provides reliable support while keeping costs manageable as they grow.

You Prefer a Traditional Mattress Feel

Some people simply enjoy the firmer, more even sleeping surface that an open coil mattress provides. If you don't like the feeling of sinking into a mattress, an open coil design may feel more familiar and supportive.

You Need a Mattress for Occasional Use

Holiday homes, rental properties and spare bedrooms can all benefit from an open coil mattress, where affordability and dependable performance are often more important than luxury comfort.

Open Coil Mattress Summary

An open coil mattress is ideal if your priorities are:

• Excellent value for money

• Reliable everyday support

• A traditional firmer feel

• Guest bedrooms and occasional use

• Children's and teenagers' bedrooms

For everyday use by couples or those seeking enhanced comfort and pressure relief, a pocket sprung mattress is often the better long-term choice.

Who Should Choose a Pocket Sprung Mattress?

Pocket sprung mattresses are designed to provide more personalised support by allowing each spring to respond independently to your body's movements. This makes them one of the most popular choices for everyday sleeping.

A pocket sprung mattress may be the right choice if you:

You Share Your Bed with a Partner

Because the springs move independently, movement is less likely to travel across the mattress. This helps minimise sleep disturbance if your partner changes position during the night.

You're a Side Sleeper

Side sleepers place greater pressure on their shoulders and hips. A pocket sprung mattress contours more closely to these areas, helping to improve comfort while maintaining proper spinal alignment.

You Experience Pressure Points

If you regularly wake with sore shoulders, hips or lower back discomfort, the targeted support provided by individual pocket springs can help relieve pressure more effectively than a traditional open coil system.

You Want Long-Term Comfort

Pocket sprung mattresses generally retain their comfort and support for longer than open coil mattresses, making them a worthwhile investment for everyday use.

You Want the Best Overall Sleep Experience

If your budget allows, a quality pocket sprung mattress offers an excellent balance of support, comfort, durability and motion isolation, making it suitable for a wide range of sleepers.

Pocket Sprung Mattress Summary

A pocket sprung mattress is ideal if you:

• Sleep on your mattress every night

• Share your bed with a partner

• Need better pressure relief

• Want reduced motion transfer

• Are looking for long-term durability

• Prefer a mattress that adapts to your body's shape

If you're looking for an even more advanced sleep solution, consider a hybrid mattress, which combines individually pocketed springs with premium comfort layers to deliver enhanced pressure relief, responsive support and improved temperature regulation.

Which Mattress Is Best for Your Sleeping Position and Body Weight?

Your ideal mattress depends on more than just the spring system. Your sleeping position, body weight and personal comfort preferences all influence which type of mattress will provide the best support and help you wake feeling refreshed.

Here's how open coil and pocket sprung mattresses compare for different sleepers.

Side Sleepers

Side sleepers place the greatest pressure on their shoulders and hips. A mattress that contours to these areas can help relieve pressure while keeping the spine properly aligned.

Because each spring works independently, a pocket sprung mattress adapts more closely to the body's natural curves, making it the better choice for most side sleepers.

Best choice: Pocket Sprung

Back Sleepers

Back sleepers need consistent support to maintain the spine's natural curve and prevent the hips from sinking too deeply.

Both open coil and pocket sprung mattresses can provide excellent support, provided you choose the correct firmness. However, pocket sprung mattresses offer more targeted support around the lower back, making them the preferred option for many people.

Best choice: Pocket Sprung (with the correct firmness)

Stomach Sleepers

Sleeping on your stomach requires a mattress that keeps your hips from sinking too far into the sleep surface.

Both mattress types can work well, especially in medium-firm to firm comfort levels. If you prefer a flatter, more supportive feel, an open coil mattress may be perfectly suitable.

Best choice: Either, depending on firmness

Combination Sleepers

If you change position throughout the night, you'll benefit from a mattress that responds quickly to movement.

Pocket sprung mattresses adjust independently as you move, providing consistent support whether you're sleeping on your side, back or stomach.

Best choice: Pocket Sprung

Lightweight Sleepers

People with a lighter body weight generally don't compress the mattress as deeply.

Both open coil and pocket sprung mattresses can be comfortable, although lighter sleepers often prefer softer comfort options that provide gentle cushioning and pressure relief.

Best choice: Either mattress type with an appropriate comfort level

Average-Weight Sleepers

Most people in the average weight range can comfortably sleep on either spring system.

If your budget allows, a pocket sprung mattress usually delivers better pressure relief, comfort and long-term durability for everyday use.

Best choice: Pocket Sprung

Heavier Individuals

People with a higher body weight place greater demands on a mattress and generally benefit from stronger support systems and more durable construction.

While a quality open coil mattress can provide adequate support, a well-made pocket sprung mattress—particularly one with higher spring counts and reinforced edge support—is often the better long-term choice. It distributes weight more effectively, helps maintain spinal alignment and is less likely to develop body impressions over time.

If you're a heavier sleeper, choosing the correct firmness is just as important as choosing the spring system. A firmer mattress with robust construction will usually provide the best combination of comfort and support.

Quick Recommendation by Sleeper Type

Sleeper Type	Recommended Mattress
Side sleepers	Pocket Sprung
Back sleepers	Pocket Sprung
Stomach sleepers	Either (with suitable firmness)
Combination sleepers	Pocket Sprung
Couples	Pocket Sprung
Guest bedrooms	Open Coil

Our Recommendation

Although both mattress types have their place, a pocket sprung mattress is the better option for most people. Its ability to provide targeted support, minimise motion transfer and adapt to different sleeping positions makes it a versatile choice for everyday comfort.

That said, an open coil mattress remains an excellent option if you're looking for reliable support at a more affordable price or need a mattress for occasional use, such as a guest room or children's bedroom.

If you're still unsure which mattress is right for you, it's also worth considering a hybrid mattress. By combining individually pocketed springs with advanced comfort layers, hybrid mattresses offer many of the benefits of pocket sprung construction alongside enhanced pressure relief and responsive comfort.

Frequently Asked Questions (FAQs)

Are pocket sprung mattresses better than open coil mattresses?

In most cases, yes. Pocket sprung mattresses generally provide better comfort, pressure relief and motion isolation because each spring works independently. This allows the mattress to adapt more closely to your body shape and reduce disturbance from a partner.

However, open coil mattresses still have value, especially if you're on a budget or need a mattress for occasional use such as a guest bedroom.

Is an open coil mattress good for everyday use?

An open coil mattress can be used every day, but it depends on the quality and your personal needs. Higher-quality open coil mattresses can provide reliable support, but they usually don't offer the same level of pressure relief or long-term durability as pocket sprung designs.

For long-term daily use, especially for couples or people with back or joint sensitivity, a pocket sprung mattress is usually a better option.

Do pocket sprung mattresses last longer than open coil mattresses?

Yes, on average pocket sprung mattresses tend to last longer. Because each spring moves independently, weight is distributed more evenly across the mattress, reducing wear in specific areas.

Open coil mattresses can wear faster because the springs are interconnected, meaning pressure on one area affects the entire structure.

Which is better for back pain: open coil or pocket sprung?

For most people, pocket sprung mattresses are better for back pain. They provide more targeted support to the shoulders, hips and lower back, helping maintain spinal alignment.

However, firmness also plays a major role. A poor-quality or too-soft pocket sprung mattress can still cause discomfort, so choosing the right firmness level is essential.

If back pain is a concern, you may also want to explore our dedicated guide to mattresses for back support and spinal alignment.

Are pocket sprung mattresses good for couples?

Yes. Pocket sprung mattresses are one of the best options for couples because they reduce motion transfer. This means you are less likely to feel your partner moving during the night.

They also provide more personalised support across the mattress surface, which helps when partners have different body weights or sleeping positions.

Do open coil mattresses sag faster?

They can, especially lower-quality models. Because the springs are connected, pressure is distributed across the entire structure, which can lead to sagging or body impressions over time.

Higher-quality open coil mattresses with strong fillings and good construction can last longer, but they still generally don't match pocket sprung durability.

Are pocket sprung mattresses worth the money?

For most people, yes. While they are more expensive than open coil mattresses, they offer better comfort, improved support and longer lifespan.

This makes them a strong long-term investment, especially if you use your mattress every night.

Which mattress is firmer: open coil or pocket sprung?

Neither type is inherently firmer. Firmness depends on the design, spring tension and comfort layers used in the mattress.

However, open coil mattresses often feel more uniformly firm, while pocket sprung mattresses can range from soft to very firm depending on construction.

Are pocket sprung mattresses hot to sleep on?

No, pocket sprung mattresses are generally breathable. The space between the springs allows air to circulate, helping regulate temperature.

Cooling performance depends more on the comfort layers (such as foam, latex or natural fillings) than the spring system itself.

Which mattress is better for heavy people?

Heavier sleepers usually benefit more from pocket sprung mattresses. They distribute weight more effectively and provide stronger long-term support.

A higher spring count, reinforced support and firmer tension level are especially important for maintaining comfort and preventing sagging over time.

What is the lifespan of an open coil mattress?

On average, an open coil mattress lasts around 2–7 years, depending on build quality and usage. Heavier use or lower-quality materials can reduce this lifespan.

What is the lifespan of a pocket sprung mattress?

A good-quality pocket sprung mattress typically lasts 7–10+ years. Premium models with high spring counts and durable comfort layers can last even longer with proper care.

Which mattress is better for guest rooms?

Open coil mattresses are often the best choice for guest rooms because they provide reliable comfort at a lower price point and are used less frequently.

Can I feel the springs in a pocket sprung mattress?

No, you should not feel the individual springs in a properly constructed pocket sprung mattress. The springs are enclosed in fabric pockets and covered with comfort layers that create a smooth sleeping surface.

If you can feel springs, it may indicate a low-quality or worn-out mattress.

Final takeaway

Both mattress types serve different purposes. Open coil mattresses are ideal for budget-friendly and occasional use, while pocket sprung mattresses offer superior comfort, support and durability for everyday sleeping.

If you're still unsure, a hybrid mattress combining pocket springs with advanced comfort layers may give you the best balance of support and pressure relief. The best mattress is the one that supports your body comfortably and promotes restful, uninterrupted sleep.
