A pocket sprung mattress is still one of the most popular choices in the UK, and for good reason: individually wrapped springs contour to your body, isolate movement from a partner, and breathe better than all-foam alternatives. But "pocket sprung" covers a huge range of quality, from basic 1,000-spring budget models to 3,000-spring luxury builds. This guide explains what actually matters when you're choosing one, so you can buy with confidence rather than guessing from a spec sheet.

What Is a Pocket Sprung Mattress?

Inside a pocket sprung mattress, each spring sits in its own fabric pocket rather than being wired together in a single interconnected unit, as with older open coil designs. Because every spring compresses independently, the mattress responds to the specific shape and weight distribution of your body rather than sagging as one uniform sheet.

How This Differs from Memory Foam and Open Coil

Open coil mattresses use one continuous wire framework, so pressure in one area causes movement across the whole surface — not ideal if you share a bed. Memory foam mattresses contour closely and absorb motion well, but some sleepers find them too warm or slow to respond. Pocket springs sit between the two: supportive and responsive like a traditional mattress, but with much better motion isolation and, in most builds, better airflow than solid foam. Many mattresses today are actually hybrids, pairing a pocket spring base with a foam or latex comfort layer — you'll see several options like this further down.

The Benefits of a Pocket Sprung Mattress

• Targeted support: springs compress independently, so shoulders and hips sink slightly while the lower back stays supported.
• Motion isolation: a partner moving or getting up shouldn't disturb your side of the bed.
• Airflow: the pocketed spring structure allows air to move through the mattress core, which helps regulate temperature overnight.
• Durability: a well-built pocket sprung mattress with a reasonable spring count typically holds its shape for 7–10 years with proper care.
• Edge support: quality builds reinforce the perimeter, so the mattress doesn't collapse when you sit on the side to get dressed.

How Many Springs Do You Actually Need?

Spring count is the number most retailers lead with, but it only tells part of the story. As a practical UK benchmark, look for somewhere in the range of 1,000 to 2,000 springs in a double mattress, or roughly 350–500 springs per square metre. Below that, support tends to feel inconsistent. Above 2,000, you're mostly paying for a marketing number — the difference in comfort becomes marginal once you're past around 2,000–3,000 springs, and factors like zoning, fillings and cover quality start to matter more than raw count.

What matters more than the headline figure is zoning — whether the mattress uses firmer springs under the hips and shoulders and softer ones elsewhere to keep the spine aligned — and the quality of the comfort layers sitting above the springs.

Pocket Sprung vs Memory Foam vs Hybrid

If you sleep hot, move around a lot in the night, or share a bed, pocket sprung or a pocket-sprung hybrid is usually the safer choice. If you want maximum pressure relief and don't mind a warmer sleep surface, all-foam memory foam can work well, particularly for side sleepers with joint pain. Hybrid mattresses — a pocket spring base topped with memory foam, latex or a pillow-top layer — are worth considering if you want the best of both: the support and airflow of springs with the contouring comfort of foam.

Firmness: Matching the Mattress to How You Sleep

Side Sleepers

Look for a medium or medium-soft feel with enough give at the shoulder and hip to keep the spine level. A firm mattress can create pressure points at these joints.

Back Sleepers

Medium to medium-firm tends to work best, supporting the natural curve of the lower back without letting the hips sink too far.

Front Sleepers

A firmer mattress helps prevent the midsection from dipping, which can strain the lower back over a night's sleep.

If back pain is a specific concern rather than just sleep position, our guide to choosing the best bed and mattress for back pain goes into more detail on base and mattress combinations.

Sizes and Fit

Pocket sprung mattresses are made in all standard UK sizes, from 2ft6 small single through to 6ft super king. If you're not sure which dimensions suit your room or bed frame, our UK bed sizes guide covers every measurement in cm, inches and feet.

What to Check Before You Buy

• Zoning: does the listing mention zoned or targeted support, rather than a single uniform spring type?
• Edge support: reinforced border springs stop the mattress collapsing at the sides.
• Depth: deeper mattresses (25cm+) generally have more room for supportive comfort layers, though this isn't a hard rule.
• Cover: a breathable, removable or washable cover makes long-term care easier.
• Warranty: UK retailers typically offer 5–10 years on pocket sprung builds — check what's covered.

Caring for Your Pocket Sprung Mattress

Rotate the mattress head to foot every two to three months to encourage even wear — pocket sprung mattresses don't need flipping unless the manufacturer says otherwise, since most are one-sided. Use a breathable mattress protector to guard against spills and allergens without trapping heat, and air the room regularly to help the mattress manage moisture. Avoid sitting in the same spot repeatedly, which is the most common cause of premature sagging at the edge.

Frequently Asked Questions

How many springs should a good pocket sprung mattress have?

Somewhere between 1,000 and 2,000 springs in a double is a sensible UK benchmark. Beyond around 2,000–3,000, the comfort difference becomes marginal, and zoning and comfort layers matter more than the raw count.

Are pocket sprung mattresses good for a bad back?

Many people with back pain do well on a medium to medium-firm pocket sprung mattress, since the zoned support keeps the spine aligned. If back pain is ongoing, it's worth speaking to a healthcare professional about your specific needs alongside choosing the right mattress.

Do pocket sprung mattresses sleep hot or cool?

Generally cooler than all-foam memory foam, because air can move through the spring core. A breathable cover and natural fillings such as latex or wool improve this further.

How long does a pocket sprung mattress last?

A well-made pocket sprung mattress with a reasonable spring count typically lasts 7–10 years with regular rotation and a supportive base.

Can I use a pocket sprung mattress on a divan or ottoman base?

Yes — pocket sprung mattresses work on divan bases, ottoman storage beds, and slatted frames, though it's worth checking the manufacturer's guidance on base compatibility for slatted frames specifically.

Final Thoughts

A pocket sprung mattress remains one of the most reliable choices for UK sleepers who want a balance of support, motion isolation and airflow. Focus less on the spring count printed on the label and more on zoning, edge support, firmness suited to how you sleep, and a cover that will hold up over years of use.
