Best Pocket Sprung Mattress UK: How to Choose (2026)
If you’re trying to find the best pocket sprung mattress UK retailers sell, you’ve probably noticed that every site quotes different spring counts, firmness scales and prices, which makes comparing like-for-like almost impossible. This guide explains what pocket sprung actually means, how spring counts really work, how to pick the right firmness for your body and sleep position, and what a sensible budget looks like at every UK size.
What does pocket sprung actually mean?
A pocket sprung mattress is built from hundreds or thousands of individual springs, each stitched into its own fabric pocket. Because every spring sits independently, it only compresses where weight is applied, rather than the whole surface moving together.
This matters for two practical reasons. First, if you share a bed, movement on one side doesn’t send a ripple across to the other side, which helps if your partner gets up in the night. Second, pocket springs tend to follow the contours of your body more closely than a solid spring unit, giving more even support along your spine.
Pocket sprung mattress vs open coil: what’s the difference?
Open coil is the older, more traditional spring system. The coils are joined together by a single length of wire, arranged in rows, with a stiffer wire border for strength. Because the springs are linked, the whole mattress tends to move and flex as one unit.
Open coil mattresses are usually the cheapest option on the market and can be perfectly adequate for guest rooms or occasional use. But if you’re a couple, a lighter sleeper, or you want more precise support around the hips and shoulders, a pocket sprung mattress vs open coil comparison almost always favours pocket springs for everyday use.
How many springs should a good pocket sprung mattress have?
Spring count is one of the most quoted — and most misunderstood — numbers in mattress shopping. As a rough guide:
- Around 1,000 springs is generally considered an entry-level count for a king size mattress.
- 1,500–2,000 springs is a higher quality, more supportive range.
- Over 2,000 springs is a premium count, usually achieved with dual-layer or mini-spring construction rather than a single layer.
Here’s the part most guides skip: marketed spring counts are almost always based on a king size mattress. A single will naturally have fewer springs because it’s a smaller surface, and a super king will have more. So a single quoted at “600 springs” isn’t necessarily lower quality than a king quoted at “1,000” — it may have the same spring density per square metre, which is really the number that tells you about quality and support.
As a size-by-size rule of thumb, singles typically carry 600–800 springs, doubles 800–1,200, kings around 1,000–2,000, and super kings scale up proportionately again. When comparing two mattresses, it’s more useful to compare springs per square metre, or at least compare spring counts within the same size, than to take the headline number at face value.
Pocket sprung mattress vs memory foam: which is better?
This is a genuine trade-off rather than one option being universally “better.”
- Temperature regulation: pocket sprung mattresses generally sleep cooler. The gaps between individual springs allow air to circulate, and many use natural fillings like cotton or wool in the comfort layers on top, which help manage warmth and moisture. Memory foam is more heat-sensitive and can feel warmer, particularly in summer.
- Pressure relief: memory foam tends to win here, as it moulds closely to the body and can ease pressure points for some sleepers.
- Edge support and motion isolation: pocket springs generally offer firmer edges to sit and sleep near, and the independent coil design reduces the “roll-together” effect in shared beds.
If you tend to sleep hot, or you share a bed and want to minimise disturbance, pocket sprung is usually the safer bet. If pressure relief is your main concern, a hybrid design — pocket springs topped with a foam comfort layer — can give you a bit of both. Our Premium Hybrid Mattress pairs 8cm individually wrapped pocket springs with a breathable Octaspring® comfort layer, giving you spring-like bounce with foam-style contouring. For a deeper, softer feel, the Premium Hybrid Deluxe Mattress adds 50% more foam over the same pocket spring base.
Is a pocket sprung mattress good for back pain?
Even support along the length of the spine is generally considered helpful for comfort, and pocket springs are designed to respond to the body’s shape rather than leaving gaps under the lower back or neck. A medium-firm feel is the most commonly recommended starting point for general back support.
That said, we can’t give medical advice, and mattress choice alone won’t resolve ongoing back pain. If you have persistent or worsening pain, it’s worth speaking to a GP or physiotherapist, who can advise on sleep position and any underlying causes before you commit to a new mattress.
How much should you budget for a pocket sprung mattress?
Prices vary a lot by size, spring count and comfort layers, but here’s a general shape of the market:
| Price band | What you typically get |
|---|---|
| Budget | Entry-level spring counts (around 800–1,000 for a king), simpler comfort layers — fine for guest rooms or occasional use. |
| Mid-range | 1,000–2,000 springs, added padding layers such as foam or natural fibres, better edge support and longer expected lifespan. |
| Premium | High spring counts or dual-layer spring systems, deeper comfort layers, often hybrid constructions with foam or natural fillings. |
If you’re searching for a pocket sprung mattress under 500, you’re generally in mid-range territory — enough springs and padding for genuinely comfortable everyday sleep without stretching to premium hybrid pricing. Our Comfort 800 Mattress is a solid example, with a medium firmness rating and a body-conforming design that helps prevent roll-together, backed by a 10 year manufacturer’s warranty. The Space 3000 Mattress steps things up with individual pocket springs and complete head-to-toe support, also with a 10 year warranty.
All mattresses and beds ordered from Furnmart come with free UK mainland delivery, which is worth factoring in when you compare total cost across retailers.
Choosing the right firmness or tension
Firmness is personal, and there’s no single UK-wide firmness scale, so ratings aren’t always directly comparable between brands. As a starting point:
- Side sleepers generally suit soft to medium-firm, which allows the shoulder and hip to sink in slightly.
- Back sleepers usually do best on medium-firm, supporting the natural curve of the spine.
- Stomach sleepers tend to need medium-firm to firm, to avoid the hips dipping too low.
- Combination sleepers who move around in the night often find medium-firm the most adaptable choice.
Body weight also plays a part: heavier individuals often find a firmer tension more supportive, while lighter sleepers may prefer something softer, as they won’t compress the springs as deeply. For couples with different body types, a split-tension or zoned support mattress — firmer on one side, softer on the other — can solve a lot of disagreements.
Where possible, test a mattress in person before buying. If you’re buying online, check the retailer’s trial or returns policy so you have the option to adjust if the tension doesn’t suit once you’ve slept on it for a week or two.
Pocket sprung mattress sizes and how size affects price
UK mattresses come in a standard set of sizes, and it helps to know the exact dimensions before you buy:
- Small single – 2’6″
- Single – 3’0″
- Small double – 4’0″
- Double – 4’6″
- King – 5’0″
- Super king – 6’0″
Because spring count and materials scale with surface area, larger sizes cost more even when the “quality tier” is identical — a super king needs considerably more springs and filling than a single to maintain the same support and density. This is why comparing a pocket sprung mattress single against a pocket sprung mattress king size purely on headline spring count can be misleading; always check whether the figure quoted is per size or a standard king benchmark.
If you’re furnishing a child’s room, a Deluxe Pocket Sprung Mattress Single Continental is a straightforward single-size option that combines a supportive sprung core with quality comfort layers. For a cooler, more contouring feel in larger sizes, the Sareer Pocketo 2000 Cool Blue Pocket Memory Mattress uses a 2000 pocket spring unit with a cooling memory foam layer and is available from small single right up to super king.

Depth, bed frames and a few practical extras
Before you buy, check the mattress depth against your bed frame. A deep, premium pocket sprung or hybrid mattress can look disproportionate — or simply not fit — inside a shallow divan base or a bed frame with low side rails. If you’re using an adjustable base, confirm the mattress is compatible; not all pocket sprung constructions flex well at the hinge points.
To help your mattress last, rotate it head-to-foot every few weeks for the first few months and then periodically after that, and avoid folding or standing it on its side, which can damage the internal springs. Most good quality pocket sprung mattresses are designed to perform well for around 7–10 years, though this depends on usage, care and the quality of the original build.
If allergies are a concern, natural fillings such as wool and cotton are generally breathable and can help with moisture control, though always check the specific mattress’s care label for cleaning guidance.
Browsing bed frames at the same time? Our beds range and ottoman beds category both have options with varying base heights worth checking against your chosen mattress depth. If you’re still deciding between a storage bed and a standard frame, our divan bed vs ottoman bed guide covers the practical differences.
Frequently asked questions
What’s the difference between pocket sprung and open coil mattresses?
Pocket sprung mattresses use individually wrapped springs that move independently, giving more precise support and less motion transfer. Open coil mattresses link springs together with a single wire, so the whole surface moves as one unit — generally cheaper but less contouring.
Is a higher spring count always better?
Not necessarily. Spring count needs to be compared within the same mattress size, or ideally as springs per square metre, since marketed figures are usually based on a king size mattress and will naturally look lower for a single and higher for a super king.
Can a pocket sprung mattress help with back pain?
A medium-firm pocket sprung mattress can provide even support along the spine, which many people find comfortable. For ongoing or worsening back pain, it’s best to speak to a GP or physiotherapist rather than relying on mattress choice alone.
Do pocket sprung mattresses sleep cooler than memory foam?
Generally yes. The gaps between individual springs allow better airflow, and many pocket sprung mattresses use breathable natural fillings in the comfort layer, whereas memory foam can retain more body heat.
What’s a reasonable budget for a pocket sprung mattress under 500?
This typically buys a mid-range mattress with a solid spring count and added comfort layers, suitable for everyday use rather than occasional guest rooms. Exact pricing depends on size, so always compare the same size across retailers.
