Best Pocket Sprung Mattress UK 2026: What Spring Counts Really Mean

A pocket sprung mattress is still the best default for most British bedrooms: it sleeps cooler than memory foam, lets you move freely, and isolates a partner far better than the old open-coil beds it replaced. The best pocket sprung mattress in the UK for most people is the Simba Hybrid Pro, which puts up to 1,000 pocket springs and two layers of micro springs under a wool top. If you want a traditional British sprung bed for under £500, buy the Silentnight Comfort Breathe 1200 at £499 for a double. If you have a bad back and like it firm, the Dreams Dream Team Romsey is the cheapest bed Expert Reviews has called “the holy grail” for back-pain sufferers.

The single most useful thing this guide can tell you is that spring count is a weak buying signal. Which? tested mattresses with spring densities from 440 to 1,085 and found wide variation in support, concluding that quality matters more than quantity. Its pocket sprung guide is blunter still: “more springs doesn’t mean better support.” Once a mattress clears Which?’s floor of roughly 250 springs per square metre — about 640 in a UK double — you are paying for fillings, zoning, depth and build quality, not for the number on the label.

One line per sleeper. Couples and back sleepers: Simba Hybrid Pro. Tight budget, hot sleeper: Silentnight Comfort Breathe 1200. Firm, back pain, under £500: Dreams Romsey. Side sleepers: Emma Original, with five support zones and a 200-night refundable trial. Want the plush, layered-spring feel of a hotel bed: Sleepeezee Regency Kennington 4200. Natural fibres, money no object: Hypnos Inspired By Nature 05, the only two-sided mattress in our list. For the broader field, including all-foam options, see our best mattress UK rankings.

We picked these from what UK testers and spec sheets actually say, and we only included mattresses whose construction, price and care instructions we could verify on a page we opened in October 2026. That rules out a lot of high-street names that publish little beyond a marketing description. Where a price comes from a dated review rather than a live retailer page, we say so; mattress prices in Britain move almost weekly.

1. Simba Hybrid Pro — best overall. Strictly a hybrid, but it is a pocket sprung mattress at heart. Expert Reviews lists eight layers in 28cm: natural wool on top, a double layer of micro springs, open-cell foam, a “SupportCore” of up to 1,000 pocket springs for edge support, and a zoned foam base. Expert Reviews calls it “the most comfortable bed-in-a-box we’ve ever tested”, and TechRadar singles out average and heavier back and stomach sleepers. It lists at £1,299 for a double, has a 200-night trial and a 10-year warranty, and Simba scores 4.3 from more than 62,000 Trustpilot reviews. It is too firm for some light side sleepers. Full detail in our Simba review.

2. Silentnight Comfort Breathe 1200 — best budget, UK-made. A 25cm traditional pocket sprung mattress with 1,200 Mirapocket springs under breathable fibres, made in Silentnight’s Lancashire factory. £379 single, £499 double direct. Which? rates it “Cold” for warmth, which is exactly what you want from a sprung bed. The catch is the trial: 60 nights, exchange only, usable from night 28. Our Silentnight review compares it with the 1000 and 1400 Ortho.

3. Dreams Dream Team Romsey Pocket Sprung — best firm mattress under £500. A 22cm bed with individually wrapped pocket springs (561 in a single, 1,225 in a super king), a memory foam layer and a polyester “I-Fibre” comfort layer. When Expert Reviews tested it in March 2025 it cost £429 single, £479 double and £579 king, with a 100-night exchange trial. The reviewer measured just 13mm of sinkage near the edge under a 10kg weight, rating its edge support excellent, and called it “the holy grail” for people with lower-back pain. It is “too firm for lightweight sleepers, particularly those that sleep on their side”. Note the low spring count: it is the best evidence on this page that springs alone don’t decide support.

4. Emma Original — best for side sleepers. 25cm, five ergonomic support zones, a thicker memory foam layer and a medium feel. Emma doesn’t publish a spring count. It lists at £529 for a double, comes with a 200-night trial and full refund if you return it, and a 10-year warranty covering the spring core. Expert Reviews calls the 2026 model a great all-rounder but notes weak edges for sitting on. Emma’s Trustpilot score (3.3) is the weakest here, mostly over delivery and service. See our Emma review.

5. Sleepeezee Regency Kennington 4200 — best layered spring system. The spring count in a double is 3,576, up to 5,026 in a super king, spread across two layers of micro pocket springs above full-size pocket springs, with British wool and a pillow top. Expert Reviews (May 2026) loved it for light and average-weight back and side sleepers, praising its lumbar support, and found it firmer than the “medium firm” label. It costs £1,999 for a double through Dreams, weighs 50kg and is exchange-only within 100 nights, with a £95 collection charge.

6. Hypnos Inspired By Nature 05 — best natural, two-sided mattress. 31cm of 10-turn pocket springs wrapped in British wool, natural latex and a fruit-fibre layer, with fillings on both faces so you can flip it. Expert Reviews called it “a beautifully made and thoughtfully put together mattress” and rated the firm version one of the best for back pain. It is also £3,600 for a double, with only a 40-night exchange guarantee. If that is too much, John Lewis sells Hypnos’s Luxury Ortho Support No. 1 king, with 1,015 springs and 3kg of wool, at £1,699. Our Hypnos review maps the whole range.

A pocket sprung mattress has hundreds or thousands of steel springs, each sewn into its own fabric pocket. Because the pockets aren’t wired together, each spring compresses only as much as the weight directly on top of it. Your shoulder can sink further than your waist, and when your partner rolls over, the springs under them move while the springs under you mostly don’t. Which? puts it simply: each spring “reacts to pressure from your body independently.”

Above the springs sit the comfort layers, and this is where pocket sprung mattresses split into two camps. Traditional pocket sprung beds — the kind Silentnight, Hypnos, Sleepeezee and the high-street chains have made for decades — use fibres such as wool, cotton and polyester. Hybrids put foam, latex or micro springs on top instead, and are usually delivered rolled in a box. Which? notes that some mattresses sold as hybrids end up classed as pocket sprung after testing, because they are mostly spring core with a token foam layer. The label matters less than what is in the layers.

Pocket springs are by far the most common construction Which? tests: its results currently include 149 pocket sprung mattresses against 68 hybrids, 24 foam, 16 memory foam, 14 open coil and six latex. Which? also groups mattresses by warmth, and very few in its whole database are rated warm — four “Warm” and three “Very warm” against 131 “Cold” and 51 “Very cold”. If you have read that springs sleep cooler than foam, this is the British evidence behind it. For a US-focused deep dive into coil types and gauge, see the coil section of our best hybrid mattress guide; we won’t repeat it here.

An open coil mattress uses rows of springs joined together. Silentnight describes its open coil as an “interconnected spring system” linked by a single piece of wire, so the whole unit responds together. That makes it cheap to build — Which? says a basic open coil mattress “can start at less than £100” — but it has two weaknesses Which? spells out: the coils “tend to wear out more quickly than pocket springs”, and partners are more likely to disturb each other because movement travels along the wire.

Miracoil and Mirapocket are both Silentnight trademarks, which is why they confuse so many shoppers. Miracoil is Silentnight’s open coil system, made from one continuous wire and zoned so it “provides zoned support where your body needs it most.” Silentnight says it lets you sleep right to the edge, and that a double Miracoil has the usable sleep area of a king-size traditional open coil. Silentnight also admits open coils can get noisy as springs rub together with age. Mirapocket is Silentnight’s pocket sprung system, which it calls “an exclusive variation of the traditional pocket sprung mattress”: each spring sits in its own pocket. The Comfort Breathe 1000, 1200 and 1400 are all Mirapocket.

Which should you buy? Pocket sprung, unless the bed is for occasional use. A Miracoil or basic open coil is fine for a guest room or a child who will outgrow it, and the UltraGel Miracoil Pillowtop impressed Expert Reviews for temperature regulation. But for a main adult bed, the independence of pocket springs is worth the modest premium, and you don’t have to spend much to get it: Silentnight’s Comfort Breathe 1000 Pocket is £399 for a double. Expert Reviews did notice some motion transfer on the Miracoil UltraGel, which is exactly the weakness you would expect from connected springs.

The number in a UK mattress name — 1000, 1200, 1400, 2000, 4200 — is the headline spring count. It is the most heavily marketed spec in British bedding and the one testers trust least. There are four problems with it.

• The size is often missing. Silentnight doesn’t say which size its Comfort Breathe counts refer to. Dreams’ Romsey has 561 springs in a single and 1,225 in a super king — so a “1000” bed could have far fewer springs in the size you are buying.
• Mini springs inflate the total. The Kennington 4200 reaches 3,576 in a double because two layers of small micro springs sit above the main pocket unit. Silentnight’s 3000 model is 2,000 Mirapocket springs plus 1,000 smaller mini springs. Those small springs fine-tune comfort; they don’t do the same job as the support springs.
• Wire and turns matter as much as count. Hypnos makes a point of “10-turn” springs in its Inspired By Nature range, and edge-reinforced springs at the sides. A spring’s height, wire thickness and number of turns change how it pushes back.
• The lab says more isn’t automatically better. Which? tested densities from 440 to 1,085 and found wide variation in support; it says “a high spring count doesn’t automatically mean a better mattress”.

The chart makes the point visually. Price and spring count barely move together. The Dreams Romsey has fewer springs per size than most beds on the chart yet earned an excellent edge score and a back-pain recommendation at £479. Hypnos’s Ortho Support No. 1 costs £1,699 in king with 1,015 springs, little more than a £399 Silentnight on paper; what you are paying for is wool and a different spring. The Kennington tops the count by miles because of its micro-spring layers, and its price reflects the pillow top and wool as much as the springs.

So what should you do with the number? Use it two ways only. First, as a floor: Which?’s lab suggests more than 250 springs per square metre, which works out at around 640 in a UK double; nearly everything sold as pocket sprung clears that. Second, as a within-brand ladder: inside one maker’s range, a higher count usually comes with a deeper, firmer or better-filled mattress. Silentnight’s step from 1000 to 1200 adds a centimetre and £100 on a double; the step to 1400 Ortho adds 3cm, a firm rating and £150. That is a real change. Comparing a “1500” from one brand with a “2000” from another is not.

Our rule for 1000 vs 1500 vs 2000: 1,000 is plenty for a single or a guest double. For an adult couple’s main bed, around 1,200–1,500 in a double from a reputable maker is the sweet spot. Above 2,000, you are almost always buying mini-spring layers, which can make a mattress feel more contouring and hotel-like, but you should judge them on the fillings and the trial rather than the count.

“Nested” and “layered” springs are the two ways makers push counts up. Nested is a retail term for springs packed more densely into the same area; we couldn’t find a UK tester who measured what it changes, so treat it as a description, not a benefit. Layered or mini-pocket systems stack a second, smaller spring unit above the main one. The Sleepeezee Kennington 4200 is the clearest example we could verify: micro pocket springs, a high-density polyester support layer, a second set of micro springs, then full-size pocket springs and a polyester base. The Simba Hybrid Pro does something similar with a double layer of micro springs above its main core.

What does the extra layer buy? In the testers’ words, mainly finer contouring and lumbar support. Expert Reviews praised the Kennington’s “excellent lumbar support” and recommended it for light and average-weight back and side sleepers. The downside is weight and price. The Kennington double weighs 50kg — Which? notes the heaviest mattresses it tests top 50kg too, and its Silentnight Geltex 3000 listing hits 51kg — which matters if you need to rotate it weekly, as Sleepeezee recommends for the first three months. A layered bed is a luxury, not a support upgrade most people need.

This is the comparison most UK shoppers are really making, and the honest answer is that it depends on two things: how hot you sleep and how much your partner moves. Which?’s own pros and cons line up neatly. Memory foam “moulds to your body shape”, but it “can restrict movement” and “can feel warm to lie on.” Expert Reviews says the same: memory foam “absorbs heat, so can be uncomfortable for those prone to overheating at night.” Pocket springs breathe and push back, so you can roll over without climbing out of a dip.

Our verdict: choose pocket sprung if you run warm, change position a lot or dislike the slow sink of foam. Choose memory foam if your partner is restless and you sleep still, or if you need a light mattress you can carry up a narrow staircase. If you want some of both, buy a hybrid such as the Simba or Emma, which put foam or micro springs over a pocket core. Our memory foam vs hybrid guide covers the physics in more depth.

On firmness, both types follow the same evidence. The Kovacs randomised trial found medium-firm mattresses improved chronic low-back pain more than firm ones, and Radwan and colleagues’ systematic review favoured medium-firm surfaces for comfort and spinal alignment. That is why most of our picks are medium-firm, and why we only point you to very firm beds like the Romsey if you already know you like them. Our mattress firmness guide explains how to read UK firmness labels, which are less consistent than they look.

The layers above the springs decide how a pocket sprung mattress feels and how it ages. Traditional British makers use natural fibres: the Hypnos Inspired By Nature 05 uses two layers of British wool, a fruit-fibre layer woven with cotton, and natural latex; the Kennington adds British wool to its pillow top; Hypnos’s John Lewis Ortho Support No. 3 king carries 8.1kg of wool against 3kg in the No. 1. Boxed hybrids use foam instead, sometimes with a thin wool layer, as Simba does.

Natural fillings breathe. Wool and cotton wick moisture and let air move, which is why natural-filled beds tend to land in Which?’s cold bands. Expert Reviews recorded the Hypnos surface falling from 30°C to 23.1°C in ten minutes in its body-heat test. Which? notes that some hybrids, by contrast, “aren’t as breathable as other mattresses.”

Natural fillings also settle. Which? warns that some pocket sprung mattresses lose height as they age because “the layers compress”, and its buying guide lists significant sagging as a con of the type. Fibres compress where you lie, which is the real reason traditional makers tell you to rotate or turn regularly. Foam layers sag too, but more slowly if the foam is dense. Neither is wrong; just know that a natural-filled mattress asks for more upkeep in return for breathing better.

Pocket springs were invented partly to solve the couples problem. Silentnight claims that with Mirapocket “your partner won’t feel a thing” when you move. That is marketing, but the principle is sound, and Which? confirms the comparison: partners are more likely to disturb each other on open coil than on pocket springs. All-foam beds still absorb motion better, and a springy pocket bed with a soft top lets some movement through.

For couples we would buy the Simba Hybrid Pro. Its micro-spring layers and foam damp movement better than a traditional fibre-topped bed, its SupportCore springs are there specifically for edge support, and a double weighs about 40kg with side handles — manageable to rotate. If you are on a budget, the Silentnight Comfort Breathe 1200 is a reasonable couple’s bed, but if one of you is a light sleeper the 60-night exchange-only trial gives you little room to get it wrong. Couples who disagree on firmness should weigh up size too: a super king gives each of you 90cm, the same width as a single. Our UK mattress sizes guide has the dimensions, and our best mattress for couples page covers motion isolation in depth.

The old advice to turn your mattress every few months comes from the era of two-sided beds, and it still applies to them. Most modern pocket sprung mattresses are single-sided, which changes the job: you rotate them head to toe instead of flipping them over. Which? puts it plainly — one-sided mattresses “won’t need to be turned over regularly”, but you should still rotate them. Getting this wrong matters. Flip a one-sided hybrid and you are sleeping on the base layer; never rotate a traditional bed and you will wear a permanent hollow where you lie.

The rules our picks give are not consistent, so follow the label on yours. Silentnight’s Mirapocket guidance is to turn every three to six months. Sleepeezee asks owners of the no-turn Kennington to rotate it “every week for the first three months and every month thereafter”, while the fillings bed in. Emma says of the Original, “The mattress is single-sided, do not flip it.” Simba’s Hybrid Pro and the Dreams Romsey can’t be flipped either; Expert Reviews advises rotating the Romsey regularly to stop dips forming. Only the Hypnos Inspired By Nature 05 is genuinely two-sided, and Expert Reviews warns that flipping a 31cm natural mattress is hard work.

How long should a pocket sprung mattress last? Silentnight says seven to ten years, depending on quality, use and the base underneath. Which?’s durability test rolls a heavy barrel over each mattress around 30,000 times to look for sagging. A guarantee won’t cover gradual softening, so regular rotation is the cheapest insurance you have. Our mattress lifespan guide covers the signs that it is time to replace one, and a mattress topper can buy a tired bed a year or two.

A pocket sprung mattress is the right call for most people, but not all. Skip it if:

• You share with a very restless partner and sleep lightly. All-foam isolates motion better. Look at memory foam options on our UK rankings.
• You need to carry the mattress yourself. Traditional pocket sprung beds are heavy — 50kg or more for some doubles — and can’t be rolled unless sold as rollable.
• You are allergic to wool or latex. Many premium British models use both.
• You want a long, refundable trial on a traditional bed. The high-street and heritage makers mostly offer exchange-only trials of 40 to 100 nights. Boxed hybrids such as Simba and Emma give 200 nights with refunds.
• It is for occasional use. A cheap open coil or Miracoil is fine for a box room.

Everyone else should start with the Simba Hybrid Pro if budget allows and the Silentnight Comfort Breathe 1200 if it doesn’t, and judge every other bed on fillings, trial and care rules rather than the spring count in its name.
