You are lying on a mattress in John Lewis, trying to decide whether the one priced at £1,400 is really three times better than the one at £450 next to it. They both feel comfortable. The sales assistant is hovering. And you have no idea whether spending more actually gets you more sleep or just a lighter wallet.
It is one of the most confusing purchases you will make for your home. Mattress pricing in the UK ranges from about £150 for a basic open coil to over £3,000 for handmade pocket sprung models, and the gap between what you pay and what you get is not always obvious. This guide breaks down how much a mattress actually costs in the UK in 2026, what drives the price differences, and where the real value sits — so you walk into that showroom knowing exactly what to spend.

UK Mattress Prices in 2026: A Realistic Overview
Mattress prices in the UK vary enormously, but here is a broad breakdown of what you will actually pay for a double (135 × 190 cm) in 2026:
- Under £200 — basic open coil or thin foam. Functional but short-lived. Guest room territory.
- £200–£400 — entry-level memory foam or simple pocket sprung. Decent for a first home or spare bedroom.
- £400–£700 — the mid-range where most people should shop. Good pocket sprung (800-2,000 springs), quality memory foam, or hybrid models from established brands.
- £700–£1,200 — premium pocket sprung (2,000+ springs), natural latex, pillow-top hybrids. Noticeably better materials and longevity.
- £1,200–£2,000+ — handmade, natural fillings (wool, cotton, horsehair), luxury brands. Diminishing returns above £1,500 for most sleepers.
- £2,000+ — bespoke and ultra-premium. Hypnos, Vispring, Harrison Spinks at the top end. Beautifully made but the performance gap narrows sharply above this point.
The NHS recommends prioritising sleep quality as a foundation for overall health, and your mattress is central to that — but you do not need to spend a fortune to sleep well.
What Makes One Mattress Cost More Than Another
Materials
The biggest price driver. Open coil springs are the cheapest to manufacture. Pocket springs cost more because each spring sits in its own fabric sleeve — more labour, more material, better support. Memory foam pricing depends on density: cheap foam (under 40 kg/m³) compresses permanently within a year; high-density foam (50-80 kg/m³) holds its shape for a decade.
Natural materials push prices up further. Latex from rubber trees costs more than synthetic foam. Wool, cotton, and silk comfort layers add £100-300 per layer versus polyester.
Spring Count
A double mattress with 600 open coils costs about £200 to manufacture. One with 2,000 individual pocket springs costs roughly £400-500 in materials alone. Above 2,000 springs, the benefit is incremental — a 3,000-spring mattress is not 50% better than a 2,000-spring one, despite often being 50% more expensive.
Brand and Retail Markup
Here is the uncomfortable truth: many mattress showroom prices include 60-70% retail markup. That £1,200 mattress may have cost £350-400 to make. This is why mattress-in-a-box brands like Emma, Simba, and Eve can sell seemingly similar specs for less — they cut out the showroom. It is also why mattress sales are so aggressive. Nobody pays full price for a sofa, and the same logic applies to mattresses.
Certifications
Legitimate certifications like OEKO-TEX Standard 100, CertiPUR, and the UK Fire Safety regulations (BS 7177) add cost. These are worth paying for — they guarantee the foams do not contain harmful chemicals and meet British fire safety standards. Our mattress certifications guide explains what each certification actually means.
The Budget Tier: £150–£400
What You Get
At this price, expect either an open coil mattress with a basic foam or polyester comfort layer, or an entry-level memory foam mattress. Spring counts will be low (300-600 for open coil, or 800 pocket springs at the top end). The cover fabrics are functional rather than luxurious.
Who Should Buy Here
- Spare bedrooms and guest rooms
- University students
- Children who will outgrow the mattress within a few years
- Anyone on a genuinely tight budget who needs a new mattress now
Specific Recommendations
- Silentnight Eco Comfort Miracoil (about £200 from Argos) — Silentnight’s entry-level with their continuous coil system. Not pocket sprung, but decent edge support and a 5-year guarantee.
- IKEA ÅBYGDA (about £175) — a basic pocket sprung from IKEA that outperforms its price. 560 pocket springs in a double. No frills, no fancy cover, but the spring unit is honest.
- Emma Essential (about £350) — the budget option in Emma’s range. Three foam layers, reasonable support. Comes with a 200-night trial which removes the risk.
The Honest Truth About Budget Mattresses
They work. For a year or two, a £250 pocket sprung mattress feels perfectly adequate. The problem is longevity — after three years the support layers start compressing, and by year five you are sleeping in a hammock shape. If you buy budget, plan to replace sooner.
The Mid-Range Sweet Spot: £400–£900
This is where the best value lives. You are past the corner-cutting of budget mattresses but not yet paying the premium brand tax. After sleeping on mattresses across every price range over the years — from a £150 IKEA to a £1,800 Hypnos — the difference between £500 and £1,500 is much smaller than the difference between £200 and £500.
What You Get
Pocket spring counts of 1,000-2,000. Quality memory foam or latex comfort layers. Better cover fabrics (often knitted, temperature-regulating). Edge support that does not collapse when you sit on the bed. Our best mattresses roundup covers the top performers across this range.
Specific Recommendations
- Emma Original (about £530 for a double) — consistently rated the best all-rounder in the UK mattress-in-a-box market. Three foam layers, medium-firm, and a 200-night trial. Regularly on sale for £400-450.
- Simba Hybrid (about £600) — combines pocket springs with foam for a responsive feel. The springs sit inside the foam rather than below it, which creates a different sleeping surface from traditional hybrids. We compared this against its main competitors in our Emma vs Simba vs Eve showdown.
- Brook + Wilde Lux (about £700) — choose your firmness level (soft, medium, or firm) before ordering. Good quality pocket springs with a responsive foam top. The 200-night trial and free returns make it low risk.
- Hypnos Orthos Support 6 (about £850 from John Lewis) — if you prefer a traditional pocket sprung mattress bought in a showroom, Hypnos at this price point delivers. 1,400 pocket springs, wool and cotton fillings, and the reassurance of a brand that has been making mattresses since 1904.
The Premium Tier: £900–£2,000+
What You Get
This is where craftsmanship and materials become noticeably different. Hand-tufted construction (not glued layers). Natural fillings: British wool, cotton, silk, cashmere, and sometimes horsehair. Pocket spring counts of 2,000-4,000+. These mattresses are heavier, thicker, and built to last 10-15 years without sagging.
Is It Worth the Money?
After spending time on mattresses at every price point — the performance gap between a £700 and a £1,400 mattress is real but narrow. The £1,400 mattress will likely last 12-15 years instead of 8-10, the materials feel more luxurious, and the edge support is rock solid. But you are not going to sleep twice as well.
Where premium makes sense: if you weigh over 100 kg (higher quality springs hold up better), if you have chronic back issues (natural latex and pocket springs offer better targeted support), or if you keep mattresses for the full 10+ years rather than replacing every 5-7.
Specific Recommendations
- Simba Hybrid Pro (about £950) — adds a layer of springs and bamboo fibre to the standard Hybrid. Noticeably cooler and more responsive.
- Hypnos Pillow Top Celestial (about £1,400 from John Lewis) — hand-tufted, natural fillings, 1,600 pocket springs. This is the point where Hypnos moves from very good to exceptional.
- Harrison Spinks 3000 (about £1,200) — uses up to 3,000 micro springs. Harrison Spinks is Yorkshire-based and manufactures everything in-house, including the springs. Properly excellent.
Mattress-in-a-Box vs Traditional Showroom Pricing
Why Boxed Mattresses Cost Less
The business model is different. Emma, Simba, Eve, and Brook + Wilde sell direct to consumer online, cutting out showroom rent, sales staff, and retail markup. A mattress that would cost £800 in John Lewis can be priced at £500-600 as a boxed mattress with similar or better specs.
The Trade-Off
You cannot try before you buy — though the 100-200 night trials largely solve this. Boxed mattresses tend to be foam or foam-hybrid rather than traditional pocket sprung with natural fillings. If you prefer a classic sprung feel with wool layers, you will probably end up in a showroom.
The Price Gap Is Shrinking
Traditional brands have noticed. Silentnight, Sleepeezee, and even Hypnos now sell some models online. John Lewis has expanded its online mattress range with detailed comparison tools. The days of needing to visit three showrooms on a Saturday afternoon are fading — though for mattresses over £1,000, I still recommend trying in person if you can.
Does Mattress Size Affect Value for Money?
Price Scaling by Size
UK mattress sizes and their typical price ratios relative to a double:
- Single (90 × 190 cm) — about 60-70% of the double price
- Double (135 × 190 cm) — base price
- King (150 × 200 cm) — about 110-130% of the double price
- Super King (180 × 200 cm) — about 130-160% of the double price
The Best Value Move
A king mattress typically costs only £50-150 more than a double for the same model. For two people sharing, that extra 15 cm of width makes a meaningful difference to sleep quality. If your bed frame accommodates it, upgrading from double to king is one of the best value-for-money decisions in bedding. Our guide to mattress costs under £500 includes king-size options that stay within budget.
When Sales Are Worth Waiting For
The UK Mattress Sale Calendar
Mattress companies run sales constantly, but some are better than others:
- January sales — genuine clearance of previous year’s stock. Discounts of 30-50% are real.
- Black Friday / Cyber Monday (November) — the biggest single sale event. Emma, Simba, and Eve typically offer 40-55% off. Showroom brands match with similar discounts.
- Bank Holiday weekends (May, August) — reliable 20-30% off from most retailers.
- Amazon Prime Day (July) — boxed mattresses often feature. Less reliable than Black Friday but worth checking.
- Mid-season (March, September) — quieter periods. Less likely to find big sales, but sometimes you can negotiate in showrooms when foot traffic is low.
Are the Discounts Real?
Mostly yes for boxed mattresses — their “RRP” is usually the genuine non-sale price. For showroom brands, treat the sale price as the real price. If a mattress is £1,200 and constantly “on sale” at £800, the £800 is what it actually costs. The trading standards rule: the higher price must have been charged for 28 consecutive days in the previous 6 months. Most mattress retailers comply, but the sales are so frequent that the full price is almost theoretical.
How Long Should Your Mattress Last (And Cost Per Night)
Expected Lifespan by Type
- Open coil — 3-5 years before noticeable sagging
- Basic foam — 4-6 years
- Quality pocket sprung — 7-10 years
- Premium pocket sprung (natural fillings) — 10-15 years
- Latex — 10-15 years (latex is remarkably durable)
Cost Per Night
This is the metric that makes expensive mattresses seem reasonable:
- A £250 mattress lasting 4 years = about 17p per night
- A £550 mattress lasting 8 years = about 19p per night
- A £1,200 mattress lasting 12 years = about 27p per night
- A £2,000 mattress lasting 15 years = about 37p per night
The difference between budget and mid-range is 2p per night. Even the jump to premium is only 10p more. When you frame it that way, spending £550 instead of £250 is an obvious decision — the per-night cost barely changes but the comfort and longevity improve substantially.

Where to Buy a Mattress in the UK
Online (Boxed Mattresses)
- Emma (emma-sleep.co.uk) — best all-rounder, aggressive sales
- Simba (simbasleep.com) — hybrid specialist
- Eve (evesleep.co.uk) — now part of Bensons, still sells online
- Brook + Wilde (brookandwilde.com) — firmness choice model
High Street / Showrooms
- John Lewis — excellent range, knowledgeable staff, 7-year guarantees on many models
- Dreams — UK’s largest mattress retailer. Good range but aggressive upselling. Know what you want before walking in.
- Bensons for Beds — mid-range to premium. In-store fitting service is useful.
Hybrid Approach
Buy in-store after trying, but check the online price first. John Lewis price-matches. Dreams occasionally does too. If the boxed mattress version of a similar spec is £200 cheaper, that is worth knowing before you commit.
How to Avoid Overspending
Know Your Floor and Ceiling
Before you start shopping, set two numbers: the minimum you are willing to spend (your floor) and the absolute maximum (your ceiling). For most couples buying a double, a floor of £400 and a ceiling of £800 covers the sweet spot where quality and value overlap.
Do Not Let Comfort in the Showroom Justify Overbuying
Lying on a £2,000 mattress for two minutes in a showroom feels incredible because it is new and you are comparing it to a saggy 8-year-old mattress at home. A £600 mattress will also feel incredible when it arrives. The showroom comparison is fundamentally unfair.
Ignore Feature Creep
“Cooling gel infusion,” “graphene layer,” “copper thread technology” — most of these are marketing terms that add £100-200 to the price with minimal real-world benefit. Focus on spring count, foam density, and the trial period.
Always Check the Guarantee
A 10-year guarantee from a brand that has existed for 5 years is meaningless. Hypnos, Silentnight, Harrison Spinks, Vispring — these are brands with decades of track record behind their guarantees. For newer brands, the trial period (100-200 nights) matters more than the warranty.
Frequently Asked Questions
How much does a good mattress cost in the UK? A good mattress in the UK costs between £400 and £900 for a double. This mid-range delivers quality pocket springs or hybrid construction, reliable comfort layers, and 7-10 year durability. Below £400 is functional but short-lived; above £900 offers luxury materials and longer lifespan but with diminishing returns on comfort.
Is it worth spending £1,000 or more on a mattress? It can be, particularly if you weigh over 100 kg, have back problems, or keep mattresses for 10+ years. Premium mattresses use natural fillings and higher spring counts that maintain support longer. But for most sleepers, the difference between a £600 and a £1,200 mattress is subtle — spend the extra only if durability and craftsmanship matter to you.
Are mattress-in-a-box brands as good as traditional mattresses? Yes, for their intended use. Emma, Simba, and Brook + Wilde produce mattresses that compete with or beat showroom equivalents at the same price. The main difference is that boxed mattresses are typically foam or foam-hybrid, while showroom brands offer traditional pocket sprung with natural fillings. Both can deliver excellent sleep.
When is the best time to buy a mattress in the UK? Black Friday and January sales offer the deepest discounts — typically 30-55% off. Bank Holiday weekends (May and August) are also reliable. Boxed mattresses run sales frequently, so check the current price before paying full RRP. For showroom brands, the sale price is the real price.
How often should you replace your mattress? Every 7-10 years for a quality pocket sprung or hybrid, 4-6 years for budget foam or open coil, and 10-15 years for premium natural-filling or latex models. If you wake with aches, see visible sagging, or the mattress dips noticeably where you sleep, it is time regardless of age.
