Can a cheap mattress actually be good?#

Yes, within limits. Price buys you better materials, deeper comfort layers and longer warranties, but the single biggest factor for your back, firmness, costs nothing extra. A systematic review of 39 studies found that medium-firm mattresses best support comfort, sleep quality and spinal alignment,1 and you can hit a medium-firm feel at almost any price point. The trick is knowing where it is safe to save and where it is not.

Best under £150: Westwood Memory Foam#

The Westwood from The Foam People is made to order in the UK from a simple two-layer foam recipe, and at £109 it scored 9.3 for value, the highest on the site. It's an 18cm build, so it suits lighter adults, children and guest beds best; heavier nightly sleepers should spend up to a deeper model.

Best budget cooling: Core CoolMax Memory Foam#

Budget foam usually means hot foam. The Core CoolMax counters it with a moisture-wicking CoolMax cover over its memory foam for £147, the cheapest credible answer for warm sleepers, alongside its sibling pick in our cooling guide.

Best light-sleeper pick: Core Bubble Memory#

The Core Bubble Memory pairs a cushioning "bubble" comfort layer with a supportive core for £148. All-foam builds like this absorb a partner's movement almost completely, useful if you wake easily.

Best budget firm: Comfort Ortho Firm#

Genuinely firm budget mattresses are usually just thin. The 20cm Comfort Ortho Firm uses a dense supportive core to earn its 8.6 support score, our budget answer for front sleepers and firm-preferring backs at £157. Read the evidence on firmness and back pain in our orthopaedic guide first.

Best budget for side sleepers: Saffron Comfort Deep#

The 23cm Saffron Comfort Deep has the deepest comfort layer of the sub-£200 picks, enough give at the shoulder for side sleeping without bottoming out at the hip. £174.

Best budget luxury feel: Superior Cashmere#

A cashmere-blend cover at £198: the Superior Cashmere is The Foam People's plushest build and the pick when you want a spare room to feel like a hotel, full detail in our review.

Best brand-name budget buy: Emma Original Lite#

The Emma Original Lite trims the Original's build to 20cm but keeps the 200-night trial and 10-year warranty, by far the longest cover at this price. Value score: 9.4. If trial length is what lets you sleep at night, this is the budget pick.

Best budget extra-firm: Majestic 9000 Extra Firm#

Hand-built by Luxe Mattresses, the Majestic 9000 delivers a 9.1 support score at £273 with a 100-night trial. For heavier front sleepers who wear out soft mattresses, it's the budget survivor; its deeper sibling, the Majestic 11000, adds a touch more cushioning for £318.

What each price band really buys#

Price (double)What to expectWatch out for
Under £120Simple foam, 15–18cm, fine for kids and guestsToo shallow for heavier nightly use
£120–£200Better covers (CoolMax, cashmere blends), 20–23cm coresShort or no home trial from some makers
£200–£300Brand-name entry models, long trials, firmer specialist buildsThin "lite" versions of famous names

What you can safely save on#

  • Brand name: small and direct-to-consumer makers often match big brands on materials for less.
  • Fancy covers and toppers: nice to have, not essential, a separate topper can be added later.
  • Pillow-top extras: a well-built medium core matters more than a plush surface that compresses.

What not to skimp on#

  • Support: a sagging core wrecks spinal alignment, prioritise firmness and core density over surface plushness.
  • Durability: long-term testing shows quality foams hold their firmness well, while cheap, low-density foam softens fast.2
  • Trial period: a home trial lets you return a mattress that doesn't suit, invaluable at the budget end.
  • Depth for your weight: over about 14 stone, treat 23cm as the minimum; a shallow core you compress flat supports nothing.

Value brands we rate#

  • The Foam People: made-to-order all-foam mattresses from around £109, with custom sizes and CoolMax options. The cheapest credible route to a supportive bed. See our Foam People review.
  • Luxe (Majestic range): hand-built British firm-foam models that drop into budget territory on sale, with a 100-night trial and 10-year warranty. See our Luxe review.
  • Emma (on sale): the popular bed-in-a-box rarely sells at full RRP, so its discounted price often lands in budget range with a long trial.

Is the "new mattress smell" a problem on cheap foam?#

Budget foam can have a faint odour out of the box. Independent testing of memory-foam emissions found volatile organic compounds well below health-based guidance values, decaying within weeks, so airing the mattress in a ventilated room for a day or two is generally enough.3

Frequently asked questions#

What is the best cheap mattress in the UK?#

For most buyers, the Westwood Memory Foam at £109 for guest rooms and lighter sleepers, or the Saffron Comfort Deep at £174 for nightly adult use.

How much do I need to spend on a decent mattress?#

From about £110 for occasional use, £150–£200 for a lighter adult sleeping on it nightly, and £200–£300 to get brand-name trials or specialist firmness. Above £300, see our main mattress guide.

Are cheap memory foam mattresses safe?#

Yes. Foam emissions testing found VOC levels well below health-based benchmarks, fading within weeks.3 Buy from a UK seller so fire-safety regulations apply, and air the mattress on arrival.

How long will a budget mattress last?#

Expect 4–6 years of nightly adult use from a sub-£200 foam build against 7–10 from a premium one. Rotating it monthly and using a protector extends its life.

Should I buy a used or ex-display mattress instead?#

No. Hygiene aside, a compressed second-hand core has lost the support you're buying it for, and you get no trial or warranty. A new £109 Westwood beats any used £500 mattress.

Is a budget mattress OK for a child?#

Often ideal: children are light, so a 15–18cm medium foam build supports them perfectly well, and they'll outgrow the bed before the mattress wears out.

The bottom line#

Buy for a medium-firm feel, a dense and supportive core, and a real home trial, and a cheap mattress can sleep far better than its price suggests. Browse our full range by price, filter by firmness, or take our quiz for a budget-matched pick.
