7 of the best cheap mattresses you can buy

The Silentnight Pocket Essentials 1000 is the best cheap mattress you can buy. It’s fantastic value, giving you a luxurious 1000 Mirapocket spring system and soft knit cover for a ridiculously low price. It’s also extremely comfortable: each spring is able to pivot in its own pocket, allowing the mattress to provide better support by moulding to your body shape, and preventing motion transference – so you won’t be disturbed by a tossing and turning partner. And as you’d expect from a globally respected brand like Silentnight, it comes on a durable, hypoallergenic case. You’ll find hundreds of rave reviews for the Silentnight Pocket Essentials 1000 – and if you buy it from Silentnight direct, you’ll get a 60-night trial. We’d recommend checking Amazon first though: right now, the price has been slashed by over 30 per cent. 

Can a memory foam mattress this cheap be worth buying? We think so. With a Which? Best Buy award and hundreds of happy reviews online, the Silentnight 3 Zone Memory Foam mattress does a great job of helping your body keep a natural position. A 3cm responsive memory foam layer provides body-moulding comfort and support, while alleviating pressure across your shoulders, hips and lower back. It's also anti-allergy, and although it might smell a bit when you first open it, that’s normal – it’s just the fresh foam, and will disappear after a few days. This mattress isn’t as thick as the pocket sprung option at number one in this list, but like Pocket Essentials model, it’s been designed to reduce motion transfer, so you won’t be bothered by a partner tossing and turning. This is a fantastic budget mattress, and one of the best cheap memory foam mattresses you can buy.

If you can increase your budget a little, this cheap hybrid mattress from Happy Beds is outrageously good value. The Bamboo Vitality boasts a luxurious 2000 pocket springs to support you, plus 5cm of body contouring memory foam and another 5xcm of reflex foam. It’s non-flip, with hand-stitched borders and side air vents for breathability, and has received rave reviews on Amazon – where the Bamboo Vitality is on sale for almost half its RRP, coming it at £234.99 for a single, £289.99 for a double and £329.99 for a king. Bargain. 

The Ikea Morgedal is a thick foam mattress in a polyester wrapping. Don’t expect lots of high-tech layers or cutting edge tech: this brilliant budget mattress is exactly what you’d expect from a big lump of foam: comfortable and fairly immune to the movements of your partner. it comes with a 90-day trial period, and it's won a Best Buy award from Which? as well, so you know you’re in good hands despite its distinct lack of bells and whistles.

The Happy Beds Signature Platinum 2000 Pocket Sprung Orthopaedic Mattress has dropped in price since its release. Thanks to a mattress sale at Happy Beds itself (which is currently offering almost 50 per cent off its RRP), as well as sales at retailers like Amazon (which is showing similar prices), this popular pocket spring mattress is astoundingly cheap compared to rival mattresses. For a bit more money, you get twice as many pocket springs as the Silentnight Pocket Essentials 1000 - our best cheap mattress – which means even more support, and a level of luxury that’s unusual for a budget mattress. 

The Nytex 7 Zone Memory Foam Mattress is a fantastic cheap foam mattress - and it comes with a free 60-night trial, so you can really test whether it’s right for you. It’s 2cm thicker than the Silentnight 3 Zone Memory Foam mattress at number two on this list, and Nytex says it features the same 50KG/m3 memory foam as that used in many premium brand mattresses too. Certainly it’s received a host of glowing reviews online. If you’re in the market for a cheap memory foam mattress and want an alternative to the Silentnight above, this one is worth a look.

As a rule, we don’t normally recommend open coil mattresses because they tend to give a less good night’s sleep. Happy Beds’ Super Orthopaedic Open Coil Spring mattress is the exception to the rule though, with almost 1,000 great reviews on Amazon. A thick layer of sturdy reflex foam sits on a strong network of traditional open coil springs, providing a firm level of support that Happy Beds says is “perfect for those seeking orthopaedic assistance”. We’re can’t guarantee this aspect – but at around £150 for a double on Amazon at the moment, this is easily one of the best cheap mattresses you can buy.
