A 3cm responsive memory foam layer provides body-moulding comfort and support, while alleviating pressure across your shoulders, hips and lower back.

Reasons to buy
+Extremely cheap +Comfortable but firm+Great support

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.
