Small rooms still deserve proper support. The 20cm orthopaedic memory foam mattress in 4ft small double (120 x 190cm) concentrates firm, spine-friendly comfort into a space-saving size.

Support in a smaller footprint

This size works well in box rooms and flats where a full double would swamp the space. Twenty centimetres of foam gives the mattress good body, while the orthopaedic styling keeps the feel supportive rather than overly soft.

Frequently Asked Questions

Does this 20cm orthopaedic mattress fit a 4ft small double frame?
It is made for the 4ft small double size of 120 x 190cm. Measure the inside of your frame to confirm. At 20cm deep it is a well-padded mattress, so check your headboard and side rails for height.
Who would pick an orthopaedic small double memory foam mattress?
It suits solo sleepers who want extra width and a firmer, supportive feel, and anyone furnishing a spare room with a dependable bed. Small double memory foam mattress shoppers who dislike very soft beds often like this style.
What does orthopaedic mean for this foam mattress?
In mattress shopping, orthopaedic simply describes a firm, supportive style. Think of it as a firmer alternative to a soft, plush memory foam mattress, with a layer of foam on top for gentle comfort. At 20cm deep, check your frame sides and headboard height before ordering.
How firm does a 20cm orthopaedic foam mattress feel?
Expect a firmer, more supportive surface than a soft foam bed, with a layer of foam on top for gentle comfort. The 20cm depth adds cushioning without making it feel like you sink in. Personal preference still varies.
Will a firm foam mattress sleep warm?
Memory foam can retain body heat, though a firmer feel means you rest more on top of the surface. It is not sold as cooling, so light bedding, a ventilated room and breathable sheets are still sensible.
What does 20cm depth give a small double mattress?
A 20cm depth gives a generous, comfortable layer of foam and a solid presence on the bed. It is deeper than many guest mattresses, so choose fitted sheets with a deep pocket to wrap it securely.
What sheets do I need for a 4ft small double that is 20cm deep?
Buy small double bedding made for 120cm-wide beds, with a fitted sheet pocket depth of at least 25cm. Standard double sheets are usually too wide and will bunch, which can feel untidy and uncomfortable.
What is the unboxing process for a rolled orthopaedic mattress?
It usually arrives compressed and rolled in a box. Take it to the bedroom, remove the wrapping and let it expand for about 24 hours. Open a window to help any slight new-foam smell disperse.
How do I keep a firm foam mattress comfortable for years?
Rotate it head to foot every few months, keep it on a ventilated base and spot clean spills with a lightly damp cloth. Avoid soaking and avoid sitting on one edge constantly, which can wear that area faster.
Should I buy a firm foam small double or a pocket sprung one?
Firm memory foam is quiet and gently contouring, while pocket sprung mattresses feel bouncier and more open. A hybrid sits between the two. Choose the feel you prefer, and consider room size and how warm you sleep.
