Compact bedrooms do not have to mean compromised comfort. The 20cm memory foam mattress in 4ft small double (120 x 190cm) brings a full-bodied foam build to a space-saving size.

Depth that makes a difference

Twenty centimetres of foam gives more to work with than slim alternatives, which means better pressure relief and a more luxurious feel. The 120cm width gives a single sleeper plenty of freedom and fits comfortably in smaller rooms.

Frequently Asked Questions

Will a 20cm memory foam mattress fit my 120 x 190cm small double frame?
It is made for 4ft small double frames measuring 120 x 190cm. Check the inside length and width of your bed before ordering. At 20cm deep it is a tall mattress for the size, so make sure your frame sides leave enough room.
Is a small double memory foam mattress right for a compact bedroom?
Yes, a 4ft small double gives more width than a single without taking up as much floor space as a standard double. It is ideal for box rooms, guest rooms, and anyone who sleeps alone but likes to stretch out.
How does memory foam differ from an ordinary foam mattress?
A standard foam mattress tends to spring back straight away, whereas memory foam responds slowly to heat and pressure. It gradually moulds to your outline, giving a cushioned feel that many people find relaxing and quiet to sleep on.
What firmness can I expect from this 20cm small double?
It is not listed as medium firm or orthopaedic, so expect a comfort-led, contouring feel with a deep layer of foam. If you want a flatter, firmer feel, our medium firm small double options will suit you better.
Can a thick foam mattress feel warm, and what helps?
Yes, a deep memory foam mattress can hold body heat, and it is not sold as cooling. Using breathable cotton bedding, keeping the room ventilated and avoiding heavy duvets on warm nights can make it feel more comfortable.
What difference does 20cm of depth make to comfort?
More foam depth generally means a plusher, more cushioned feel and a taller bed. At 20cm this mattress has a substantial presence, so use fitted sheets with a deep pocket and check the height against your headboard.
What bedding size is right for a 4ft small double?
Buy small double bedding made for 120cm-wide beds. Because the mattress is 20cm deep, choose a fitted sheet with a pocket depth of 25cm or more. Standard double sheets are normally too large and can look baggy.
How long should a rolled foam mattress be left before use?
Leave it unwrapped and flat for around 24 hours so the foam can expand to full depth. It usually arrives compressed in a box, which makes it easy to move. Air the room to help any slight new-foam smell fade.
How should I care for this memory foam mattress day to day?
Rotate it head to foot every few months and keep it on a firm, ventilated base. Let it breathe when you change the bedding, and spot clean marks with a lightly damp cloth rather than soaking the foam.
Does a memory foam mattress suit me better than a hybrid small double?
If you like a sink-in, cushioned feel, a memory foam mattress is a good fit. If you prefer a bouncier, more open feel, a hybrid or pocket sprung small double may suit you better. Comfort is personal, so consider both before you decide.
