Slim mattresses have their place, and the 11cm medium firm memory foam mattress in 4ft small double (120 x 190cm) is a good example. It is light, easy to handle and suits bed frames where deeper mattresses would sit too high.

Where a slim profile makes sense

Think cabin beds, mid-sleepers, caravans, holiday lets and guest rooms. An 11cm depth keeps the sleeping height low and safety rails effective, and it comes at a lower price than deep foam builds.

Frequently asked questions

Is 11cm enough for nightly use?

It can work, but slimmer mattresses offer less cushioning than deep ones. Light sleepers and guests are usually happiest.

Will it suit a cabin bed?

Slim mattresses often do, but always check the bed's maximum mattress depth.

What does medium firm mean?

A balanced feel: supportive with a gentle give.

Is it easy to move?

Its low depth makes it lighter and easier to carry than thick mattresses.

Should I add a topper?

A mattress protector is useful for keeping it clean; choose any extras carefully so the overall depth stays within your frame's limits.

Frequently Asked Questions

Does this 11cm medium firm mattress fit a 4ft small double frame?
It is cut for the 4ft small double size of 120 x 190cm. Measure the inside of your frame before ordering to confirm. At 11cm deep it is a slim mattress, so it sits low and suits frames with tall sides.
Who suits a slim medium firm small double memory foam mattress?
It suits a guest room, a child or teenager moving up from a single, or an adult who wants a lower, steadier bed. A small double memory foam mattress at this depth is a practical, space-saving option.
What do I get from memory foam in a slimmer mattress?
You still get foam that softens with body heat and shapes itself around you. A slimmer build means less foam depth, so the cushioning feels more compact than a deeper mattress, while the medium firm feel adds stability.
How firm is a medium firm memory foam mattress at 11cm?
Medium firm feels supportive with a gentle layer of contouring on top. With only 11cm of depth, it will feel more compact than a thick plush mattress, so it suits people who dislike sinking into very deep foam.
Will a thinner foam mattress sleep warm?
Less foam can mean less heat build-up than a deep mattress, but memory foam still holds some warmth compared with sprung designs. This one is not sold as cooling, so use breathable bedding and keep the room airy.
Is 11cm deep enough for regular sleeping?
11cm is a slim depth that works well for lighter use, spare rooms and frames where you need a low profile. For everyday main-bed comfort, many people prefer deeper foam, so decide based on how often it will be used.
Which sheets suit a 4ft small double mattress?
Choose small double bedding labelled for 4ft or 120cm beds. A slim 11cm mattress works with standard-depth fitted sheets, so you do not need extra-deep ones. Standard double sheets are usually too big and can bunch.
How is a slim foam mattress packed and how long does it take to expand?
It will normally arrive rolled in a box. Unpack it in the bedroom, lay it flat and allow around 24 hours for the foam to take its shape. Open a window to help any slight smell clear faster.
How do I keep a thin foam mattress fresh and even?
Rotate it head to foot every few months and keep the base ventilated. Wipe marks with a lightly damp cloth and let the surface dry fully. Avoid soaking, which foam does not like and which can affect its feel.
Should I buy a slim foam mattress or a deeper pocket sprung one?
A slim memory foam mattress is lighter and easier to handle, which suits spare beds and low frames. A deeper pocket sprung or hybrid mattress usually feels bouncier and more substantial for everyday use in the main bedroom.
