Frequently Asked Questions
What size is a small double mattress?
A small double (4ft) is about 120 x 190cm, 15cm narrower than a standard 4ft6 double. This 18cm hybrid is made for that size and fits any 4ft small double frame or divan.
Is a small double big enough for two people?
It can work for occasional sharing, but at 120cm most couples will be more comfortable on a 4ft6 double or king. It is ideal for one adult who wants extra room.
How deep is an 18cm mattress and is it comfortable?
18cm is a slimmer, lighter build. It suits spare rooms and lighter sleepers, while nightly use by heavier sleepers may call for a deeper hybrid. Check your frame sides and headboard before ordering, and compare deeper small double mattresses if you want a plusher feel.
What is a hybrid small double mattress?
It combines a spring base with foam comfort layers, giving support from the springs and cushioning from the foam in a compact 4ft size. The springs also let air move through the mattress, so it usually feels more breathable than all foam.
How firm is it?
It has a medium feel, supportive underneath with a softer top layer, which suits most back, side and combination sleepers. Comfort is personal, so if you prefer a firmer or plusher feel, compare other small double mattresses in our range.
What bedding fits a 4ft mattress?
Use small double (4ft) fitted sheets, made for about 120 x 190cm mattresses. Standard double sheets are too wide and can bunch up. Check the pocket depth on the label against the 18cm mattress so the corners stay snug.
Does it sleep warm?
The spring core leaves gaps for air to move, so it generally sleeps cooler than an all-foam mattress, although bedding and room temperature matter too. Breathable bedding and a ventilated room help if you tend to sleep warm.
Is it a budget small double mattress?
It is a value-priced hybrid. For the lowest prices, browse our cheap mattresses collection. Compare depth, firmness and construction as well as price, so you choose a small double that suits your bed and how it will be used.
How should I care for it?
Rotate head to foot every few months, air the room regularly and keep it on a supportive, ventilated base. Spot clean spills with a damp cloth and mild soap, and allow the mattress to dry fully before making the bed. Avoid soaking it.
How long will it last?
With regular rotation and a supportive base, several years. Replace it once it sags noticeably or stops feeling supportive. How long it lasts depends on use, sleeper weight and care, so take this as a general guide rather than a guarantee.
