What size is a small double mattress?

A small double mattress measures 120cm wide and 190cm long. In imperial measurements, that's 4 feet wide, 6 feet and 3 inches long (4' x 6'3"). Small double mattresses are the same length as double mattresses, but approximately 15cm (6 inches) narrower.

Can a small double mattress fit two adults?

Yes, a small double mattress can fit two adults - but it will feel very cosy. We recommend double or king size mattresses instead, which will give you both enough space to sleep without disturbing each other. Small double mattresses are best for one adult, or occasional use by two adults. They're also a good option for smaller bedrooms.

Do you have small double mattress toppers?

Yes, we have a great selection of small double mattress toppers, including memory foam mattress toppers. They're a great way to give your existing mattress a new lease of life and provide a little extra comfort.

Can a small double mattress fit on a double bed?

Technically, a small double mattress can fit on a double bed - but we don't recommend this! This will create gaps in-between your mattress and bed, which could be a safety hazard. Placing your mattress on an unsuitable bed may also invalidate your warranty. The best option is to choose a small double bed with mattress as one complete bed and mattress set, to be sure of a good fit.
