Silentnight Comfortable Foam Mattress
- Soft feel, light sleepers: Soft foam lets you sink in a little, which suits the lighter bodies most likely to be sleeping on a single: children, teenagers and smaller adults.
- Fits compact rooms: At 90cm wide, it leaves floor space for a desk, wardrobe and toy storage in a child's room, or two beds with a walkway between for siblings sharing.
- Modest room requirement: We suggest at least 2.1m x 2.8m of floor space, which most box rooms and loft conversions with a narrow footprint can manage.
- Simple to move: An all-foam single is light and forgiving to manoeuvre, useful for student rooms and first flats where the frame is provided and the mattress travels with you.
- Cheap, easy bedding: Single sheets and a 135 x 200cm single duvet are the most widely stocked and least expensive bedding of any UK size.
This size suits you if...
You're buying for a child or teenager moving up to a full-size bed, you're a lighter adult who sleeps on your side and likes a cushioned feel, or you're kitting out a spare room or study that occasionally hosts guests. It also suits tight spaces: a loft conversion, a shared children's room or a student flat where every centimetre of floor matters.
Consider another size if...
You're an adult who wants space to spread out, or two of you will ever share the bed. The UK single is 45cm narrower than the UK double, so we'd recommend the UK double instead; allow at least 2.6m x 2.8m of floor space for it.

Is the Silentnight Comfortable Foam Mattress in a UK single good for a child?
Yes, in most cases. The soft foam feel suits lighter bodies, and children and teens fall squarely into that group. The UK single is also the standard size for children's beds across the UK, so frames and bedding are easy to find. Heavier teenagers may eventually prefer something firmer as they grow.
Will the UK single Silentnight Comfortable Foam Mattress fit a bunk or mid sleeper frame?
The 90 x 190cm footprint matches standard UK bunk and mid sleeper frames, so width and length are fine. Raised frames often have a maximum mattress depth for safety rail clearance, and Silentnight doesn't publish a depth figure alongside this size in our listing, so check your frame's limit against the retailer's product details before buying.
Is a UK single big enough for an adult?
For one lighter adult, yes. At 90cm wide and 190cm long it's comfortable for solo sleeping, and this mattress's soft feel favours lighter side sleepers anyway. Taller adults, over about 6ft, may find their feet near the edge, since the UK single is 10cm shorter than the UK king.
How much floor space does a UK single mattress need?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single. That leaves room to walk around the bed and open drawers or wardrobe doors. It's a workable footprint for box rooms, lofts with sloping ceilings and children's rooms where the bed shares space with a desk and storage.
Is this a good mattress for a guest room single bed?
It's a reasonable fit. Guests use a spare bed occasionally, so a soft, budget-friendly foam single makes sense, and two UK singles suit rooms hosting couples and solo visitors alike. Frequent adult guests with heavier builds may find the soft feel offers less support than they'd like, so bear your usual visitors in mind.
