Layer Details
- Comfort zones. Zoned areas designed to adjust the support across different parts of your body, which means your heavier areas can sink in slightly more than lighter ones. This helps keep your spine in a more natural position as you sleep.
- Standard foam. Polyurethane foam at 33 kg/m3 forms the supportive core of the mattress. This density gives the mattress its medium firm feel and its overall structure.
- Memory foam. A layer of memory foam that softens with your body heat and moulds to your shape. It adds a touch of pressure relief without making the mattress feel soft overall.

- A sensible depth for bunks and mid sleepers: At 20cm deep, it should sit below the guard rail on most bunk and cabin frames, though check your frame's maximum mattress depth first.
- Fits the smallest rooms: We suggest at least 2.1m x 2.8m of floor space, which means it works in box rooms, loft conversions and bedrooms where a desk and wardrobe compete for space.
- Supportive for growing sleepers: The medium firm feel and zoned foam core suit children and teens, who generally need steady support more than deep cushioning.
- An easy call for guest rooms: Two UK singles give a spare room more flexibility than one big bed, and the Akrehamn's simple foam build keeps that setup affordable.
- Light enough to live with: An all-foam single is far easier to rotate, move between rooms or carry up to a loft than a sprung double.
This size suits you if...
You're buying for a child or teenager moving up from a cot or toddler bed, you sleep alone and want to keep floor space free in a compact room, or you're kitting out a spare room, student room or first flat where the frame is already provided and takes a standard 90 x 190cm mattress.
Consider another size if...
You share the bed regularly, or you're a taller adult who finds 190cm restrictive. We'd recommend the UK double instead, which is 45cm wider and gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m of floor space.

Will the Ikea Akrehamn UK single fit a bunk bed or mid sleeper?
In most cases, yes. The UK single is the standard size for bunk, cabin and mid sleeper frames, and at 20cm deep the Akrehamn is slim enough to sit below the guard rail on most of them. Check your frame's stated maximum mattress depth before buying, as some children's frames cap it lower.
What size is the Akrehamn UK single in cm and feet?
It measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard UK single, so it fits standard single frames, divans and slatted bases, and takes standard single fitted sheets and a single duvet (135 x 200cm) without any hunting for odd bedding sizes.
Is the Akrehamn UK single a good mattress for a child or teenager?
It's a reasonable fit. The medium firm feel and zoned foam core give the steady support growing bodies need, and the simple design means there's little to go wrong. Lighter children may find it a little solid at first, since medium firm foam softens less under a low body weight.
How small a room will a UK single fit in?
We suggest at least 2.1m x 2.8m of floor space for a UK single, the smallest footprint of any standard adult size. That leaves room for a wardrobe, desk or toy storage in a typical box room, and its narrow width suits loft conversions where the bed tucks under the slope.
Can I put two Akrehamn UK singles in a guest room?
Yes, and it's a practical setup if your guests vary. Two UK singles side by side give solo visitors their own beds and can be pushed together for a couple. Each one needs 90 x 190cm plus a walkway between them, so measure the room before committing to two.
