Layer Details
TEMPUR Adapt Memory Foam
A 3cm top layer with ultra sensitive cells that shape to your body and respond to your weight and temperature, which means a gradual, cradling sink rather than an instant one. This is the layer that gives Tempur its distinctive slow-response feel.
Memory Foam
An 8cm layer that absorbs motion as you move during the night. In practice, that means less partner disturbance when one of you turns over or gets up.
High Density Foam
A 9cm base layer that creates a solid, sturdy foundation for the softer foams above. It's what keeps the mattress feeling supportive edge to edge rather than saggy.

Key benefits
- Leaves room for everything else: At 3ft x 6ft 3in, the UK single leaves space for a desk, wardrobe and toy storage in a child's bedroom, which means the bed doesn't take over the room.
- Two beds side by side: The narrow footprint lets you fit a pair of UK singles in a shared children's room or a guest room, with a walkway left between them.
- Slimmer profile for raised frames: At 20cm deep it's shallower than some rivals, which may help on a cabin or mid sleeper, although you should check the frame's maximum mattress depth first.
- Pressure relief for one: The 3cm Adapt foam top layer moulds slowly to hips and shoulders, which means a solo side sleeper feels pressure spread more evenly through the night.
- Firm enough for a lighter body?: The medium firm feel may seem a little firm to young children and light adults, but it offers steady support as a teenager grows.
- Fits a loft conversion: A UK single slots under a sloping ceiling where a wider bed won't, so one sleeper gets Tempur's feel in an awkward attic room.
This size suits you if...
You sleep alone and want memory foam pressure relief in a small bedroom, or you're furnishing a child's room, a teenager's room or a spare room that also has to hold a desk. It also suits a guest room where you'd rather fit two separate beds than one large one.
Consider another size if...
You share the bed with a partner, or you're tall and find 190cm long feels short. For couples, we'd recommend the UK double instead, which gives 67.5cm each; we suggest at least 2.6m x 2.8m for it.

FAQ's
Will the Tempur Ease UK single fit a bunk bed or cabin bed?
The Tempur Ease is 20cm deep. Many raised frames set a maximum mattress depth so the guard rail stays high enough above the sleeping surface, so check the frame maker's own guidance before buying. The UK single's 90 x 190cm dimensions match the standard UK single frame size.
What size bedroom do I need for a Tempur Ease UK single?
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, which matters most in a child's room or a box room that also holds a desk.
Is a UK single Tempur Ease big enough for an adult?
For most solo adults, yes. It measures 90 x 190cm, or 3ft x 6ft 3in. Taller sleepers may find the length a little short, and the UK king is 10cm longer, although it's also a much wider bed and needs at least 2.7m x 2.9m of floor space.
What bedding fits a Tempur Ease single mattress?
Standard UK single sheets and a single duvet (135 x 200cm) fit the UK single. With the mattress at 20cm deep, check that your fitted sheet's pocket depth covers it, so the corners stay put.
Should I buy a Tempur Ease UK single or UK double for a teenager?
If the bedroom is compact, the UK single keeps floor space free for a desk and storage. The UK double is 45cm wider, which gives a growing teenager more room to spread out, but we suggest at least 2.6m x 2.8m for it, against 2.1m x 2.8m for the UK single.
