Layer Details
AlignSupport Coil system
A patented, twice-tempered coil with a UniCased edge. It gives deep-down support and a supportive edge, so the mattress stays stable when you sit or sleep near the side.
MemorySense ComfortCore
A comfort core positioned to support the hips and lower back for pressure relief. You get a little cushioning where your body presses down most.
Extra firm foam
A double layer of extra firm foam sits alongside the ComfortCore. It keeps the surface flat and firm, with very little sink.

Key benefits
- Leaves room for the rest of the furniture: At 90 x 190cm (3ft x 6ft 3in), it leaves space for a desk or wardrobe, and we suggest allowing at least 2.1m x 2.8m of floor.
- Supportive sides on a narrow bed: The UniCased edge firms up the sides, which means you can sleep close to the edge of a 90cm-wide bed without feeling you might roll off.
- Flat support for a solo back sleeper: The double layer of extra firm foam keeps the surface level, so a back sleeper who dislikes sinking gets even support with nobody else's weight shifting it.
- Some cushioning where it is needed: The MemorySense ComfortCore sits under the hips and lower back, giving a little pressure relief in the area a single sleeper presses down on most.
- Allergen protection in a child's or guest room: ProShield allergen protection is endorsed by Allergy UK, which is reassuring for a spare room that gets aired rarely or a teenager prone to dust allergies.
This size suits you if...
You sleep alone and mostly on your back, preferring a flat feel with very little sink, or you're furnishing a teenager's bedroom or a spare room that has to fit a desk and wardrobe alongside the bed.
Consider another size if...
You share the bed with a partner, or a child or dog regularly joins you. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m.

FAQ's
Will the Sealy Elevate Hagen UK single fit a bunk bed or mid sleeper?
It matches the standard 90 x 190cm footprint, but it is 28cm deep, which is thick for many raised frames. Check the frame maker's maximum mattress depth before buying, because the safety rail needs to stay well above the sleeping surface on a bunk, cabin or mid sleeper bed.
Is an extra firm UK single mattress suitable for a child?
It depends on the child. Sealy rates it extra firm, so there's very little give, and lighter sleepers who lie on their side may find it uncomfortable at the shoulders and hips. An older child or teenager who sleeps on their back is the better match.
What size room do I need for a UK single Sealy Elevate Hagen?
We suggest at least 2.1m x 2.8m of floor space. That leaves a walkway beside the bed and room for a wardrobe or desk, which helps in a box room or a loft conversion where the usable floor is narrow.
What sheets and duvet fit the Sealy Elevate Hagen single?
Standard single sheets fit the 90 x 190cm surface, and a single duvet (135 x 200cm) covers it. Because the mattress is 28cm deep, choose a fitted sheet with a deep pocket so the corners don't keep pinging off.
Is a UK single long enough for a tall teenager?
The UK single is 190cm long, the same as the UK double. If your teenager is already very tall, the UK king is 10cm longer than the UK single, although it needs a much bigger room: we suggest at least 2.7m x 2.9m.
