Layer Details
Sealy medium foam
A top layer of Sealy medium foam, described as soft yet supportive. It takes the edge off the firm rating so the surface feels a little more welcoming when you lie down.
MemoryFlex comfort layer
A full layer of MemoryFlex that adapts to your body shape. It gives pressure relief, so your shoulders and hips are cushioned rather than pushed back against.
MemorySense ComfortCore
A core that focuses on heavier areas like the hips and lower back. That means support is tailored to where your body needs it most.

Key benefits
- Leaves space in a small room: We suggest allowing at least 2.1m x 2.8m for the UK single, which leaves room for a desk, wardrobe or toy storage in a box room.
- Firm support for older children: The MemorySense ComfortCore focuses support on the hips and lower back, which means a teenager who sleeps on their back stays well supported as they grow.
- Cool cover for tucked-away rooms: The SmarTex Plus cover is cool to the touch, which helps in a loft conversion or small bedroom where the air can feel close on summer nights.
- Allergen treatment for children and guests: The ProShield allergen treatment is endorsed by Allergy UK, which is reassuring for a child's bed or a guest bed used by visitors whose allergies you may not know.
- Two beds where one double would go: At 3ft x 6ft 3in, a pair of UK singles gives two guests or two siblings a bed each, with the option of a walkway between them.
This size suits you if...
You sleep alone and like a firm, supportive bed but have limited floor space, or you're furnishing a teenager's bedroom or a guest room that needs two separate beds rather than one shared one.
Consider another size if...
You share the bed with a partner every night. For two people, we'd recommend the UK double instead, which gives 67.5cm each; we suggest at least 2.6m x 2.8m for the UK double.

FAQ's
Will the Sealy Elevate Ultra Daito UK single fit a bunk bed or mid sleeper?
Check the frame first. The mattress is 31cm deep, which is deep for a raised frame, and bunk, cabin and mid sleeper makers usually set a maximum mattress depth so the guard rail stays high enough above the sleeper. Compare 31cm with the figure the frame maker gives; if theirs is lower, this mattress isn't suitable for that bed.
Is the Sealy Elevate Ultra Daito single too firm for a child?
It may be for a light child who sleeps on their side. Sealy rates it firm, and lighter side sleepers can feel pressure at the shoulders and hips even with the medium foam on top. An older child or teenager who sleeps on their back is a better match for this firm feel.
What size is a Sealy Elevate Ultra Daito single in feet?
The UK single measures 3ft x 6ft 3in, or 90 x 190cm. That is the standard UK single, so it fits standard single bed frames, divan bases and single bedding without any special sizing.
What room size do I need for a UK single Sealy Elevate Ultra Daito?
We suggest at least 2.1m x 2.8m of floor space for a UK single. That allows room to get in and out of bed and open a wardrobe door. If you're fitting two singles for siblings or guests, plan for both beds plus a clear walkway between them.
Is the UK single Sealy Elevate Ultra Daito long enough for a tall adult?
The UK single is 190cm long, the same length as the UK double. If you need extra length, the UK king and UK super king are both 10cm longer than the UK single, though much wider; we suggest at least 2.7m x 2.9m for the UK king.
