Layer Details
- Pillow-top layer. A soft pillow top of plush filling sits on the surface. This gives extra cushioning before you reach the firmer layers below.
- Soft foam. A 5cm layer of soft foam adds a cushioned feel. It works with the pillow top to soften that firm overall rating.
- Memory foam. This 3cm layer contours to your shape, which means pressure points are relieved as you settle in. It also acts as a transition layer, giving a controlled sink and minimising movement.
- Hard foam. A 2cm hard foam layer distributes your weight consistently. It bridges the softer comfort layers and the springs beneath.
- Pocket springs. 1500 individual pocket springs conform to your body, supporting you where you need it most. Because each spring moves on its own, the design helps prevent the roll-together effect with a partner.
- Base. A non-slip fabric base keeps the mattress steady on your bed frame. A small detail, but it stops the annoying gradual slide.

- Space left for everything else: We suggest a room of at least 2.1m x 2.8m, which means a desk, wardrobe and toy storage can still share a small bedroom with the bed.
- Two singles for guests: Two UK singles side by side let friends or siblings who'd rather not share sleep separately, each on their own set of independent pocket springs.
- Firm support, softer surface: The pillow top cushions you as you lie down while the firm spring core does the supporting, which suits a teenager or adult who prefers a firmer bed alone.
- Stays put on slatted frames: A non-slip fabric base stops the mattress creeping, which is useful on a cabin bed or daybed where a slowly sliding mattress becomes a real nuisance.
This size suits you if...
You sleep alone and want firm support with a cushioned top, or you're kitting out a child's room, student let or spare room where floor space matters more than width.
Consider another size if...
You want more room to spread out than 90cm allows, or a partner sometimes joins you. We'd recommend the UK small double instead: 30cm wider, same length, and we suggest at least 2.4m x 2.8m.

What size room do I need for a SleepSoul Bliss 1500 UK single?
We suggest allowing at least 2.1m x 2.8m. That's our own guidance rather than SleepSoul's, and it leaves space to walk around a 90 x 190cm bed with a bedside table. In a loft conversion, a 3ft width is often narrow enough to tuck under the slope, although check the headroom where you'll sit up.
Can the SleepSoul Bliss 1500 single go on a mid sleeper or cabin bed?
Check the frame first. This mattress is 31cm deep, and raised frames usually set a maximum mattress depth so the guard rail stays high enough to do its job. If your frame's guidance is below 31cm, this mattress isn't the right pick for it, however well the single dimensions fit.
UK single or UK small double: which SleepSoul Bliss 1500 should I buy?
The UK small double is 30cm wider but the same length, so a solo adult gets room to sprawl without needing a longer room. It takes more floor, though: we suggest at least 2.4m x 2.8m, against 2.1m x 2.8m for the UK single. In a child's room, the single usually leaves more space for storage.
Is a UK single SleepSoul Bliss 1500 long enough for a tall teenager?
It's 190cm long, or 6ft 3in. If your teenager is already close to that, their feet may reach the end. The UK king is 10cm longer, but it's also 60cm wider and we suggest at least 2.7m x 2.9m for it. If the room can't take that, measure your teen before ordering.
Is the SleepSoul Bliss 1500 in a UK single a good guest bed?
In a spare room that doubles as an office, one single keeps the desk clear. Two singles let you host guests who'd rather sleep apart. Bear in mind the feel is firm, so lightweight side sleepers staying over may find it a little unyielding, even with the pillow top softening the surface.
