Layer Details
Pillow-top
A soft pillow-top with plush fillings sits at the surface. It adds an extra layer of cushioning under your shoulders and hips, so the mattress feels softer to lie on than the medium firmness alone suggests.
800 pocket springs
Below the pillow-top, 800 pocket springs conform to your body and support you where you need it most. Because each spring works on its own, the mattress follows your shape rather than moving as one block.

Key benefits
- Fits standard single frames: At 90 x 190cm, the UK single matches the frame most children's beds, cabin beds and spare room divans are built around, so you're rarely hunting for an odd size.
- Space left for everything else: A narrow 3ft width means the bed doesn't crowd out the toy boxes, desk and wardrobe that a child's room usually has to hold as well.
- Proper springs for a growing body: Each of the 800 pocket springs responds on its own, which means a child or teenager gets support that follows their shape rather than sagging into one dip.
- Two beds in a guest room: If your spare room needs to sleep two friends or siblings separately, a pair of UK singles with a walkway between them often suits the space better than one bigger bed.
- Easy to replace in a student let: Student rooms and first flats often come with a single frame but no mattress, and a UK single slots straight onto it.
This size suits you if...
You sleep alone and want pocket springs without giving up floor space, you're kitting out a child's or teenager's room, or you're furnishing a spare room or office that needs a guest bed with room for a desk alongside it.
Consider another size if...
You're an adult who sprawls, or a child is about to outgrow a narrow bed. We'd recommend the UK small double instead: it's 30cm wider at the same length, and we suggest at least 2.4m x 2.8m for it.

FAQ's
Will the SleepSoul Bliss 800 UK single fit a bunk bed or mid sleeper?
The 90 x 190cm footprint matches standard single bunk and mid sleeper frames. SleepSoul doesn't publish a depth for this mattress, though, and raised frames usually set a maximum mattress height so the guard rail stays effective. Check the frame maker's limit and confirm the depth with the retailer before buying for a top bunk.
How small a bedroom can take a Bliss 800 single?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single, which gives you room to walk around the bed and open drawers. That makes it a sensible fit for box rooms and loft conversions where a wider bed would leave very little clear floor.
Is the SleepSoul Bliss 800 single a good mattress for a child or teenager?
The 800 pocket springs move independently, which means a growing body gets support that adjusts to it rather than a sagging middle. SleepSoul doesn't state a firmness, so if your teenager has a clear preference for soft or firm, you'll be buying with less information than some parents would like.
Should an adult choose the UK single or UK small double Bliss 800?
A UK single suits an adult who sleeps fairly still and needs to save space. If you turn a lot or like room to spread out, the UK small double is 30cm wider at the same length, and we suggest at least 2.4m x 2.8m of floor space for it.
Do pocket springs matter on a single mattress for one sleeper?
You lose the main shared-bed benefit, since there's no partner's movement to absorb. The springs still help, though: each one responds to the part of the body above it, which means shoulders and hips sink slightly while the lower back stays supported, a useful trait for a solo side sleeper.
