Pocket springs
800 pocket springs individually react to your natural sleeping position, which means pressure is eased where you need it rather than across the whole surface. They're spread edge to edge, so you can use the full width of the mattress without a noticeable drop-off at the sides.

Key benefits

Key Benefits of the SleepSoul Balance 800 Single Mattress

  • Leaves space for everything else: At 90 x 190cm it sits comfortably alongside a desk and wardrobe in a small bedroom, and we suggest allowing at least 2.1m x 2.8m of floor space.
  • Usable right to the edge: The springs run edge to edge, which means a child or teen can use the full 90cm width without feeling the sides dip away beneath them.
  • A middle-ground feel for one: The medium tension suits most children and lighter adults, although a heavier adult who likes a firm surface may find it a little soft.
  • Separate beds for guests: Two UK singles let visitors who would rather not share a bed each have their own pocket spring mattress, so one guest turning over won't disturb the other.
  • Standard size for raised frames: The 90 x 190cm size matches standard UK single bunks and mid sleepers, but SleepSoul doesn't publish a depth, so check it against your frame's limit first.

Who should buy the SleepSoul Balance 800 Single Mattress?

This size suits you if...

You're buying for a child or teenager whose bedroom also has to hold a desk and wardrobe, or you're kitting out a study that doubles as a guest room and usually sleeps one visitor at a time.

Consider another size if...

You're an adult who sprawls across the bed or shares it with a partner. We'd recommend the UK small double instead, which is 30cm wider; allow at least 2.4m x 2.8m.

FAQ's

Frequently Asked Questions About the UK Single

Can I put the SleepSoul Balance 800 UK single on a mid sleeper or cabin bed?

The width and length match standard UK single raised frames. SleepSoul doesn't publish a depth for this mattress, though, and raised beds usually set a maximum mattress depth so the guard rail stays high enough. Check the brand's own guidance or ask the retailer before buying for a bunk, cabin or mid sleeper.

What size room do I need for a SleepSoul Balance 800 UK single?

We suggest 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 in a box room or a child's room where storage competes for the same floor.

Is the SleepSoul Balance 800 UK single big enough for an adult?

For one adult of average build who sleeps fairly still, 90cm is workable. If you're tall, bear in mind the UK single, UK small double and UK double are all the same length. Only the UK king adds length, and it is 10cm longer than the UK single.

How much narrower is the SleepSoul Balance 800 single than the double?

The UK single is 45cm narrower than the UK double, and the two are the same length. The UK double gives 67.5cm each for two people sharing, whereas the UK single is designed around one sleeper on its own 90cm.

Two SleepSoul Balance 800 singles or one double for a guest room?

Two UK singles give each guest their own 90cm mattress, which suits friends, siblings or visitors who wouldn't share a bed. A UK double gives 67.5cm each for two sharing and needs at least 2.6m x 2.8m. Remember to leave a walkway between two singles when planning the room.
