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.

- More room each: You get 75cm each, which is 7.5cm more per person than the UK double, enough that an elbow or knee is less likely to land on your partner.
- Quieter early starts: The pocket springs move on their own, so when one of you gets up hours before the other, the sleeper left behind should feel a little less of it.
- Length for taller sleepers: At 200cm the UK king is 10cm longer than the UK double, which means feet stay on the mattress for anyone over six foot.
- Firm support across a wider surface: The firm spring core supports both halves of the bed, while the pillow top and memory foam soften the surface at your hips and shoulders.
- Space for pillows and repositioning: The extra width helps during pregnancy or recovery, when one partner needs support pillows and frequent position changes without crowding the other.
This size suits you if...
You share the bed every night and have outgrown a double, one of you is tall enough that a 190cm mattress leaves your feet hanging, or you and your partner keep different hours and want the early riser to disturb the other a little less.
Consider another size if...
Your bedroom is under our suggested 2.7m x 2.9m. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

Is a UK king SleepSoul Bliss 1500 big enough for two adults?
Yes, for most couples. The UK king gives 75cm each for two people sharing, which is 7.5cm more each than the UK double. If you both sprawl, or a dog regularly joins you, the UK super king gives 90cm each, although it needs a larger room.
Will a tall person fit on the SleepSoul Bliss 1500 king size?
The UK king is 200cm long, 10cm longer than the UK double, the UK small double and the UK single. If one of you is over six foot, that extra length is often the bigger improvement, because you are less likely to sleep with your feet over the edge.
Does the SleepSoul Bliss 1500 king reduce partner disturbance?
It should help. The 1500 pocket springs move independently, so movement on one side travels less to the other, and the memory foam gives a controlled sink. Add the 75cm each that the UK king provides and there is more space between you, which suits couples who go to bed or get up at different times.
What room size do I need for a SleepSoul Bliss 1500 UK king?
We suggest allowing at least 2.7m x 2.9m, with 3.2m x 3.2m comfortable. Measure after the wardrobes and drawers are in, because a new build master bedroom can feel smaller once furniture takes up floor space. If you have less room than our minimum, the UK double needs at least 2.6m x 2.8m.
Should I get the SleepSoul Bliss 1500 in a king or super king?
The UK king suits most couples. It is 30cm narrower than the UK super king but the same length, and gives 15cm less each. The UK super king makes sense if you want maximum personal space and have at least 3m x 2.9m of room. Otherwise, the UK king is the easier fit for a typical bedroom.
