Memory foam comfort layer
A deep memory foam comfort layer moulds to your body to relieve pressure. In practice that means a slow, cradling feel that eases weight away from your hips and shoulders.

Key benefits
- More room each: At 75cm per person, you each get 7.5cm more than on a UK double, which means a little more distance between you when one partner turns over.
- Length for taller sleepers: The UK king runs to 200cm, 10cm longer than a UK double, so a partner approaching 6ft can stretch out without their heels resting on the edge.
- Easier on staggered alarms: If one of you rises hours earlier, the extra width gives them their own side to slip out of, with slightly less chance of waking the other.
- Space for support pillows: During pregnancy, the memory foam eases pressure on hips and shoulders, while the UK king leaves room for a bump pillow without squeezing your partner towards the edge.
- A cooler way to share foam: Yes, all-foam mattresses can hold warmth, but the UK king lets you sleep further apart, and the Tencel cover helps draw moisture away.
This size suits you if...
You share the bed every night and feel cramped on a UK double, one of you is approaching 6ft and needs the extra length, or your schedules differ and you would like a bit more space between you in the early hours.
Consider another size if...
Your bedroom is under our suggested minimum of 2.7m x 2.9m for a UK king. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Is the Sleep Story Memory Plus UK king long enough for someone over 6ft?
The UK king is 200cm long, 10cm longer than the UK double, UK small double and UK single. That extra length is a relief for anyone approaching 6ft. The UK super king is the same length, so sizing up beyond the UK king gains you width but no more legroom.
Memory Plus UK king or UK super king for a couple?
The UK king gives you 75cm each, while the UK super king gives 90cm each, 15cm more per person. Both are 200cm long. The catch is floor space: we suggest at least 2.7m x 2.9m for the UK king and at least 3m x 2.9m for the UK super king.
Will a Sleep Story Memory Plus king fit in a new build master bedroom?
Allow at least 2.7m x 2.9m, with 3.2m x 3.2m giving comfortable space to walk around. New build master bedrooms often feel smaller once fitted wardrobes are in, so measure the clear floor that remains, not the room plan, before choosing the UK king.
Is the Memory Plus in a UK king a good choice during pregnancy?
The UK king gives you 75cm each, enough to bank pillows around a bump while your partner keeps their side. The medium memory foam moulds to relieve pressure on hips and shoulders. If you run warm, bear in mind all-foam mattresses can hold heat more than sprung ones.
How much more space is a UK king Memory Plus than my current double?
Moving from a UK double to the UK king adds 15cm of width and 10cm of length. Shared between two, that works out at 75cm each instead of 67.5cm, so 7.5cm more per person. It is a modest gain on paper, but one you notice at night.
