Layer Details
Pillowtop layer

Alpaca and wool layer
A layer of alpaca and wool for insulation and breathability. It helps you stay comfortable as the temperature changes.
Pocket spring core
2500 springs, each individually encased in a fabric pocket. Each spring works on its own, so support follows your body's shape.

Key benefits
- More room each: At 75cm per person, you get 7.5cm more each than on a UK double, which means fewer elbows and less negotiating over the middle.
- Less disturbance from your partner: The pocket springs work independently, so with a wider gap between you, a partner getting up early is less likely to wake you.
- Length for taller sleepers: The UK king is 10cm longer than the UK double, so feet that once hung off the end should now stay on the mattress.
- Space without a super king footprint: You gain width over a UK double, yet the UK king is 30cm narrower than the UK super king, which leaves more floor space in a modest bedroom.
- Springy cushioning across the full width: The mini spring pillow top responds as you move, so shifting position on the wider surface feels easy rather than like climbing out of a dip.
This size suits you if...
You share the bed every night and wake each other more than you'd like on a UK double, one of you is close to six foot and tired of cold feet, or your alarms go off hours apart and you want a bit more distance between you.
Consider another size if...
Your bedroom is under our suggested 2.7m x 2.9m, or 75cm each would still feel cramped. For a smaller room we'd recommend the UK double instead; for more width, the UK super king would suit you better.

FAQ's
Is the Relyon Lucia 2500 Pillow Top UK king big enough for two adults?
For most couples, yes. The UK king gives 75cm each for two sharing, which is 7.5cm more per person than the UK double. If you both sleep starfished or a child often joins you, the UK super king gives 90cm each, although it needs a bigger room.
Will a tall person fit on a Relyon Lucia 2500 king size mattress?
The UK king measures 150 x 200cm, or 5ft x 6ft 6in, so it is 10cm longer than the UK double. If one of you is around six foot, that extra length is often the real reason to upgrade, even more than the added width.
What size bedroom do I need for a UK king Relyon Lucia 2500?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable. In a new build master bedroom, measure after fitted wardrobes go in, because doors and drawers need clearance. At 37cm deep, this mattress also sits fairly high once it's on a base.
What duvet and sheets fit a Relyon Lucia 2500 Pillow Top king?
Standard king sheets and a 230 x 220cm king duvet fit the 150 x 200cm surface. The mattress is 37cm deep, so check the pocket depth of any fitted sheet before buying, as shallower king sheets may struggle to tuck under the corners.
Should I choose the Relyon Lucia 2500 in a UK king or UK super king?
The UK king is 30cm narrower than the UK super king and the same length, giving 15cm less each. If your room meets our suggested 3m x 2.9m and you want maximum separation, the UK super king suits. Otherwise the UK king is the sensible upgrade; compare the retailers listed on this page.
