Layer Details
Euro pillowtop
A deep, quilted Euro pillowtop that adds an extra layer of ultra-cushioned comfort. It gives the surface a soft, plush feel when you first lie down.
Geltex comfort layer
Geltex is a gel-infused foam that increases comfort and body support. It sits under the pillowtop to add support beneath the soft surface.
Pocket spring support
Pocket springs are mounted in their own separate fabric pockets, so they work completely independently of one another. That lets the base respond to your body rather than moving as one piece.

Key benefits
- Room for two side sleepers: Each of you gets 75cm of soft, pillowtopped surface, which means knees and elbows are less likely to end up on your partner's side when you curl up.
- Quieter early starts: Independent pocket springs combined with 75cm each mean the partner who rises at dawn should disturb the one still asleep a little less than on a UK double.
- Length for taller sleepers: The UK king is 10cm longer than the UK double, which suits a partner over six foot whose feet would otherwise press into the pillowtop's edge.
- Space for propping pillows: During pregnancy, a support pillow takes up real width, and the extra 15cm over a UK double leaves room for it without squeezing your partner out.
- Room left for the dog: If your dog sleeps on the bed, the UK king gives it somewhere to settle at the foot without pinning either of you to the soft surface.
This size suits you if...
You share the bed with a partner and keep waking when they turn over or get up early, one of you is approaching or over six foot, and you both like a soft, cushioned bed rather than a firm one.
Consider another size if...
Your bedroom is smaller than our suggested minimum of 2.7m x 2.9m once the wardrobes are in. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Is the Sealy Enhance Platinum Pillow Top UK king big enough for two people?
For most couples, yes. The UK king gives 75cm each, which is 7.5cm more each than a UK double. If one of you sprawls or you share with a dog, the UK super king gives 90cm each, although you'll need at least 3m x 2.9m of floor space.
Will a UK king help with a partner who gets up much earlier than me?
It should help a little. The pocket springs work independently, and a UK king puts 75cm between you rather than the 67.5cm each of a UK double. Bear in mind a soft pillowtop still dips where someone sits on the edge to get up.
Is the UK king long enough for someone over six foot?
The UK king is 200cm long, 10cm longer than the UK double and UK small double. That extra length is often the main reason taller sleepers move up from a UK double, rather than the width.
What size room do I need for a UK king Sealy Enhance Platinum?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m comfortable. New build master bedrooms can feel smaller than their floor plan once wardrobes and bedside tables are in, so measure with the furniture in place.
Should I choose the UK king or the UK super king for a soft mattress?
The UK king suits most couples in an average bedroom. The UK super king gives 15cm more each, at 90cm, which helps if you're both restless on a soft surface, but it needs at least 3m x 2.9m, so measure first, then compare the retailers listed on this page.
