Layer Details
- Comfort Layer. Soft white synthetic fibres create a cosy feel on the surface. These are lightweight, high-loft materials, which means they should hold their height and shape over time rather than flattening quickly.
- Support System. 2000 extra firm pocket springs contour around your body shape while pushing back against it, which means full body support and spinal alignment rather than a hammock effect. This is where the very firm, sturdy feel comes from.
- Edge Support. A wire rod runs along the perimeter of the pocket springs, giving you a durable edge that doesn't dip or sag. In practice, that means more usable sleep space right to the sides of the bed.

- 75cm each for two people sharing: That's 7.5cm more per person than the UK double, which means fewer accidental elbows and less waking each other on a surface with this much pushback.
- Springs that respond to you, not your partner: The 2000 pocket springs contour around each body individually, so one of you getting up at 5am is less likely to drag the other awake.
- Usable width right to the edge: A wire rod runs around the perimeter, so the sides shouldn't dip, and on a 150cm mattress that means the full width is genuinely sleepable.
- 200cm of length for taller sleepers: The UK king is 10cm longer than the UK double, a real difference if one of you is approaching six foot and tired of feet hanging over.
- A firm, stable surface for getting in and out: Extra firm support with a reinforced edge gives you something solid to push against, useful if you're recovering from injury or getting up frequently at night.
This size suits you if...
You share the bed every night and a double has started to feel cramped, especially with a mattress this firm, where you can't simply sink out of each other's way. Or one of you is tall and needs the 200cm length. It also suits couples on different schedules who want the early riser's movements to register less.
Consider another size if...
Your bedroom is smaller than the 2.7m x 2.9m we suggest for a UK king. The UK double needs less room, at least 2.6m x 2.8m by our guidance, and keeps the same extra firm feel.

Is the UK king Premium Gold 2000 big enough for two people?
Yes, comfortably for most couples. At 150 x 200cm it gives 75cm each for two people sharing, and the wire rod edge means the sides shouldn't dip, so that width is usable right to the perimeter. Because the surface is extra firm, having room to spread out matters: you can't burrow into it, so space does the work instead.
Will a UK king mattress fit in my bedroom?
We suggest a room of at least 2.7m x 2.9m for a UK king, which leaves space to walk round and open drawers. Measure with wardrobes and bedside tables in place, particularly in a new build master bedroom, which can feel smaller than the floor plan suggests once the furniture is in.
Should I choose the UK double or the UK king in this mattress?
If you share every night, the UK king is usually the better buy. It's 15cm wider and 10cm longer than the UK double, giving each of you 7.5cm more width. On an extra firm mattress that extra space reduces how much you notice a restless partner. Solo sleepers, or couples with a smaller room, may find the UK double sufficient.
Is the UK king long enough for a tall sleeper?
At 200cm (the UK king is 5ft x 6ft 6in), it's 10cm longer than the UK double, which is usually enough for anyone approaching six foot. Sizing up to the UK super king adds width, not length, since both sizes are 200cm long, so if length is your only concern the UK king already gives you the maximum.
Is the UK super king worth it over the UK king for this mattress?
Only if space allows. The UK super king is 30cm wider, giving 90cm each for two sharing against the UK king's 75cm, but we suggest a room of at least 3m x 2.9m for it. If a dog routinely joins you, or one of you sprawls, that extra 15cm each is tempting. Otherwise the UK king suits most couples.
