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.

Key benefits
- A shared bed for average rooms: At 135 x 190cm it fits comfortably in bedrooms where a UK king would crowd the walkways, so allow at least 2.6m x 2.8m.
- Firm enough that movement stays put: Extra firm pocket springs resist that dip towards the middle, which matters more in a UK double where 67.5cm each leaves little spare width.
- Usable width right to the edge: The wire rod edge means the sides shouldn't sag, so each sleeper can use their full share of a 135cm width without teetering.
- Room left for the rest of the furniture: In a second bedroom or first flat, this footprint usually still leaves space for a wardrobe and drawers, which a bigger size often doesn't.
- Easier to get upstairs: At 4ft 6in x 6ft 3in, a UK double turns the awkward stairs of older terraces more readily than the longer UK king.
This size suits you if...
You share the bed in a room of ordinary UK proportions and want a firm, stable surface that keeps you both on your own side, or you sleep alone and like space to spread out. It also suits a guest room that hosts visiting couples, since extra firm support copes with a range of body weights, and the size fits alongside the furniture a spare room already holds.
Consider another size if...
You and your partner both want more personal space and your room can take it. The UK king is 15cm wider and 10cm longer, giving 75cm each rather than 67.5cm; allow at least 2.7m x 2.9m for it.

FAQ's
Is a UK double Premium Gold 2000 wide enough for two adults?
You get 67.5cm of width each, which is workable rather than generous. The extra firm feel helps here: neither sleeper sinks a hollow that pulls the other across, and the wire rod edge keeps the sides usable, so the full 135cm counts. If either of you sleeps restlessly or spreads out, the UK king gives 75cm each.
Will a UK double fit my bedroom with bedside tables both sides?
Usually, yes. The mattress is 135cm wide, and we suggest a room of at least 2.6m x 2.8m, which typically leaves enough on either side for a slim table and space to walk past. If you can only fit a table on one side, the UK small double, 15cm narrower, may suit the room better.
Should a couple choose the double or the UK king in an extra firm mattress?
On an extra firm surface you don't sink and sprawl, so width matters slightly more than on softer builds. The UK double works if your room is modest, but the UK king gives you 7.5cm more each and 10cm extra length; allow at least 2.7m x 2.9m for it. Measure the room before deciding.
Is the double Premium Gold 2000 easy to get up narrow stairs?
At 4ft 6in x 6ft 3in it's one of the easier shared sizes to manoeuvre, and being a sprung mattress it shouldn't be bent or folded, so the shorter footprint helps on the turning stairs of older terraces and tight new build landings. Measure your tightest corner against 135 x 190cm before ordering.
Is a UK double a good guest room size for this mattress?
Yes, with one caveat. It sleeps visiting couples properly while leaving room for a wardrobe and drawers in a spare room, and the hypoallergenic build suits guests with allergies. The caveat is firmness: this is genuinely extra firm, and lightweight side sleepers among your guests may find it presses on shoulders and hips.
