Layer Details
Comfort Layer
Soft white synthetic fibres sit on top, which means a cosy initial feel without the sink of memory foam. They're designed to be durable and resilient, holding their shape over time.
Support System
Traditional open coil springs are interlaced in a lattice design, joined together so the whole surface moves as one. That spreads your weight evenly, easing built-up pressure and helping spinal alignment, though you'll feel more partner movement than with pocket springs.

Key benefits
- The standard couples' footprint: At 135 x 190cm, the UK double is the long established size for two, giving 67.5cm each for two people sharing.
- Fits typical UK bedrooms: We suggest a room of at least 2.6m x 2.8m, which leaves space for a wardrobe and drawers in most second bedrooms and first flats.
- Medium firm support across the full width: The open coil lattice moves as one surface, which means even, familiar support edge to edge rather than a contoured feel.
- Easy to dress cheaply: Double sheets and 200 x 200cm duvets are sold everywhere at every price, useful if you're kitting out a whole home at once.
- A practical guest room buy: A UK double comfortably sleeps visiting couples, and at this price the short 1-year guarantee matters less for occasional use.
This size suits you if...
You're a couple in a typical UK bedroom where a bigger bed would dominate the floor space, you're setting up a first flat or second bedroom on a careful budget, or you want a guest room bed that can take visiting couples without a big outlay. It also suits a solo sleeper who likes room to spread out, or shares with a pet that claims a corner.
Consider another size if...
You share the bed nightly and one of you is a light sleeper, since open coils carry movement across the surface and 67.5cm each is snug. If your room allows at least 2.7m x 2.9m, we'd recommend the UK king instead.

FAQ's
Is the Classic Gold in a UK double big enough for a couple?
It works, with a caveat. The UK double gives 67.5cm each for two people sharing, which most couples find adequate rather than roomy. Because the Classic Gold uses open coil springs joined in a lattice, you'll feel a partner turning over more than you would on pocket springs. Fine for sound sleepers, less so for light ones.
What size room do I need for the Classic Gold UK double?
We suggest a room of at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows the bed, a wardrobe and a chest of drawers, and in most rooms leaves enough clearance for bedside tables on both sides. This is our guidance rather than the manufacturer's.
Should I get the Classic Gold in a UK double or a UK king?
The UK double is 15cm narrower and 10cm shorter than the UK king, and open coils transfer movement, so couples with the space may prefer the extra width of a UK king. We suggest at least 2.7m x 2.9m for the UK king. If your room is smaller than that, the UK double is the sensible choice.
Will a UK double mattress fit up narrow stairs?
Usually, yes. At 135 x 190cm it's a manageable size on the turning stairs of older terraces and tight new build landings, though the Classic Gold's sprung construction means it arrives flat rather than rolled, so measure any awkward corners first. Room delivery is available if you'd rather someone else carried it up.
Is the Classic Gold double a good guest room mattress?
It's one of the better uses for it. A UK double sleeps visiting couples comfortably, the medium firm open coil feel suits most people for short stays, and the low price makes sense for a bed used a few weeks a year. The motion transfer that bothers everyday couples rarely matters to guests.
