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.

- 75cm each for two people sharing: Each of you gets 75cm of width, so a partner who leaves for work hours before you can slip out without a tug of war over territory.
- Extra width softens the open coil trade-off: Open coils transfer movement across the whole mattress, but the UK king's added width puts more distance between you, which takes the edge off a restless partner.
- 200cm of length for taller sleepers: At 5ft x 6ft 6in, this size is 10cm longer than the UK double, a real relief if one of you is nudging six foot.
- Room to shift position at night: During pregnancy or after an injury, when you're propping pillows and changing position often, the extra space means less disturbance for whoever is sharing.
- The top size at a budget price: King is where budget ranges often thin out, so getting this much space with a simple, honest construction is the Classic Gold's strongest argument.
This size suits you if...
You share the bed every night and have outgrown a double, especially if one of you is tall enough to appreciate the extra 10cm of length, or you're on different schedules and want enough width that one person getting up doesn't wake the other. It also suits a guest room where couples stay regularly and you want them comfortable without spending much.
Consider another size if...
Your bedroom can't manage the 2.7m x 2.9m we suggest for a UK king, or you mostly sleep alone. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m and still sleeps two.

Is the Classic Gold in a UK king good for couples?
Yes, with one caveat. The 150cm width gives you 75cm each, plenty for two adults. The open coil springs are joined together, though, so you will feel a partner turning over more than you would on pocket springs. The width of a UK king helps here: more distance between you means less of that movement reaching your side.
Will a UK king Classic Gold fit in a new build master bedroom?
Often, but measure first. New build masters can feel smaller than they look once fitted wardrobes go in. We suggest at least 2.7m x 2.9m for a UK king so you can walk round both sides. If you're short of that, the UK double is 15cm narrower and needs at least 2.6m x 2.8m.
Is the UK king long enough for someone over six foot?
At 200cm long, it leaves reasonable clearance for anyone around the six foot mark, and it's 10cm longer than the UK double. If length is the reason you're upgrading, the UK king is the right move on this mattress, since it's the largest size the Classic Gold is made in.
Does the Classic Gold come in a super king?
No. The UK king, at 150 x 200cm, is the biggest size available for this mattress. If you had your heart set on super king space, you'd need to look at a different model, but for most couples the king's 75cm each is a comfortable amount of room.
