Layer Details
- Cover. A soft knitted cover that is breathable, which means heat can escape rather than build up under you. It helps keep you at a more even temperature through the night.
- Memory Foam. This layer moulds to your body, which means pressure points such as hips and shoulders get some relief while you still feel supported. It is where the orthopaedic comfort of the mattress comes from.
- Open Coil Springs. Interlaced coils of high-tensile steel joined together in a lattice. Because the coils are connected, the surface responds as one unit, giving broad, even body support with a traditionally firm feel.

- A shared bed that suits ordinary rooms: At 4ft 6in x 6ft 3in, the UK double leaves space for a wardrobe and drawers in rooms where a UK king would crowd everything else out.
- Firm support for both sleepers: The connected open coil unit holds the whole surface level, which means neither partner rolls into a dip even when you sleep slightly unevenly apart.
- Pressure relief on a sharing budget: Memory foam above the springs eases hips and shoulders for two people, a useful combination when you are furnishing several rooms at once and cannot overspend on one.
- Easy to dress: A standard 200 x 200cm double duvet and double sheets fit this mattress, so you can pick up bedding almost anywhere without hunting for unusual sizes.
- A dependable guest room option: Visiting couples get 67.5cm each on a firm, supportive surface, which is enough for a few nights without giving a spare room over entirely to the bed.
This size suits you if...
You share a bed in a bedroom of typical UK proportions and want firm support without the bed taking over the room, or you are kitting out a guest room for visiting couples on a careful budget.
Consider another size if...
You and your partner are restless sleepers who want more personal space than 67.5cm each. We'd recommend the UK king instead, which gives 75cm each; we suggest at least 2.7m x 2.9m for the UK king.

Will we feel each other move on the Spring King Memory Ortho UK double?
Probably a little. Open coil springs are linked, so movement travels across the surface more than it would with pocket springs. On a UK double you each have 67.5cm, which keeps you fairly close together. Light sleepers sharing may notice a partner turning over, although the memory foam layer softens some of that movement.
Can I fit bedside tables either side of a Spring King Memory Ortho UK double?
In most rooms, yes. We suggest at least 2.6m x 2.8m for a UK double, but around 3m x 3m is the comfortable norm if you want a table on each side and room to walk round the bed. Measure your wall space before ordering rather than relying on the room's listed size.
Should couples size up from the Spring King Memory Ortho UK double to the UK king?
If your room allows it and you want more elbow room, it is a reasonable step. The UK king is 15cm wider and 10cm longer than the UK double, giving 75cm each instead of 67.5cm. We suggest at least 2.7m x 2.9m for the UK king, so check your floor space first.
Is the Spring King Memory Ortho double good for one person with a pet?
It suits a solo sleeper with a dog or cat well. At 135cm wide, there is enough room for an animal to claim a corner without pushing you to the edge. The UK small double is 15cm narrower, so if your pet likes to stretch out, the UK double is the more comfortable choice.
Is the Spring King Memory Ortho UK double long enough for tall couples?
At 190cm long, the UK double is the same length as the UK single and UK small double. Taller sleepers whose feet already reach the end of a standard bed may prefer the UK king, which is 10cm longer. Most couples of average height will find the UK double long enough.
