Layer Details
- Knitted Cover. A soft knitted cover that's breathable, which means heat can escape rather than build up around you. It helps keep you at an even temperature through the night.
- Memory Foam. This layer adds a soft, cushioning feel, gently moulding to your shape as you settle in. It takes the edge off the firm support underneath.
- Pocket Springs. Individually pocketed springs move independently from one another, so the mattress responds to your body's movements more effectively. In practice, that means support where you need it and less disturbance from a restless partner.

- Fits a typical bedroom: At 135 x 190cm, we suggest a room of at least 2.6m x 2.8m, which leaves space for a wardrobe in most main bedrooms and many second bedrooms.
- Less disturbance when sharing: The springs are individually pocketed, which means one person rolling over sends less movement across to the other.
- Firm support for two: A firm feel with a memory foam comfort layer suits couples who both sleep on their backs or fronts, although lightweight side sleepers may find it a little hard.
- Simple to dress: Standard double sheets fit, and a 200 x 200cm double duvet covers the bed comfortably, so bedding you already own should carry straight over.
- Sensible for a spare room: In a guest room it gives visiting couples a proper shared bed without the footprint of a UK king pushing furniture back against the walls.
This size suits you if...
You share with a partner in a bedroom of around 2.6m x 2.8m or a little more and you both like a firm surface, or you sleep alone and want extra room for a cat or dog who claims a corner.
Consider another size if...
You both sprawl, or one of you is tall, and your room clears 2.7m x 2.9m. We'd recommend the UK king instead, which gives you 7.5cm more each and is 10cm longer.

How much room does each person get on the Spring King Pocket Memory Ortho 1500 UK double?
Each of you gets 67.5cm of width on a 135 x 190cm surface. That suits most couples of average build. Because the springs are pocketed individually, you should feel a partner's movement less than you would on an open coil mattress, which helps when you're sleeping fairly close together.
Will a UK double Spring King Ortho 1500 fit in my bedroom with bedside tables?
We suggest a room of at least 2.6m x 2.8m for the UK double. A room of around 3m x 3m is more comfortable if you want bedside tables on both sides and space to walk round the bed. In a smaller room, measure before you order and leave space for opening the wardrobe doors.
What size is the Spring King Pocket Memory Ortho 1500 double in feet and inches?
The UK double measures 4ft 6in x 6ft 3in, which is 135 x 190cm. That is the standard UK double size, so it should drop into any UK double bed frame or divan base without gaps at the sides or foot.
How much extra space would the UK king Spring King Ortho 1500 give a couple?
The UK king gives 75cm each, so you would gain 7.5cm per person, and it is 10cm longer than the UK double. It needs more floor space, though: we suggest at least 2.7m x 2.9m for the UK king, compared with 2.6m x 2.8m for the UK double.
Is the UK small double Spring King Ortho 1500 big enough for two?
It is tight for regular sharing. The UK small double is 15cm narrower than the UK double, although both are the same length. It suits a solo sleeper or a very occasional guest better than a couple, and we suggest at least 2.4m x 2.8m for the UK small double.
