Layer Details
Damask cover
A finely woven damask fabric that's soft to the touch and doesn't retain heat, which means the sleep surface stays cooler than many synthetic covers. It's built for long-lasting performance too.
Soft White Fibres
Soft synthetic fillings that create a cosy initial feel when you lie down. They're durable and resilient, so they should hold their shape rather than flattening quickly.
Silk and polyester layer
A blended silk and polyester layer that's highly breathable. This increases airflow through the mattress, reducing heat and moisture buildup, which matters if you're a warm sleeper.
Dual density polyester fibre pad
Soft and plush on the side facing you for comfort. The denser reverse side supports the spring system beneath, helping the layers work together.
Pocket Springs
1500 pocket springs, each encased in its own cloth pocket. Because they move individually, they adapt to your body and reduce the ripple effect when a partner moves.

Key benefits
- Room to sprawl on your own: The UK small double is 30cm wider than the UK single, which means a solo sleeper can shift position freely without an arm hanging off the edge.
- Fits where a double won't: At 15cm narrower than the UK double, this size can be the difference between a wardrobe door that opens and one that doesn't.
- Same length as a single: Both the UK small double and the UK single run to 190cm, so upgrading in width won't cost you anything at the foot of the room.
- Traditional build in a compact size: You get the full 1500 pocket springs and UK handcrafting in this size, so a smaller room doesn't mean a lesser mattress.
- Cool for a snug space: Smaller bedrooms can run warm, and the breathable silk and polyester layer helps air move through the mattress rather than trapping heat around you.
- Easy bedding: 4ft is a standard UK size, so small double fitted sheets are simple to find and a standard double duvet drapes generously.
This size suits you if...
You sleep alone and have outgrown a UK single but your room can't take a full double, you're furnishing a box room, loft conversion or studio where every centimetre of width matters, or you're kitting out a guest room where couples stay occasionally rather than nightly. The medium firm feel and individually moving pocket springs suit a solo adult who wants gentle, responsive comfort without a foam feel.
Consider another size if...
You and a partner will share the bed every night, since two adults on 120cm is a squeeze long term. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m for it.

FAQ's
Is the Relyon Anna 1500 small double big enough for a couple?
For occasional nights, yes, and the 1500 pocket springs move individually, so you'll feel less of each other's shifting than on a basic sprung mattress. For every night, it's a little tight for two adults. Sizing up to the UK double gives 67.5cm of width each, which makes a real difference over months of sharing.
What room size do I need for a small double mattress?
We suggest at least 2.4m x 2.8m for the UK small double, which leaves enough clearance to walk round the bed and open doors and drawers. That's our own guidance rather than Relyon's. If your room comfortably exceeds 2.6m x 2.8m and you share the bed, the UK double becomes the more sensible buy.
How much wider is the small double Anna 1500 than a single?
The UK small double is 30cm wider than the UK single, and the two are the same length at 190cm. In practice that extra width means a solo sleeper can starfish, roll over or read in bed without feeling hemmed in, while the room loses only 30cm of floor space compared with a single.
Will a small double fit in a loft conversion or box room?
Often, yes, and that's this size's main appeal. At 120cm wide it's 15cm narrower than a standard double, which can be exactly the margin that keeps standing room beside the bed under a sloping ceiling, or lets a box room door swing clear. Measure your usable floor against our suggested 2.4m x 2.8m minimum first.
Is the small double Anna 1500 a good guest room mattress?
It's a strong fit for a guest room that hosts a mix of solo visitors and the occasional couple. One person gets generous space, two can share for a weekend, and the breathable silk and polyester layer keeps the surface fresh between stays. If guests are usually couples staying longer, the UK double would suit better.
