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
- Real room for one: The UK small double is 30cm wider than the UK single, so a solo adult can stretch, roll and change position without meeting the edge.
- Fits compact bedrooms: At 15cm narrower than the UK double, it slots into box rooms, studios and loft conversions where a 4ft 6in frame would block walking space.
- Motion transfer matters less solo: Open coils move as one surface, which a couple would feel nightly, but a lone sleeper in this size rarely notices.
- Sensible for guest rooms: A budget build in a size that sleeps one comfortably and two occasionally makes a low-cost, low-risk spare bed.
- Standard 4ft sizing: The small double is a standard UK size, so frames and 4ft fitted sheets are easy to find on the high street.
This size suits you if...
You're a solo sleeper who has outgrown a single but your room can't take a full double, you're furnishing a guest room or holiday let where couples stay occasionally rather than nightly, or you're kitting out a teenager's bedroom on a budget and the extra 30cm over a UK single is the point.
Consider another size if...
You share the bed every night, because open coils transfer movement and 120cm is snug for two. We'd recommend the UK double instead, allowing at least 2.6m x 2.8m of floor space.

FAQ's
Is the Classic Gold small double big enough for a couple?
For occasional nights, yes. At 120 x 190cm two adults will fit, and for a guest room that's usually enough. As an every-night bed for two it falls short: the width is snug, and the open coil springs move as one surface, so you'll feel a partner turning over. Nightly sharers should look at the UK double.
What room size do I need for a small double Classic Gold?
We suggest at least 2.4m x 2.8m, which leaves enough space to walk around the bed and open drawers. That's our guidance rather than the manufacturer's. If your room comfortably exceeds 2.6m x 2.8m, the UK double becomes an option, so measure before you decide the small double is your ceiling.
Is the small double a good upgrade from a single for a teenager?
It's a sensible one. The UK small double is 30cm wider than the UK single and exactly the same length, so a growing teenager gains real width without the bed eating more floor down its length. The Classic Gold's budget price also suits a bed that may be replaced within a few years anyway.
How does the small double compare with the UK king in this mattress?
The UK small double is 30cm narrower and 10cm shorter than the UK king, and the king needs a room of at least 2.7m x 2.9m against 2.4m x 2.8m for the small double. If you have the space and share nightly, the king is the more comfortable long-term choice.
