Layer Details
- Knitted cover. A soft knitted top layer that adds cosiness while allowing airflow through the surface. That breathability helps you sleep a little cooler.
- Eco Poly Comfort fibres. Plush recycled polyester fibres that give the surface its soft, cushioned feel. They also help extend the lifespan of the mattress.
- Mem-Tech foam. Memory foam that adapts around your body, which means pressure is lifted from areas like hips and shoulders as you settle in. You'll feel a gentle, enveloping sort of comfort.
- Eco Support Foam. A layer of recycled foam that adds a secure, durable feel beneath the softer comfort layers. It reinforces the support of the mattress while keeping a cushioned quality.
- Eco titan insulator layers. These sit between the foams and the springs, dispersing pressure from the spring unit. The result is more even weight distribution across the mattress.
- 1000 Pocket+ springs. One thousand springs, each encased in its own cloth pocket, respond individually to your movements for personalised full body support. They're built with extra resilience to bounce back to shape even after being rolled.

- Genuine stretching room for one: Sleeping alone on 120cm of width means you can roll, sprawl and change position freely, with the 1000 pocket springs responding only where you actually lie.
- Fits rooms a double crowds: At 15cm narrower than a UK double, this size can leave walking space beside the bed in a box room or studio where a double would not.
- Modest room requirement: We suggest at least 2.4m x 2.8m for a UK small double, which brings plenty of second bedrooms and loft conversions into play.
- Works for occasional guests: Two people can share it for the odd night, and the individually pocketed springs limit how much one sleeper's movement disturbs the other.
- Easy to dress: 4ft is a standard UK size, so small double fitted sheets are simple to find and a standard double duvet drapes generously over it.
- Lighter on the budget: This mattress sits at the affordable end for a pocket-sprung hybrid, so kitting out a guest room or teenager's room stays manageable.
This size suits you if...
You sleep alone and have outgrown a single but your room can't spare the floor space a double takes, you're furnishing a guest room where couples stay occasionally rather than nightly, or you're fitting out a compact second bedroom in a rental or holiday let and need a bed that still leaves space to move around it.
Consider another size if...
You share the bed most nights, because 120cm is a squeeze for two regular sleepers. We'd recommend the UK double instead: it's 15cm wider, the same length, and needs a room of at least 2.6m x 2.8m.

Is a small double Aspire Invigorate 1000 big enough for a couple?
For occasional nights, yes. The pocket springs respond to each sleeper individually, which softens the effect of sharing, but at 120cm wide it's a snug fit for two adults every night. Couples using it as their main bed would be more comfortable on the UK double, which gives you 15cm more width.
What room size do I need for the Aspire Invigorate 1000 in a small double?
We suggest a room of at least 2.4m x 2.8m. The mattress itself is 120 x 190cm, and that guidance leaves enough clearance to open the door, walk alongside the bed and get in and out without shuffling sideways. It's our own recommendation, so treat it as a comfortable minimum rather than a hard rule.
How much bigger is a small double than a single mattress?
The UK small double is 30cm wider than the UK single, and both are the same 190cm length. On this mattress that extra width means a solo adult can spread out properly across the pocket springs rather than sleeping in one fixed position, which is why it suits teenagers who have outgrown a single.
What bedding fits the Aspire Invigorate 1000 small double?
You'll need small double (4ft) fitted sheets, and because 4ft is a standard UK size they're easy to find on the high street and online. A standard double duvet works well on top and hangs a little further down each side than it would on a UK double, which many people rather like.
Should I size up to the double or king instead?
If your room allows, possibly. The UK double is 15cm wider and the same length, needing at least 2.6m x 2.8m. The UK king is 30cm wider and 10cm longer, needing at least 2.7m x 2.9m. Stick with the small double if floor space, a door swing or a sloping ceiling is the deciding factor.
