Layer Details
Oeko-Tex fabric quilted surface
A quilted sleep surface made with Oeko-Tex certified fabric, which means the textile has been independently tested for harmful substances. It gives the top a slightly cushioned, padded feel from the first touch.
Memory foam comfort layer
Memory foam sits directly beneath the quilting, moulding to your shape and easing pressure at the shoulders and hips. It also gives the mattress its slower, more cradling surface feel.
Pocket+ 1000 spring system
A unit of 1,000 individually pocketed springs, each moving independently, which means less motion transfer to a partner and support that follows your body rather than pushing back as one block.
Eco foam support layer
An eco foam base layer that stabilises the springs and adds durability to the structure. It's the foundation the rest of the mattress works from.

Key benefits
- Space for two to sleep properly: At 75cm each for two people sharing, you can shift position or prop up on pillows without crowding the person next to you.
- Pocket springs matter more at this width: The 1,000 individually pocketed springs move independently, which means an early riser can slip out at 5am with far less disturbance across a 150cm surface.
- Length for taller sleepers: The UK king is 200cm long, 10cm more than the UK double, so anyone approaching 6ft gets their feet on the mattress rather than off the end.
- Room to accommodate a restless night: Memory foam eases pressure at shoulders and hips, and the wider surface gives you space to change position during pregnancy or recovery without waking a partner.
- The biggest size Aspire makes in this model: The Pocket+ 1000 range stops at the UK king, so this is the most sharing space you can get in this mattress.
This size suits you if...
You share the bed every night and a double has started to feel cramped, one of you gets up hours before the other and you want their movement absorbed rather than transmitted, or one of you is approaching 6ft and needs the 200cm length. It also suits couples expecting a baby, or anyone whose dog has quietly claimed a third of the mattress.
Consider another size if...
Your bedroom is under our suggested minimum of 2.7m x 2.9m for a UK king. In that case we'd recommend the UK double instead, which needs at least 2.6m x 2.8m and is 15cm narrower.

FAQ's
Is the Aspire Pocket+ 1000 available in a super king?
No. The UK king, at 150 x 200cm, is the largest size Aspire makes in the Pocket+ 1000 Memory Box Top. If you want the extra 30cm of width a UK super king offers, you'd need to look at a different mattress rather than a different size of this one.
Is the Aspire Pocket+ 1000 in a UK king good for couples?
It suits most sharing couples well. You get 75cm each, and the 1,000 pocket springs move independently, so one person turning over or getting up early transfers less movement to the other side. Heavier front sleepers who prefer a firm surface may find the medium feel a little too forgiving, though.
What room size do I need for the Aspire Pocket+ 1000 UK king?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable once wardrobes and bedside tables are in. New build master bedrooms can be tighter than they look on a floor plan, so measure with furniture in mind before committing to a UK king.
Is the king size of this mattress big enough for someone over 6ft?
The UK king is 200cm long, which comfortably accommodates most sleepers over 6ft. That extra length is often the real reason to size up: the UK double is 10cm shorter, so a taller sleeper gains legroom as well as width by choosing the UK king.
Where can I buy the Aspire Pocket+ 1000 in a UK king?
Availability shifts, so the most reliable answer is the live comparison table on this page, where prices are updated as retailers change them. It's worth checking back before you buy, because stock and pricing for individual sizes can move independently of the rest of the range.
