The main draw is natural fibres at a budget price. Cashmere and wool sit near the sleep surface, which means better temperature regulation than an all-synthetic mattress, helpful if you tend to sleep warm. There's a quiet sustainability story too: the polyester layer uses 70% recycled single-use plastic and the foam layer is 100% reclaimed. The medium firmness suits most sleepers, although across owner reviews some found it softer than expected, so if you prefer a firmer edge to your support it may not be the one. Yes, 1000 springs is a modest count, but the Pocket+ design uses thicker wire and an extra row of springs to compensate. Priced £249 to £409 depending on size.
Key Features & what's inside
- Knit-Tex cover. A knitted cover with a tulip print, designed for breathability and airflow. In practice that means a fresher-feeling sleep surface, particularly useful if you run warm at night.
- Cashmere and Wool comfort layer. A blend of cashmere and wool fibres providing the main comfort layer. These natural fibres are highly breathable and help regulate temperature, which means fewer sweaty wake-ups than a purely synthetic top layer.
- Recycled polyester layer. A cushioning layer made from 70% recycled single-use plastic. It adds a little extra softness while giving the mattress a stronger environmental case.
- Eco foam layer. Made from 100% reclaimed foam, this layer moulds around your body to take pressure off your joints. It softens the transition between the fibre layers above and the springs below.
- Pocket+ springs. 1000 Pocket+ springs with thicker wire, special coil shapes and an extra row of springs, a count based on the kingsize. Each spring moves independently, which means the mattress adapts to your shape and you feel less of a partner's movement.

Who's it NOT for?
If you prefer a firm feel, look elsewhere: this is a medium, and some owners found it softer than expected. Heavier sleepers wanting deep, substantial support may also find the 23cm depth and 1000-spring count a little modest. And if edge-to-edge firmness matters to you, a higher-spec mattress is worth the extra.

How firm is the Aspire Pocket+ 1000 mattress?
It's a medium. That suits most sleeping positions, particularly side and combination sleepers. Worth knowing: some owner reviews mention it feels softer than expected, so if you like a firmer surface this may not be the right fit.
Does the Aspire Pocket+ 1000 come with a trial?
Mattress Online lists a 100-night comfort trial with this mattress. That's the retailer's own offer rather than a manufacturer promise, so if you buy elsewhere, check that retailer's returns terms before ordering.
What is the Aspire Pocket+ 1000 guarantee?
The mattressonline.co.uk listing states a 5 year guarantee. As with the trial, this is stated by the retailer, so confirm the guarantee terms with whichever shop you buy from.
Is the Aspire Pocket+ 1000 good for hot sleepers?
It should cope reasonably well. The wool and cashmere comfort layer is naturally breathable and helps with temperature regulation, and the Knit-Tex cover is designed for airflow. It's a better bet for warm sleepers than an all-foam mattress at a similar price.
What sizes does the Aspire Pocket+ 1000 come in?
Five UK sizes: Small Single, Single, Small Double, Double and King. Prices run from £249 to £409 depending on the size you choose. The 1000 spring count quoted is based on the kingsize, so smaller sizes will contain fewer springs.
