Why should you choose this mattress?
Natural fillings at an affordable starting price are genuinely uncommon. The cashmere top layer is breathable and wicks moisture, which means less of that clammy feeling on warmer nights, while the wool beneath insulates and regulates temperature year round. The 1,000 pocket springs move independently, so you get support that follows your shape rather than a flat, uniform push back. A 5 year guarantee and a 100-night trial through Mattress Online give you a decent safety net. For back and combination sleepers wanting natural comfort on a budget, it makes a strong case.
Key features & layer details
Cashmere
A luxuriously soft natural filling that sits at the top of the mattress. It's highly breathable with good moisture-wicking properties, which means the sleep surface should stay drier and cooler through the night.
Wool
A natural insulator with strong temperature-regulating properties. In practice, it helps keep you warm in winter and stops heat building up in summer.
Recycled polyester fibres
A layer of recycled polyester fibres that boosts the softness and comfort of the mattress. It adds a little extra cushioning between the natural fillings and the springs.
Pocket Springs
1,000 individual pocket springs, a count based on the kingsize, each responding separately to pressure. That means individualised support for your sleep posture, which can help relieve aches and pains.

Best suited for?
Back sleepers
The medium firm feel and 1,000 independent pocket springs give support that follows your shape, which suits lying on your back with the spine well held.
Combination sleepers
Individually moving pocket springs under a soft cashmere top layer respond as you change position, so shifting between positions through the night feels easy.
Budget buyers
The copy places it at the affordable end for a natural-filled pocket sprung mattress, so cashmere and wool fillings are within reach without a premium feel.
Eco-conscious buyers
Natural cashmere and wool fillings, UK handcrafting and SMETA accreditation for ethical production give a clear story for anyone who cares how their bed is made.
Couples
Each of the 1,000 pocket springs responds separately to pressure, and six sizes up to super king leave plenty of room to choose a bed for two.
If you want a genuinely firm mattress, look elsewhere: the product page lists this as medium, and while one owner found it firmer than expected, it isn't built for those who need a solid, unyielding surface. Hot sleepers who run very warm may also want to note some owners describe it as warm.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
Is the Aspire Natural Cashmere 1000 mattress firm or medium?
The product page lists it as medium, though at least one reviewer found it firmer than expected. It should suit most back and combination sleepers, although lightweight side sleepers may want something softer, and if you prefer a firm mattress, you may find it too forgiving.
Does the Aspire Natural Cashmere 1000 come with a trial?
Mattress Online lists a 100-night trial with this mattress. That's the retailer's own offer rather than a manufacturer promise, so check the terms with whichever retailer you buy from.
How many springs does the Aspire Natural Cashmere 1000 have?
It contains 1,000 pocket springs, though the listing notes this count is based on the kingsize, so smaller sizes will have fewer. Each spring moves independently, giving support that adapts to your body shape.
How deep is the Aspire Natural Cashmere 1000 Pocket Mattress?
It's 28cm deep, a reasonably generous depth that should work with standard fitted sheets. The depth comes from layers of cashmere, wool and recycled polyester fibres over the pocket spring unit.
What guarantee does the Aspire Natural Cashmere 1000 have?
The Mattress Online listing states a 5 year guarantee. The mattress is handcrafted in the UK and conforms to BS7177: 2008 fire resistance standards for domestic use.
