Why should you choose this mattress?
This one suits you if you want natural fillings and a supportive, medium to firm feel. The 1400 pocket springs move independently, which means your partner's tossing and turning is less likely to disturb you, and each part of your body gets support where it needs it. Wool and cotton fillings breathe and regulate temperature, so if you're a hot sleeper this is a sensible pick over foam. Yes, it's only listed in UK small double, but Mattress Online offers free delivery to most locations with a two-hour time slot, plus mattress recycling for an extra charge if you need your old one taken away.
Key features & layer details
Damask cover
A finely woven damask fabric that feels soft to the touch and doesn't retain heat. It's a durable weave, so it should hold up well over years of use.
Wool comfort fillings
Two layers of 100% British wool, a natural insulator with genuinely good temperature regulation. In practice that means warmth in winter and breathability in summer.
Cotton
Natural cotton fibres wick away moisture and help regulate body temperature. This keeps the sleeping surface feeling fresh rather than clammy.
Pocket springs
1400 individual springs, each encased in its own cloth pocket, adapt to your movement and distribute support across your body. This gives more personalised support than a traditional open coil, with less motion transfer between partners.

Best suited for?
Warm sleepers
Two layers of British wool and natural cotton breathe and regulate temperature, and there are no synthetic foams, so it should sleep cooler than memory foam.
Back sleepers
The medium firm feel and 1400 pocket springs give responsive support across the body, which suits those who like a steady, level surface.
Eco-conscious buyers
Natural wool and cotton fillings replace synthetic foams, and the mattress is handcrafted in the UK by a National Bed Federation approved brand.
Lighter sleepers
Each of the 1400 springs sits in its own cloth pocket and moves independently, which means less motion transfer if someone else shifts around.
If you need edge-to-edge firmness, owner reviews mention a slightly softer feel at the edges. It's also listed only in UK small double, so couples wanting a double or king will need to look elsewhere. And if you prefer a plush, sink-in surface, the medium to firm feel may be firmer than you'd like.
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
How firm is the Sleepeezee Strand 1400 mattress?
The retailer listing describes it as medium to firm, a supportive feel that suits most back and front sleepers. One owner review mentions the physical mattress label says 'medium', so if a precise firmness matters to you, it may be slightly softer than the description suggests. Lightweight side sleepers may still find it a little firm.
Does the Sleepeezee Strand 1400 come with a trial period?
Mattress Online lists a 100-night trial with this mattress, along with a 10-year guarantee. These are the retailer's own terms rather than a manufacturer offer, so check the conditions if you buy elsewhere.
Is the Sleepeezee Strand 1400 good for hot sleepers?
It's a strong choice. The fillings are British wool and cotton, both breathable natural fibres that regulate temperature and wick moisture, and the damask cover doesn't retain heat. There's no memory foam, which is the layer that most often traps warmth.
How deep is the Sleepeezee Strand 1400 mattress?
It's 25cm deep, which fits standard fitted sheets comfortably. Inside are 1400 pocket springs topped with two layers of wool and a layer of cotton.
Where is the Sleepeezee Strand 1400 made?
It's handcrafted in the UK, and Sleepeezee is a National Bed Federation approved brand. The mattress also conforms to BS7177: 2008 for fire resistance.
