Why should you choose this mattress?
If you want natural materials without a natural-materials price tag, this is where this mattress makes its case. The wool and viscose cover is naturally fire retardant with zero chemical treatments, and the 750 pocket springs are ultrasonically welded rather than glued, so the whole construction is cleaner than most at a mid-range starting price. The medium firmness suits most sleepers, although those who prefer a very firm surface should look elsewhere. Buying through Mattress Online, you get a 100-night trial, though it requires purchasing a mattress protector from them and allows an exchange after 30 nights. A 5-year guarantee is listed by the retailer, shorter than some brands offer, but good cover for the price.
Key features & layer details
Cover
A FabriSafe cover made from wool yarn and viscose fabric, which is naturally fire retardant with zero chemical treatments. That means it meets safety standards without sprayed-on chemicals near your skin.
Comfort Layer
Traceable British wool paired with recycled polyester fibres for cushioning. Wool helps regulate temperature, so it works across warmer and cooler nights.
Support System
750 Cortec Quad steel pocket springs, each in its own fabric pocket, welded together ultrasonically and completely glue-free. Individual pockets mean the springs respond to your shape rather than moving as one block.

Best suited for?
Eco-conscious buyers
Traceable British wool, recycled polyester fibres and a glue-free, ultrasonically welded spring unit mean the materials lean natural and the construction avoids adhesives.
Allergy sufferers
The FabriSafe wool and viscose cover is naturally fire retardant with zero chemical treatments, so there are no sprayed-on chemicals sitting near your skin.
Warm sleepers
Wool in the comfort layer helps regulate temperature, which means the mattress should work across both warmer and cooler nights without feeling stuffy.
Couples
Each of the 750 pocket springs sits in its own fabric pocket, so they respond to each person's shape rather than moving as one block.
Combination sleepers
Medium tension aims at the middle ground, which suits changing between positions overnight without feeling too hard or too sunk in.
This isn't the mattress for you if you need a very firm or very soft feel: the medium tension aims at the middle ground. There's no memory foam layer either, so if you like that slow, cradling sink, a hybrid or foam mattress would suit you better. Heavier sleepers may want a higher spring count.
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.
