Choosing a memory foam mattress
Start with how you sleep. The range is split into Essentials for those watching their budget, Coolmax fibres for a cooler night, and the 4G Aircool cooling mattress. If you run warm, the cooling options are the sensible place to look first, then check that the firmness suits your position.
Comparing firmness and size
The site lets you shop by firmness (soft, medium or firm) and by size from Small Single through to Super King. Side sleepers often prefer a softer feel for pressure relief, while back and front sleepers may find a medium or firm surface keeps the spine more level. Measure your bed frame before ordering, as sizes are listed separately.
Toppers, pillows and covers
If your current mattress is still sound, a memory foam topper can change the surface without replacing the base. The range also includes pillows and covers, which can be useful additions. Look at the topper depth and the cover type before deciding, since a thin topper adds less contouring than a full mattress.
Eco-friendly options
The Ecofoam range uses re-engineered foam made from foam offcuts. It is positioned as a more responsible option without a change in durability, and the company says it is used in structural areas such as mattress bases. Check the product description to confirm which models use it.
