Why should you choose this mattress?
The soft Reflex foam top layer is designed to give you cushioned support, and the deep Ecofoam base below it is made from recycled and re-engineered foam, so it suits you if recycled materials matter. The cover is removable and washable, which makes it easier to keep fresh. The foam is described as hypoallergenic by Best Beds Direct, and it's made in the UK. It's no-turn, so you only rotate it head to toe. Because it comes rolled in a box, it's easy to get up stairs and into tight rooms.

If you need to know the firmness before you buy, this might not be the best choice, as Komfi doesn't publish a rating. It's a two-layer foam mattress with no springs, so you may want something with more bounce or a more structured feel. It's single-sided, so you can rotate it but not flip it.
Save on an earlier or ex-display model
