Assessed from the product page published by Mattress Online, captured September 2026, and from regular price comparison across our UK retail partners.
The main draw here is a soft feel at a genuinely modest price, from £239.00. Soft mattresses are harder to find than medium ones, so if you sleep on your side, or you simply prefer sinking in a little rather than lying on top of the bed, this is one of the more affordable ways to get that feel from a well-known brand. The cushion top adds a layer of surface comfort, which means less pressure on shoulders and hips. It is listed as an eco-friendly mattress, and one retailer lists a 5 year warranty. The spec detail available is thin, but the fundamentals are clear: soft, cushioned and inexpensive.
Key Features & what's inside

Who's it NOT for?
This is a soft mattress, so it will not suit anyone who needs a firm, supportive surface, including heavier sleepers and most front sleepers. If you share a bed with someone much heavier or lighter than you, a soft feel can also exaggerate roll-together. Firmer options would serve you better.
