Deeper cushioning for a softer, more enveloping night — ideal for couples and side sleepers upgrading their main bedroom. The extra depth goes into the comfort layer, so you settle further into the surface while the support beneath still holds you level. Because the foam absorbs movement rather than passing it across the bed, you're far less likely to be woken when your partner turns over. Delivered rolled and boxed. Once unwrapped, allow 48–72 hours in a well-heated, well-ventilated room for the mattress to expand to full size and for the initial foam odour to clear.

Our best-selling memory foam mattress, and it's easy to see why — great for guest rooms and first-time buyers, or anyone replacing a tired mattress on a sensible budget. At 20cm, memory foam does its best work: deep enough to cushion your shoulders and hips properly, firm enough underneath that you never feel like you're sinking. The foam moulds to your shape, easing pressure points and reducing motion transfer from a restless partner. Delivered rolled and boxed. Once unwrapped, allow 48–72 hours in a well-heated, well-ventilated room for the mattress to expand to full size and for the initial foam odour to clear.

Lovely bed! I have a small room and this helped having the storage underneath! Over time the mattress does slide forward as the sticky parts tend to wear but other than that it’s great!. Anonymous. Thu Jul 23 2026

Choosing a mattress shouldn't be complicated. With so many materials and specifications, understanding what truly matters can be difficult. At Swann Sleep, we believe better choices come from better understanding. Every material has a purpose, and every layer contributes to your sleep. During sleep, your body naturally creates more pressure around areas such as your shoulders, hips and lower back. This is why comfort begins with a material that can respond to your body's shape. The mattress uses SensaContour 40kg/m³ Memory Foam, a high-density memory foam layer designed to gently contour around your body and help distribute weight more evenly for a more comfortable sleeping surface. But comfort alone is not enough. A mattress also needs to support you as you move. As sleeping positions change throughout the night, materials need to respond quickly while maintaining balance. Beneath the memory foam, 30kg/m³ Reflex Foam provides a responsive transition layer, helping the mattress recover naturally and maintain consistent support. The foundation beneath these layers plays an equally important role. Without a durable support core, the comfort materials above cannot perform at their best over time. That's why the Balance Memory Foam Mattress uses EcoFoam, a high-density support layer created by repurposing premium polyurethane foam. It provides the stability needed for long-lasting performance while supporting a more considered approach to material use. Comfort also begins before you reach the foam layers. The mattress is finished with a soft bamboo non-quilted cover and manufactured in the UK using carefully selected materials.
