Disappointing Quality and Unpleasant Smell Unfortunately, Im very disappointed with this mattress. I bought it for my son, but I found it far too dense, heavy and uncomfortable. Im also not happy with its overall structure and quality. On top of that, it has a very strong, unpleasant smell that simply wont go away, even after several days. I expected much better quality, especially from a mattress designed for children. I wouldnt recommend it.. Rafaela. London, GB. Fri Oct 30 2026

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 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.
