The offer applies to a polyurethane foam mattress Dimensions: 200x90x15cm! This mattress has 7 cut-out comfort zones and is made of medium-firm (H3) foam of excellent quality, marked T2540. We source the foam from a renowned European manufacturer, making it among the best on the market, and its weight (25 kg/m3) guarantees comfortable use for many years, without the risk of sagging or deformation. It provides adequate cushioning, has an airy structure, is flexible, and resilient. Thanks to the cut-out zones, the mattress adapts perfectly to the shape of our body, and the resulting air channels effectively dissipate excess heat during sleep. Excessive temperature, lack of ventilation, and limited heat exchange are the most common causes of sleep problems at night. Completing the look is an anti-allergic cover quilted with air-conditioning fabric. All this guarantees excellent sleep quality, without worrying about back pain or sleep deprivation. mattress constructionDense and durable polyurethane foamDense microfiber cover quilted with air-conditioning fabricZipper for easy removal and installation of the coverAir circulation directionSeven hardness zones:a.

Foot support zone We spend 1/3 of our lives in bed, so let's make sure it's a time of comfort, relaxation, and pleasure!We always provide two values that characterize polyurethane foam. The first indicates the mass in m3 (the higher the value, the denser the foam, and the mattress will retain its shape longer and allow for comfortable sleep). Only the second value indicates the firmness (the higher the value, the firmer the mattress). Remember that we pay for 1 kg of foam in m3, so a T30 mattress is 20% more expensive in production than the popular T25 (if this is true and T25 isn't just an average of T2030 foam—which is absolutely unsuitable for a mattress and actually has 25 kg/m3). Most sellers don't specify the specific density of the foam they use (how many m3 there are in 1 kg)!
