The offer applies to an extremely functional foam mattress Polyurethane foam with dimensions of 200x100x17cm!This model is characterized by two hardness levels: H3 - medium-firm and H4 - hard. One side is made of very dense, hard Hyperschaum polyurethane foam with a reinforced cell structure (8cm N3550 - 35kg/m3), while the other is a medium-firm layer of highly elastic Kaltschaum foam (8cm HR4030 - 40kg/m3) with an even higher density! The use of these top-quality components guarantees comfortable use for many years, without fear of the mattress sagging or deforming. It is perfect for both home and hotel or guesthouse use.Highly elastic (HR) H3 foam has a smooth texture and irregular structure, characterized by high point elasticity and dynamic behavior during load changes. This provides excellent body support, guaranteeing an ideal sleeping position and maximum comfort. It is very resistant to stretching or intense crushing and quickly regains its shape. Thanks to its open-cell structure, it ensures good ventilation and air permeability.Too high temperature, lack of ventilation and limited heat exchange are the most common causes of sleep problems at night.The whole is complemented by a finely quilted, membrane cover made of microfibre mattress fabric, with a four-way zipper for easy removal and dressing.We spend 1/3 of our lives in bed, so let's make sure it's a time of comfort, relaxation and pleasure! mattress constructionPage H4 - Hyperschaum N3550 foamPage H3 - Kaltschaum HR4030 foamCover made of dense microfibre quilted with air-conditioning non-woven fabricZipper for easy removal and installation of the cover Main features of the presented mattress:*Polish product of the highest quality (manufacturer - without intermediaries)*dimensions 100x200x17cm (tolerance 2%) - interior 16cm plus cover*polyurethane foam layerN3550 (up to 35kg/m3) H4 - side ideal for people with a higher weight (90-130kg), having back problems or simply for those who like to sleep on a harder surface*highly elastic foam layer HR4030 (up to 40 kg/m3) H3 - extremely comfortable and elastic side, for people with an average weight (approx. 50-85 kg) or preferring an intermediate Mattress hardness.*removable, anti-allergic, three-layer cover made of microfiber quilted with breathable wadding with a total density of up to 200 gr/m2, washable at 60*C and with zippers on at least two sides.*two-sided (can be turned)*multi-season (winter/summer) We use certified and attested raw materials to produce our mattress.
