Pyrros is our most successful metal-free bed-mattress offering a 'weightless' experience. It provides optimum elasticity and isometric support for any body type and weight. Pyrros owes its superior quality to a unique combination of natural materials, layered on top of an ergonomic base. Dried seaweed contained inside soothes our breathing system, contributing to a restful sleep. The zipper opening makes it easy for you to flip the mattress inside and choose the desired level of elasticity for your exclusive bed. Moreover, it allows for easy maintenance and a longer lifespan. Pyrros' high-quality 100% organic cotton cover is padded with pure wool to protect mattresses from frictions. Double bed-mattresses are made of two single units, joined together by a clever click-system.
