Iraklis is a firm mattress with medium elasticity, designed especially for children and persons of light weight. The mattress has two sides of different elasticity, making it possible to turn the mattress. This is particularly convenient when children grow older and require a more elastic surface. Iraklis is completely metal-free. The quilted mattress cover is made from cotton and wool and is Oeko-Tex certified (standard 100). It can be removed and cleaned.
