The Finnish-made Fysicon Basic is an excellent standard mattress for hospital and care home use. The inside of the 12 cm thick Fysicon hygiene mattress is made of HR-35 material, in which one side of the mattress has a V profile. The covering is made of a polyurethane-coated, breathable hygiene fabric, which is liquid-proof. The zips on both sides of the mattress feature a double-sided insulation strip to stop liquid ingress via the zip into the mattress. The mattresses are ignitability class SL 1 (flame and cigarette test - IMO FTPC Part 9) and liquid-proof but still breathable. Normal care requires only wiping with diluted cleaning or disinfecting agent, and when necessary washing at 70-95 °C and careful tumble-drying at low temperature. In order to lengthen the service life of the mattress, turning it both lengthways and widthways is recommended.
