The Mattresses which FitatSea supplies are only according to the genuine IMO/MED Wheelmark certificates. This is the highest fire-retardancy and demanded by many countries and offshore clients and regulations. We have three different types of mattresses as you can below. The most sold type is the Bonnell Mattress. This is a combination of Spring and Foam and takes away the necessity of having an extra top-mattress. All mattresses can be delivered with a waterproof or bed bug cover. The mattresses can be rolled and vacuumed which saves a lot of transport costs.
