VEVOR Hospital Bed Mattress, 159 kg Load Capacity, Long Term Care Pressure Redistribution Medical-Grade Foam Mattress, Waterproof for Bedsore Treatment Nursing Homes and Home Care, 914 x 2030 x 153 mm

I would like to buy these mattresses to install in a sailing boat. I will have to cut the mattress to a custom shape and restitch the cover. My question is, is it possible to cut the foam mattress? The only concern I have I that in the description there are gel pads.
