All Squirrel mattresses and seating are designed to be easy to assemble and consist of two components; the mattress base and the digital pump. In general, terms the mattress is unpacked and laid out on a suitable bed frame and strapped down. The mattress is then connected to the pump, the pump to mains power and then switched on. Depending on the model of mattress the correct weight and modality of use is then selected. The instructions for use (IFU) must be read and fully understood before using any Squirrel active (pressure redistributing) mattress or cushion.
