Will a Fat Boy Improve Your Performance? Read Reviews You know that if a mattress is a Fat Boy then it will perform. Please click on the Fat Boy tab above for full details. The violet mattress contains 1000 individually pocketed springs. The springs are not joined to each other so that they can work completely independently of each other & adapt to the contours & shape of your body. This means that the mattress will support your entire body from head to toe. Pocket sprung mattresses are widely regarded as the most supportive mattresses available. In true Fat Boy style there are then some really chunky comfort layers on top of the springs. With the violet mattress the comfort layers are hypoallergenic & resilient “rebound fibre”, reflex foam & a soft polyester layer stitched into the Cool Plus fabric to create the most sumptuous sleeping surface imaginable.
