In the top left hand corner one of our mattress writers performs an effective sleep space test on the DreamCloud Classic mattress. In the top right hand corner you can see our pressure relief weighted indentation test in process, where we are using a standardized stack of weights to measure how much the mattress indents (how well it contours) and how quickly it recovers (how responsive it is). In the bottom left hand corner another our of mattress testers lies on her side on the Saatva Classic mattress during a pressure relief test, with a digital laser projecting a straight line onto her back so we can assess how well the mattress supports spinal alignment. In the bottom right hand corner, one of our mattress testers lies on a hybrid mattress during a thermal regulation test.
