I've bought 3 x panda toppers. One for myself whilst I was undergoing chemotherapy, one for my young son because he loved mine so much. The other for my mum however she didn't find it was comfortable however she is suffering from cancer in the bones and thought it would help, but was just too soft for her. We took advantage of the 30days trial which was great and no hassle at all returning for refund. Would recommend panda to friends and family. Even if it is not for them after the 30days trial is worth purchasing. I'm still delighted with my topper 6months on
