Bought a gel bed in February 2019 , have turned it every six weeks like instructed , now we have what I can only describe as a large jumping the middle of a king size bed a lot higher than the two sides , it’s impossible to sleeping the middle of the bed as you just fall to the sides . I called bensons as when I purchased the bed the reason I went with this company was the guarantee which isn’t worth the paper it’s written on . 15000 bed not even lasting one year disgusting , I will be seeking legal advice or contacting trading standards . My advice go to another shop .
