Hyde and Sleep mattresses are worthless after only 2.5 years. It was a bad decision since day one, as it is not as breathable as the company promises. It makes you feel very hot. Now, after only two and a half years of use we will have to throw it away, as the foam has lost its shape, it is bumpy, and I wake up everyday with pain in my neck and back. We bought it directly from their webpage and it does not exists any more. I cannot found any contact from the company, only distributors. We spent £600, and it supposedly had guaranty for 10 years. But now chequing my mails I realised they never sent a an invoice or information in the guarantee. They only sent the order summary. I feel cheeted!
