After doing some research into modern mattresses, I liked the idea of a memory foam/spring free one. The overall reviews were positive, so I took a risk and purchased the Hyde & Sleep Raspberry mattress. I was so looking forward to getting into bed that night, for a decent sleep.... After a few hours tossing & turning, managed to have the most fragmented, uncomfortable nights sleep ever. The mattress is so warm and stifling, bearing in mind we had slept on it during a cold, winters night. God knows how anyone could sleep on this in the height of summer. It's a well-made product, I can't knock that, however, my girlfriend and I couldn't get along with it.
