Hi - Current bed is a Sealy Posturepedic Regatta 8/10 years old. It's been good. Looking at replacing for about £1k. We are both in the 10-11 stone bracket and are mainly side sleepers. Thought about Hypnos but reviews are very mixed especially relating to after sales! Do you think the Origin Pockets 1500 will be ideal? Will it last 8/10 years? Do you need a topper? Many thanks Martin
