Hi Two weeks ago I fell prey to a doorstep saleman who had some mattresses 'left over' after a delivery in the area. I purchased a king size 'PERFECT SLEEP' Memory Dual Orthopaedic Mattress which I was told retails at £795. I paid £150. Firstly, I didn't realised it was an Orthopaedic mattress - can you explain what difference that makes?

Secondly, I have slept on memory foam before and this doesn't feel the same. It is quite springy and I feel like I'm laying on top rather than sinking in to it. Therefore the small of my back isn't supported at all. I am quite a small, light person. How can I find out what the composition of the mattress is?

I'm doubting that the retail price reflects the quality of this mattress and that I've been misled - I think it is sprung with a layer of memory foam (there are no details on the label and the company - Brooks Durest Beds in Leeds) can not/will not tell me) What should I have got for a mattress supposedly worth £795?

Any information would be appreciated. Many thanks. a
