My original review was 5 stars but I am reducing the amount of stars as I am so incredibly dissapointed!!! 
It is so uncomfortable to sleep on, even with a topper I wake up feeling like my body has been beaten up. I wish I had slept on it sooner as now it's too late to return it. To add insult to injury, I see they are saying original price is £569 and on sale for £509, when I got it they said original price £900 and something marked down to £609, so I've actually paid £50 more than the current "original" price. 
I thought Wayfair was a reputable company - right now I feel so ripped off. So, no, I would not recommend Wayfair based on this experience!!!

I have now ordered an extra deep topper - hopefully this will make it more bearable to sleep on.

Sadly, this has been a very, very expensive learning experience.
