This mattress is exactly what you expect, comfy, fits well on the bed I purchased from this site and also is a decent height.
Unfortunately we didn't receive very good customer service from way fair, the product came two days after it said it would come, and we only received one of three packages... The next day the rest of the order came but had pieces missing, to which we were told would take weeks to receive. After complaining about the time it would take to arrive and letting them know we had just had a baby and guests were having to sleep on the floor we were told we could have £10 back but would have to buy the missing pieces our self. 
Very happy with the bed, very disappointed in wayfair.
