Good points... Good value for money as I paid half original price and Wayfair delivery was far better than anticipated after ordering over the tel having spoken to a v nice member of staff who answered all of my questions before I placed my order as I said I was concerned about the previous reviews 

Bad points... the one question I forgot to ask was about the length which is a couple of inches too short in comparison to other mattresses so it doesn’t actually fit a double bed length, hence only the 4 stars... 
One review said if you can afford a better one then I agree bc of the length but it is much better than my previous memory foam mattress so it’s an improvement
