I bought this king size mattress when Wayfair had a sale on, incredible value at just £199!! Much more on other sites or via silent night direct. 

My order came within 48 hours as promised and was vacuum packed so I was easily able to drag it upstairs on my own.  I was a bit worried about the potential smell that was mentioned in some reviews but I let it stand up against a wall for two days and left the window open.  I used the mattress after two days and the smell did linger for a few more days but it didn't bother me at all and now the smell has totally gone:) 

This is my first memory foam mattress and it did feel a little strange for the first couple of days but now it's so so comfortable, I love it!! And I am not experiencing any lower back pain anymore as I did with my old mattress. 

Would highly recommend
