Purchased this to go with our new king bed frame: 
1. Pro: Wayfair customer service representative is great and helped a lot on the phone; the Silentnight vacuum package is efficient solution if you are moving to the new flat
2. Cons: This Mattress itself is too thin, we did not feel that solid, and eventually we bought another memory form topper to go with it ; Be mindful that in the beginning, memory foam mattress comes with some "plastic" smell and the smell will be gone after few days
