Medium to firm matress with a nice depth.
I must admit its quite a warm mattress.
i needed to buy a mattress asap so didnt shop around however as my previous one was 12yrs old of  ourse im hsppy. Spending that little extra £ was definitely worth it.
I have no problems except would say dont always trust the text messages and emails from Wayfair- at 1 point they messaged saying they had it ready for delivery then there was one saying they havent received the goods at the depot....
