If you're looking for a very very very firm and sturdy mattress as you always sleep on your back - then you won't be disappointed - this mattress will give you that support. That's the one! 

However, if you like to occasionally sleep on your side - you should probably consider something a bit more medium. Unfortunately, I had to return the mattress because it was just too firm for sleeping on the side (even with two thick and soft toppers). We were waking up tired with all sorts of aches and, literally, bruised hips and shoulders. 

But, in 100 days, mattress hasn't changed its form at all - the construction inside seems great and you won't bounce around when your partner is turning or moving. So, for back sleepers who need a lot of support - it's brilliant. For side sleepers - no.

Return and refund with Wayfair were easy, quick and efficient. Thank you for the great service and support.
