I bought this mattress after suffering through 2 Simmons Beautyrests that got depressions after 3 years and a Sleep-O-Pedic that got body depressions causing backaches after exactly 2 years.
I thought a Natural Latex, using the firmer Dunlop process would be firm... I was wrong..the mattress gave me a backache the first night.. I also had a hard time getting comfortable on it's dimpled surface. It felt as if the mattress was poking me in the back.. it feels a little better after 5 days, but I can still feel the pokes if I am on my back..my backache is pretty much gone though.

We are exchanging it for a Stearns and Foster latex to be delivered in 3 days..

Just bought the Body Rythms King Rejuvanate Box Top King, for 3000. It is nice and soft, however it sags under lower back after you break it in. It just started to do this after the first month. From day one this bed sleeps hot. During hot nights, it is very uncomfortable. like sleeping on a fire.

Totally satisfied with this purchase. I had NO adjustment period, I no longer wake during the night at all and as an added benefit that I was not looking to "fix" my "restless leg syndrome" went away.
