My honest suggestion is not to go for "Simmons Beautyrest Platinum" or other older models. These models being sold by "Sleep Savvy / Ackerman". I bought "Beautyrest Platinum" recently from "sleep savvy". Definitely it is not worth money I spent. Sales executive told it is Medium Firm and very good for the persons having Back problems. But, in my case it is reverse. Once we started sleeping on this new mattress, first impression was it is very hard. Everyday morning , when I get up, I was feeling severe back-ache. That time my wife was ignoring my complaints. After few days she also started complaining/feeling the same. So, we decided not to sleep on this . Moral of the story : Don't run behind the Famous Brands. Check the mattress thoroughly by trying different models and lying more time on the mattress. This is my real experience. Hope , this helps.
