You should try them out. When I bought myself one I lay for a couple of minutes on each of 4 models to see if it's comfy for me.

But don't buy too soft mattress. It could seem really cool at first time but your back will hurt like hell next morning. Beside it's more healthy to sleep on a hard mattress.

Anyway all of mattresses I saw are two sided. One side is little softer then other. Test the harder side at the store (it should be comfy for you) and if after several nights your back will hurt - flip to the soft side. You need to sleep a several nights on the mattress as your back needs a time to get used to it.

Warning though: laying on a mattress for a few minutes in a shop != sleeping well on it all night for months.
