Suggestion:

Please be clear that this mattress is a hybrid spring/memory foam mattress.

Update. I am pleasantly surprised at how comfortable this mattress is. As a loyal user of old school, very firm, spring mattresses, I am not used to NO SPRING NOISE when moving...even if you don't share a bed with someone, this is actually really nice! And it's really firm. I guess the last test is comfort during the hot summer months, but I think that hybrid will be the way to go from now on. 
Also it would greatly help if you could let us know how to get the rolled up, compresse mattress out the the box, and onto the bed frame, to facilitate removal of double plastic packaging before the mattress totally decompresses!

I started to panic as I heard the sound of air escaping the packaging and the mattress decompressing while I was still trying to remove plastic and mount the mattress on the bed frame myself (as I am old and petite!!)
