Query: Very good topper!

I bought this for my husband's hospital bed and added it to another piece of regular foam I was already using. I expecially liked the idea that it was ventilated. I really couldn't afford to get what I'd like to have bought (a Tempurpedic mattress, even if they made that size!) so I just kinda built it up to make it as soft as I could for him. The point is that is that he is very happy with it and that's what really counts!! I would recommend this product or the 3" which I see they also make as long as they are ventilated. I think that makes all the difference and, believe me, I've tried several products!This is great!Judy SnithSleep Studio 2-Inch ViscO2 Ventilated Memory Foam Mattress Topper, Twin XL
