Perfect!
Just what I needed! I just bought a new mattress, and it is just a tiny bit too firm when I sleep on my side (same thing happened the last time I got a new mattress). So I did what I did the last time I got a new mattress and got a memory foam topper. Only this time, I didn't need much additional padding to get the mattress into my comfort range (last time I went through a 2", and then ended up with a 4"" thick topper -- which created all sorts of problems with sheets fitting). I didn't even think i needed a 2" topper, and was searching for a 1" topper and found this one at 1.5" thick. It was reasonably priced, and even better, I got it the same day I ordered it! I opened it up and it expanded fully within an hour and even better, it had no unpleasant order at all! The instructions stated to let it sit for 24 to 72 hours to allow it to fully expand, but I put it on my bed the same day and slept on it that night. The 1.5" thickness was just perfect, adding enough extra cushion that I slept through the night without any discomfort to my hips! Now I am set for the next 20 years (I was at 22 years on the mattress I just replaced)!

Perfect thickness to transform a mattress
Before putting this pad on my bed I couldn't sleep more than a night or two without back pain. Now I've been able to sleep in my bed for over a week straight and I feel great in the morning
