I got this mattress topper because a previously purchased on at another store was only 2" high and did not alleviate my hip and lower back pain when I slept. This product is much higher and provides plenty of comfort. Since I've used it, I no longer wake up in the middle of the night with pain from areas that have hurt due to circulation issues. I use the topper with the "tip" side turned down. I tried the other way, and it was a bit to "squishy" for me. Flipping it over gave me just the amount of firmness and comfort needed. Only draw back....my bed is higher now and one of my stockier cats now has problems making it on to the top in one leap:-)
