After purchasing this GEL topper from overstock.com, I was very impressed with the construction of the topper and as a result have had my sleep turnout for the past few weeks make this product very worth while. It was a fairly heavy package and getting out of the box requires some amnipulating if you are not a big person. Once I spread it on the bed, it did take about 24 hours to fully expand and settled to its claimed height from this website. After this happened I have no complaints since I own a king size bed and have plenty of space to spread my 6'6" frame out. It is very comfortable to sleep on with just the right amount of firmness and the perfect level of cushioning for my weight and any more pounds I may put on in the future. The topper did elevate my bed much higher than I had previously thought and this was for me a non-issue since I am so tall but will make it a challenge if others have small pets who enjoy jumping up and sleeping on there bed. They may not get up there so easily. Another wards it does make the bed noticeably taller for the smaller stature individual. The GEL technology definitely seems to be a bonus since the bed is generally cooler and the 1.5 inch topper cover that comes with it is a nice addition for the extra padding and cushioning too. So, all in all, worth the money from my perspective.
