With this topper the standard mattress is a height of 18" making it the perfect height to get in and out of bed with ease. After cautiously opening the box and cutting the sealed bag all I needed to do was lay the topper out on the bed and within two hours it finished rising however the directions recommend giving it two days to fill and air out, it does have an odd smell so I do advise opening a window. Since this is a mix of gel and memory foam (with ventilation holes) it seems to be a little cooler than the traditional memory foam yet still offers the feeling of floating as it relieves the pressure of your body's weight. This is very comfortable and allows for gentle movement while still supporting the pressure points leaving me with a better night's sleep without the usual tossing and turning.
