I purchased this Down Alternative Mattress topper for my 8 yr old son. We recently set up a loft bed in his room which needed a different mattress than the one he previously had in his old bed. The mattress seemed thin and my son has been asking for a pillow topper like Mom & Dads (our topper came with our new mattress). So when I saw this I decided to give it a try and boy am I glad I did! The topper is light and fluffy and, according to my son, 'perfect' to sleep on. The topper is a little shorter than the mattress, about 4-6 inches. This was easily remedied by sliding the topper closer to the bottom of the bed and giving my son an extra pillow to use at the top of the bed, problem solves.
