This mattress topper helped in me being more comfortable sleeping in my year old tempurepedic mattress.  In addition, the mattress topper stopped me from getting so hot with it being a barrier from sleeping on the hard foam itself.  The only thing I don't like is that the feathers will poke you sometimes and the mattress cover slips.  I readjust it every other day which is no biggie.  This is probably due to me laying on the bed in the evening to watch tv and getting up an down off the bed several times.  This causes it to move.
