bought in October this year.
i have an older 2005 model of the queen sleep # bed and wasn't sure it would fit the pillow-top mattress but it does beautifully:)
the bamboo material is soft as silk and is very plush and comfy.
i usually have a heated mattress pad to go over the pillow-top for warmth in the colder months, but with the bamboo material of this cover, with an added cotton flannel sheet and a comforter, the temperature is warm and the heating pad is not needed.
great price and highly recommend!!
