Aimjerry 3pcs Rattan Mattress Topper Pad Cooling Summer Sleeping Mat and Pillow Shams Sets (Full, Brown 2)

I bought it for the summer. It feels cool. However, even the extra firm mattresses in the U.S.A still can't hold it flat. It bend it when I tried to get on the bed or lay on top. It work good on the hard floor though. I only used a week, then have to roll it and put it in the closet. Too lazy to return it.
