  • Never recieved, never moved in transit.
Not the worst, but definitely get what you pay for. "Non-slip bottom" but mattress needs to be adjusted every single day, no joke. Stitching is already coming out of the top layer, even with a sheet kept on it religiously, after not even a full month. Better than sleeping on a "hand-me-down" mattress, but with the aggravating shipping of losing the mattress till the last 2 days and the quality unraveling as it goes, choose another option. ... show more
