We chose this bc it was recommended (by WAYFAIR) for firmness, low motion transfer, and temp. It’s super bouncy and unstable, with sloping corners and edges. We can feel WVERY COIL, we unboxed it on 4 days ago, slept on it 3 nights, and it’s SUCH A DISAPPOINTMENT! My hips and back are screaming, and now we have to start from scratch! Garbage! NOT FIRM! NOT COMFORTABLE! Please don’t waste your time and money!
