Purchased this bed as a replacement for a plush spring bed. Have also owned other memory foam beds in the past. About one month in now, this bed is high quality, very comfortable, edges are sturdy, heat dissipates quickly as promised with the cooling gel. I would give it 5 stars but it is firmer than expected (and firmer than my plush spring bed). Other reviews had called it too soft. Hoping it will still break-in and soften up more, but otherwise very happy with the bed.
