unpacked this mattress almost 5 full days ago and it has expanded nowhere near where it should have. 23 of the mattress are appx 8 out of 10in with the other 13 is less than that. Additionally, all four of the corners have expanded to 5in or less. Right now it is not possible to sleep on it due to this uneven distribution. The mattress doesn’t really have a “gel-like” or memory foam feel either. Kinda just feels like a sponge. Will contact Wayfairmanufacture for support and update review accordingly.
