Disappointed waited nearly 4 weeks for mattress only to discover it was not anything like the one in the picture. Rang Wayfair straight away who offerd a discount to keep it. left 72 hrs as says on packaging to gain its shape.After 3 days to gain shape the cover was loose and ill fitting and it was only 21 cm depth and not 23 as specified in Ad. 1st night of trying to use mattress was like being on a lilo in rough water or trying to sleep in a bouncy castle. Rang wayfair again to explain that i needed to return Mattress as needed a firm like i ordered and not soft and they agreed to return item and ordered me a replacement but will be another 3 weeks.
