Its not a 2 inch topper.. and I left it sit out for over 24 hours before using it and it still has a giant crease going down the length of the center .. As well as the bottom portion seems to not be able to inflate much at all and acts like a squashed piece of bread. You know the squish effect Im talking about .. The places it has fully inflated is only 1 inch at best nowhere near 2 inches.. Edit I have just read through the reviews.. I wish I had seen them before purchasing this .. Seems to be an ongoing problem with this topper .. Serta and Wayfair need to do better ... Knowingly selling faulty products is bad business ..
