My wife ordered "Comfort Dreams EnviroGreen Crowned Low Profile King-size Memory Foam Pillow" which is 3.75 inches thick so I order this pillow which is supposed to be 4.5 inches thick. My pillow arrived in a package that was partially opened and decompressed. The pillow is thinner than advertised and less thick than the "Low Profile" pillow, even after the 48 hour decompression. It must be a defect in production because it also weighs about 1.5 pounds less than the King size low profile pillow. Don't order!
