It's firm, but soft, and lives up to the promise of a cool-but-not-cold night of sleep. Edge strength is a little lacking, but on a Queen or larger, not a problem. We got the soft stretch sheets as well, which have a nice weight and breathe well. And finally we got the harmony pillows, which are similarly firm-but-flexible and cool all night. Packaging kept the bed and foundation safe in the mail, and it wasn't hard to assemble. Full marks for quality and comfort. The full package was a great value.
