I had ordered the tray for my daughter. 
1. The colour, of the mattress, is as the pictures display.
2.. Comfort, indeed the comfort thus far is similar to some hotels foam mattresses {once equipt with box spring and a cheap 6" matress}
3...Longevity, the mattress seems to be well made, thus far, it may withstand the test of time and the horrible dooms of sagging.
4....Functionality, the design is good, however, due to the vacuum-sealed packaging, the mattress has a slight bend at the top right corner from the logo designed.
