This one's a KEEPER!

Crazy-easy to "assemble" and highly recommended. It does lift the mattress 14 inches off the ground, which is a pretty generous height, if you're using a thicker mattress like the one I've got here. I even thrashed around on it to see if I could get it to squeak--it remained silent and gives a very confident feel.

THE MATTRESS: The label states that this is "Innocor Comfort." Here's some backstory I found on the web: "Sleep Innovations became Innocor Comfort, the company's consumer products division. It manufactures foam products, including mattresses, pillows and mattress toppers under the Sleep Innovations, Novaform and Serta brands."

Our mattress does not mention a brand other than Innocor, and I wasn't able to find anything on the internet that looks identical, so it may be a discontinued item.

It is 14" deep, and very impressive.

Costco apparently carries Innocor (but not under that name!), so good luck to all of you!
