We've had our Cal-king GhostBed All-in-One Foundation for about a month now and it's great. We love that it was delivered right to our door, and that it was SUPER easy to put together. It's light, but sturdy. We like knowing that our GhostBed mattress is resting on a foundation that was made especially for it - no need to guess whether our GhostBed mattress will be adequately supported. Reasonably priced, too.
