Hmm that price makes me tempted to grab one for the guest room. Just hoping it doesn't show up bent or extra squeaky like some cheap metal ones do.

no way, $35.50 shipped for something that could finally get my spare room off the floor and into actual guest-ready mode, though i wonder how it holds up long term.
