This is the second one of these that we have bought.  The queen was not purchased from Wayfair but we liked it so much we purchased a king too.  Unfortunately the king bed is too big for the mattress and I've heard this complaint before.  I was hoping it was an error but the frame is about 4-6" too big which kind of looks stupid and is a danger if you or your pet gets a leg stuck in it.  That being said the bed is sturdy and has extra support legs that other beds don't seem to have. Had I known it would be too big I would not have purchased it but it's too much trouble to take it all apart, ship back and wait for another proper sized bed.

Pros: Solid and sturdy
Cons: Too big for a normal king mattress.
