I used to refurb Airbnb rooms. They always bought this trash. I put together fifty of these, give or take, and at least half of them had to be repaired or replaced. In the end, the owners all started buying actual bed frames.
If you are big, don't buy this. If you're 'rough' at all in bed, don't buy.

Although a good price, I wouldn't expect this to do a very good job. Zinus box steel products are pretty flimsy.

Isn't the size wrong? At 80x80" this is bigger than Queen (which is 60x80)

I was very interested until I saw what it is. My in-laws have one of these (very similar), and it's absolute trash. It would come apart no matter who climbed into the bed with a *THUMP* as the one of the joints slipped. There's nothing holding it together other than notches and tabs that loosely fit. I had to zip tie the pieces together in several places to make it work. Hard pass.

Pretty negative comments here but Amazon ratings seem fine

How is that a box spring? Looks like a foam mattress platform

Probably "global" ratings. Also probably heavily padded by people hired to bring up a sellers ratings so they can sell more garbage than the next guy can.
