Great Product
This all metal frame was easy to assemble and very lightweight, which makes it simple for one person to handle. This is the second Zinus frame I've purchased (the other was for a California King mattress). I highly recommend this product.

Definitely buy
Reading some of the reviews I was a bit worried but now that I have set it up and it's in the home I'm honestly so happy. I got the twin size for about 50$ , shipped in a few days, easy to assemble ( instructions are very clear and I only needed one or two glances ) , fits bed perfect. No complaints one bit and would buy for all my beds in the future!
