Oh my what’s job. This metal box spring arrived fast and was boxed well from the outside. Once opened and putting together we realized some of the pieces were bent. With the bent pieces it was very hard to get the screws in. The instructions are horrible but we did get it together. It took two of us with the little picture instructions and bent pieces but we finished. It does fit very well in the full size bed and holds the mattress really well. With the horrible instructions and hard to fit screws it did take a while. This is why it got 3 stars, bad instructions and hard to put together. Because it fits the bed frame so well and will last for years to come it got 3 stars instead of 1. If you have the mangirl power and lots of patience then it is definitely worth the buy.
