When I first installed this product (which was not so difficult if you don’t tighten until the end) it came out very nice and I was satisfied with my purchase (despite it being a cancerous material which states on the label) A week later my boyfriend sat in the middle part and it bent like it shows in the picture. We tried to adjust it but I keeps bending now every time someone sits on it and it’s very uncomfortable for this reason. 

For now we will keep this product but once we move we will not continue to use it due to its toxic material and because it’s very lowquality.
