These are the worst chairs I have ever purchased the bolts were to short had to buy new ones in order to put together. The netting was terrible to try and line up on the bars to attach to unit. These should come with netting attached to bars to eliminate the hassle what a nightmare. I paid good money for these chairs and to have  a product that takes forever to  assemble is not worth the money the will probably fall apart the first season used. This is the first product from Wayfair that I purchased that was awful and I have ordered a lot. Don’t waste your money and listen to other reviews that gave this product star reviews I did that already. The vendor needs to find away to assemble unit for the customer I am very disappointed with these chairs.
