Ordered these chairs (set of 4) at a great price of $156 (using 12% off coupon code). Free delivery was quick and items came wrapped pretty well and in good condition, but all the hardware plus assembly instructions were missing! I opened up an online chat with Great Offer Stock customer service and the friendly rep was very apologetic and offered to reach out to the warehouse (manufacturer = Modway) and get the hardware mailed to me in a few days. I needed the chairs for a party the following day, so this was not going to work. She offered to have the warehouse send assembly instructions via email so I could go to Home Depot and purchase the hardware myself. When I asked about getting reimbursed, she generously offered to credit me $35. I received the assembly instructions several hours later, but it was just a diagram, with no measurements for exact screws/bolts needed. I had also tired to find instructions online with no luck. Turns out Modway has a warehouse about 10 minutes from our house (though the chairs were delivered from Compton, CA!). My husband called Modway customer service (while in their parking lot) and said they could not help in any way. He wasn't even expecting to get the hardware, just measurements or model or something to help him buy the right screws! He ended up just hauling a seat and frame to Home Depot to try out different ones until finding one that fits. After 20 minutes of fiddling around with a variety of sizes/lengths, an employee suggested it might take a METRIC sized screw. By the way, the metric ones aren't even located in the same aisle and aren't available as loose pieces. He finally found something that fit and bought 8 bags (2pcs each) of Everbilt Cap Screws M6 - 1.0X16mm / Model #802178 / SKU#307239 plus a bag of 1/4inch flat washers. He said the chairs were pretty easy to put together with a socket wrench.
I only sat in the chairs for the first time tonight and they seem pretty comfortable. The base of the seat is wider than expected, which is nice. The blue color is great and the plastic does not seem flimsy, though it has some give (which probably lends to the comfort factor). Hopefully the hardware holds up! I'm giving these 4 stars simply because I haven't tested the durability and comfort of the chairs over time.
