KINGYES 6 Piece Patio Dining Set, HDPE Outdoor Table and Chairs with Bench, Aruba Blue

Robustly constructed. I don't doubt the 330 lbs. rated capacity. If you needed it to carry more weight, you could easily reinforce the chair with a bracket under each corner of the seat frame. For a few dollars in extra hardware, the chair could easily support 500 lbs. (In fact, I believe the original chair might support 500 lbs. - but only under static loading conditions. No bumps, sways, or jostling.) And speaking of weight, these are not lightweight portable plastic chairs. They are about as heavy as wooden chairs of the same size. They are surprisingly hefty and they are not stackable for storage. I wouldn't recommend using them for casual picnics or even weekend camping. As for size, these chairs are definitely bigger than any of my other plastic outdoor/patio chairs. I'm 200 lbs. and the chair gives me ample wiggle room, I'd estimate that it easily fits someone 250 lbs. It would probably be adequate for a 300-pounder, but I'm not sure about that. My main concern when purchasing this chair was about the hardware. A lot of companies cheap out on the hardware by using inferior quality or too short bolts and screws. The hardware for this chair is all stainless steel, properly sized for their loaded condition, and of good quality. The retaining nuts are "lock nuts", a convenient feature to ensure bolts stay in place. Another concern was assembly instructions. Many times the instructions are too small, too poorly illustrated, or make no sense. Sometimes, instructions are not even included. The instructions that came with this set are well-illustrated, readable, and easy to follow. Lastly, I was concerned about difficulty in assembly... whether holes properly aligned or whether I would need to do pre-drilling. No problem here at all. Everything lines up perfectly and no drilling required. And while I tightened everything "finger tight" during the assembly, before finally tightening everything down at the end; I think I could have foregone that extra step because everything fit right in the first place. I purchased a pair of these chairs for $110 including taxes and free shipping. I think they are a bargain at that pricepoint. Unlike other flimsy plastic patio chairs which last 10-20 years, these chairs are built to last a lifetime.
