Well constructed for the most part. The instructions are quite bad so the first step is to empty everything and count all your nuts & bolts, and account for all your parts to get an idea of how things should fit together. All the bolt quantities should be even (4, 10, etc) with matching nuts & washers. 1odd long/skinny bolt for handle. Everything went together well and the seat is quite sturdy once assembled. I’m 5’11” 205lbs and the seat rolls along nicely in our yard while weeding. I’d recommend this item. Less expensive than the one I saw at harbor freight with a couple extra features. Assembly time was about 30 minutes with the use of the cordless ratchet.
