Amazon special L-shaped desk with two risers. The vertical hutch-type riser is not included, but the keyboard tray is.
Structurally very sound, but the top surface is pretty stained and scratched. The power strip/charge ports work fine. The drawers are fabric, and the top one has gridfinity in the bottom (IYKYK), which is removable if you don't want it.
The table surface is 5/8" (15mm) thick. The risers are 7 1/8" (18cm) by 23 1/8" (60cm), with 4 1/2" (113mm) of clearance underneath. The risers are not attached to the table surface.
The keyboard tray slides fine, and can be height and tilt adjusted.
I'm pretty sure it can be assembled for right handed or left handed orientation, but you'll have to figure that out on your own.
Available on February 28. I'll have it mostly disassembled when you come to pick it up; it should fit into the back seat of a mid-sized car fairly easily at that point. I'm in a 3rd floor apartment, but there's an elevator and I have a cart.
