On Etsy, every seller in the world seems to make a wooden monitor/laptop stand. If you're seeking an alternative with a lighter visual impression, a company called Heartwork makes theirs out of metal. Because they're made of 12-gauge steel, they can support 30 pounds across their 17" span, yet are ultra-thin--a shade under 1/8" thick.
They're powder-coated and sold in a variety of colors, in both solid and perforated options.
Reminding us that production methods are more expensive than materials, the solid models are $60 while the perforated models run $85.
