Depending on which frame style you choose, Uplift also sells an under-desk hammock that can attach to the frame for George Costanza–esque under-desk naps. The list of other potential add-ons and accessories is frankly longer than a diner menu, and includes everything from a bamboo desk drawer to a magnetic cable-organizing channel to power grommets that let you plug in a phone or laptop right on the desktop.
