A monitor arm can solve two common desk problems at once—a screen that sits too low and a stand that takes up useful space. This is exactly what the Huanuo FlowLift Pro Single Monitor Arm is designed to do. Through June 22, the arm is priced at $29.99, down from $49.99, and clipping the on-page Amazon coupon and applying code OFORSXRF brings the final price down to $18.50. The discount gets even better during Prime Day, from June 23 through June 26, when the listed promotional price drops to $25.64, and the same coupon and code bring the total to $15.89.

The FlowLift Pro lets you pull the screen closer when you're working, push it back when you need more desk space, or rotate it vertically for reading long documents, coding, or managing spreadsheets. It also makes it much easier to position the monitor at eye level or wherever works best for you. Setup is fairly straightforward, provided your monitor uses a standard VESA mount and falls within the supported size and weight range (13- to 32-inch, weighing between 4.4 and 19.8 pounds).

Huanao also has a FlowLift Pro Dual Monitor Mount for people who already use two screens. Like the single-arm, it supports two 13- to 32-inch monitors, with the same 4.4- to 19.8-pound limit and mounting requirements for each display. Through June 22, the mount is listed at $53.99, but clipping the on-page coupon and applying code F9943ARW brings the final price down to $29.87. Interestingly, the Prime Day promotion isn't quite as good—from June 23 through June 26, the list price drops to $44.99, but because the promo code discount falls from 28% to 25%, the final price rises to $33.74. All things considered, the pre–Prime Day deal is the better value for the dual model. 

There are a few compatibility considerations: The single-arm model isn't intended for particularly heavy ultrawide displays, and both mounts require a desk that can accommodate either a clamp or grommet mount. Huanuo also recommends mounting them only to wood desks between 0.59 and 3.54 inches thick, so glass tops and thinner composite desks may not be ideal.
