# Sit to Stand Desk Riser, Height-Adjustable Standing Desk Converter with Wide Keyboard Tray - Pneumatic or Electric, 32/36/42 in ## A sit-to-stand desk riser that works with the desk you already have This is a desktop converter, not a standing desk. It sits on your existing desk surface and lifts the top level, so you can move between sitting and standing without replacing your desk. The upper surface carries your monitors or laptop and the lower tray carries the keyboard and mouse, so both stay at sensible relative heights as you raise it. Six models are sold on this listing. They differ in three ways that matter: how wide the top is, whether the lift is pneumatic or electric, and how much weight the top will carry. Everything else is broadly common across the range. ## Pneumatic or electric The three pneumatic models raise and lower on a gas-assisted lever with a height-locking mechanism, so you set the height by hand and it holds. The three electric models use a motorised actuator with a push-button control pad fitted under the front edge of the top surface. The product photography for the electric models shows that control pad and a cutaway of the actuator inside the scissor frame. The pneumatic models are listed with a 3 inch gap between the top surface and the keyboard tray. The electric models are listed with a 4.5 inch gap. The pneumatic models are also listed with a slightly wider base at 30 by 16 inches, against 27 by 16.5 inches for the electric models, so the two lines take up different amounts of desk depth. ## Compare the six models Every figure below is taken from the specifications published on this listing. Where a figure is not published, that is stated rather than estimated.

A height range is published for the pneumatic models but not for the electric ones. And the 42 inch electric model is listed with a 36 inch keyboard tray under a 42 inch top, which reads like a carry-over from the 36 inch model. Both are flagged for the merchant to confirm. ## Monitors and mounting The listing states that the models support two monitors up to 24 inches each, or a laptop plus a monitor, and that they take low-profile C-clamp or grommet monitor mounts. If you use a monitor arm rather than the stock stands, check the clamp jaw against the 15.7 inch top depth before ordering. ## Materials The pneumatic models are listed with an engineered wood top on an alloy steel frame. The 36 inch pneumatic model is listed with a powder-coated finish and the 42 inch with a laminated black finish. The electric models are listed with a plastic, particle board and melamine top on an alloy steel frame, and the 42 inch electric with a steel frame. All six are black. ## Assembly The assembly images published for the 32 inch pneumatic model show three steps: install four rubber feet, remove the shipping tie, and secure the keyboard tray with four screws. Hardware and instructions are listed as included. Assembly is not separately documented on the page for the other five models. ## Shipping and returns Free shipping in the USA.
