Place the TopAire Topper on top of your mattress, with the valves facing UP toward the ceiling.

Uncap the valve and insert the included Lightning Fast Express Pump into the valve and lock the pump in with a twist.

Flip the switch on the Express Pump to the ON position and wait until TopAire is fully inflated. Repeat on the other side.

Before replacing the cap on the fill valves, press and hold the valve's button to slowly release air until you've reached your desired firmness level.

Cover both TopAire and your mattress with a single fitted sheet, securing TopAire and preventing it from moving.
