Step 2: Take the measurement of the depth of the chair, from the front rail to the back. This on measures 18" deep.
Step 3: Measure from the floor to the top of the deck. The ideal seating height is 19 to 20". This one measures 16 1/2" high, therefore we would order a 3" thick cushion to make the top of the cushion 19 1/2" off the ground.
Step 4 Take the same measurements on the old cushion.
It the cushion and the chair measure the same size there should be no problem. If you get a discrepancy of more than 1/2", please call.You would order a 18" wide x 18" deep, x 3" thick seat cushion.
Remember to measure twice and call if you have any questions!
