Applying gentle but firm pressure helps ensure a secure fit between pad and frame.

If your existing foam pad has degraded, this all-in-one unit is the ideal fix.

Why Choose This Replacement Pad?

The original PostureFit Butterfly Pad was engineered to deliver targeted lumbar support to reduce fatigue and promote a healthy spine alignment. Over time, the foam or plastic can wear down—this replacement part restores both the look and functionality of your chair at a fraction of the cost of full replacement parts.
