INRail Support Foam Inserts   

The design of AIRPRO Support Foam Inserts is to fit inside the zippered cover, on top of the air chambers Inside foam rails. The Block design provides even support for each part of your body as well as easing the transition from the left side to the right side of your Sleep Number® bed.


NEW - Now you can add a layer inside the foam rail with INRail Foam!


This INRail Support Foam Insert can be used to Prevent Bed-Sagging in Sleep Number® beds.


The zippered cover of your Sleep Number® bed can stretch out after years of use much like your favorite pair of jeans. The fabric can stretch out causing the sides of the bed to bow out causing bed sagging and adding a INRail Support Foam Insert into the inside of your zippered mattress cover can help reduce these effects.


Block Foam Design Medium Density Foam provides pressure point reduction between you and the Air Chambers.



This Foam Insert is designed to prevent bed sagging in the support section of Sleep Number® Beds.
