Replacement INRAIL FOAM INSERT for Sleep Number® beds

  • FOR USE WITH Sleep Number® Beds by Select Comfort® - Fits inside zipper cover on top of air chambers inside foam rails. 
  • We do not sell Select Comfort® or Sleep Number® Brand Support Foam Inserts. 


The design of INRail Support Foam Insert is to fit inside the zippered cover, on top of the air chambers AND Inside the 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 and stop bed sagging in your Sleep Number® bed.


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.
