Fills In Comfort Channel
Turns one half of the Comfort Channel into a flat mattress by closing the gaps and matching the support of the rest of your SONU.
Versatility For Other Positions
Helps with sitting up in bed if you don't have an adjustable frame, and provides more options for positions other than side sleeping.
Replaces Support Pillows
Switch between your existing Support Pillows, designed for side sleeping, and the Comfort Insert, designed to convert one half or all of your SONU into a flat mattress whenever needed.
Fitted Sheet Compatibility
If you use two Comfort Inserts to fill in the Comfort Channel entirely, you can then use traditional fitted sheets on the SONU mattress.
Smooth and Cooling Cover
Premium breathable material that is removable for easy washing.
