Tuffcare's TG10 Gel Overlay is an incredibly easy to install first line defense for patients who are in danger of developing bed sores. Snap the TG10 over your current mattress with ease and enjoy three oversized sections full of 2" gel. The gel layers provide unsurpassed pressure reduction while also preventing the possibility of bottoming out. The TG10 features a 20mL vinyl bladder constructed to prevent moisture transfer and evaporation. Its high density pinpoint foam layer reduces heat and moisture by encouraging circulation of air between the patient and the gel layer. Easily remove or replace the low shear nylon cover by using the TG10's convenient zipper.
