The Purflo Fix accessory is an anti-bacterial and fully washable underlay that fits between the base of the mattress and the top of the cot base. It absorbs any ‘leakages’ that may occur from your baby helping to catch any spills or nappy leaks.  Using the PurFlo Fix mattress underlay with the PurFlo Mattress maintains the breathability of the mattress and contributes to a healthy nights sleep. The pad is equipped with a waterproof base below a breathable Silvercare pad designed to help keep it odorless as well as anti allergenic and skin friendly. Fits under both 140cm x 70cm and 120cm x 60cm PurFlo Mattress.
