TPU vs Vinyl Mattress Protectors

TPU and vinyl/PVC are both used to create liquid barriers, but they are different materials and should not be treated as interchangeable labels.

Focus on the actual product specification

Instead of assuming one acronym is automatically “safe” or “unsafe,” identify the membrane, any published chemical exclusions, and independent certification claims that are relevant to your priorities.

Why shoppers compare them

Many organic-cotton protector brands specifically advertise waterproofing without vinyl/PVC, which makes TPU or polyurethane membranes a common alternative construction.
