6 Gauge Vinyl Bed Bug Mattress/Box Spring Cover by Hygea Natural - Waterproof Encasement- Perfect for Bed wetting (Full)

How do you choose a size?? it says size is xl twin california king. those are two vastly different sizes.

is it made with non-toxic products

Looking for: no cloth... only vinyl (or similiar) king 16" mattress zippered encasement. do you sell this? Also what gauge?

will this fit on a 9.5" thick mattress?
