Durability is a double-edged sword; while vinyl is designed to be waterproof, it can still tear or puncture easily if not handled carefully. This can lead to the cover failing to protect the mattress from spills or accidents.

Fit issues can occur, particularly with thicker mattresses that may not be well accommodated by standard-sized covers, resulting in an improper fit that can lead to slippage. This not only affects the protective benefits but can also create discomfort while sleeping.
Maintenance and cleaning can be a hassle as vinyl often requires special cleaning agents and methods. Users must be mindful of how they clean their covers to prevent damage, which can be time-consuming and tedious.
