Both protectors provide high-quality protection for a number of different factors. The choice will most likely come down to the preference for a quilted feel or a thin and less noticeable feel.

It’s also worth remembering that the Purple protector fits mattresses up to 13-inches while the Casper protector can go up to 16-inches thick.

Neither protector will completely protect against bed bugs since they are both five-sided (meaning the bottom side of the mattress is still exposed).

Both are machine washable and under $100 for a Queen size, making them excellent values.

Because I have a Casper mattress, I really enjoyed the feel and protection that the Casper protector provided. I also like saving money and it felt like I was combining a mattress pad and a mattress protector in this soft and quilted product.
