Both protectors provide high-quality protection. Your choice will most likely come down to whether you want a quilted feel or a thin and less noticeable feel for your protector.

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.

Because I have a Casper mattress, I really enjoyed the Casper protector. 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.
