Frequently Asked
Questions
A mattress topper adds extra cushion and rise—perfect for those who need a plush surface for sleep. Our Casper Mattress Topper is designed with supportive foam for maximum comfort.
When it comes to choosing a mattress protector, the two main considerations are thickness and material. These will impact your bed’s functionality, temperature, and comfort. Ask yourself these questions as you browse:
No matter your sleep needs, choose a topper that enhances your sleep comfort. And always match the sizes carefully—even twin or full size mattress toppers won’t fit perfectly on a twin XL bed the way a twin XL mattress topper will.
Advanced synthetic materials like foam and polyester create uniform comfort and durable support than natural materials like feathers or wool. At Casper, we’ve enhanced our topper’s structure with a latex foam interior and a polyester cover for the perfect balance between softness and support.
Most toppers range from two to four inches in thickness. Anything less will hardly be noticeable. Anything more can affect the structure and support of your bed. Our topper sits at an optimal three inches high with three individual layers of premium, plush comfort.
The different materials provide different benefits. Memory foam is a viscoelastic material in mattress toppers that sensitively molds to your body—it’s left with a “memory” of your outline—to optimize comfort and proper alignment. A viscoelastic memory foam layer provides the right amount of support.
Gel mattress toppers offer slightly less structural support but they do have greater cooling abilities. To enjoy this benefit without sacrificing comfort, pick a memory foam topper with a perforated design for increased airflow — like Casper’s Mattress Topper.
