The Casper Original is a popular all-foam mattress designed for balanced comfort. It suits side sleepers who want pressure relief without excessive sink. Its standout trait is the Zoned Support system, which provides firmer support under the hips and softer comfort at the shoulders. This helps maintain proper spinal alignment.

How to Choose a Mattress for Side Sleeping

Side sleepers need pressure relief at the shoulders and hips. A medium-firm mattress often works best. It cushions without letting the spine curve. Look for zoned support or targeted comfort layers. Also consider your weight and sleeping temperature. Foam retains heat, but breathable covers help.

Understanding Firmness and Support

Firmness is subjective, but a scale of 1 to 10 helps. The Casper Original rates around 6. This is medium-firm. Support refers to how well the mattress keeps your spine aligned. Zoned support uses firmer foam under the hips. That prevents the midsection from sinking too deep. Side sleepers benefit from this alignment.

Materials and Construction

The Casper Original has three foam layers. The top layer is breathable open-cell foam. It provides initial comfort and cooling. The second layer is zoned support foam. It is firmer under the hips and softer at the shoulders. The base layer is durable support foam. Total thickness is 11 inches. This construction balances comfort and longevity.

Who Is the Casper Original Best For?

This mattress suits side sleepers who prefer a balanced feel. It also works for back sleepers. Combination sleepers can move easily on its surface. Couples appreciate its motion isolation. However, petite side sleepers may find it too firm. Heavier individuals might need more support. Consider your body type and preferences.

Comparing the Casper Original to Other Mattresses

Compared to the Casper Wave, the Original is firmer and less expensive. The Wave has more advanced zoned support and cooling. The Casper Original is simpler and more affordable. Against the Nectar, it has a similar feel but less sink. The Nectar is softer and better for strict side sleepers. The Original offers a more balanced feel.
