Who Should Buy the Casper Comfy Topper?

Back Sleepers:

Sleeping on your back evenly distributes weight and minimizes pressure points, ideal for spinal alignment.

However, back sleepers often need extra support to maintain the lower back's natural curve. A mattress topper with firm support can prevent the spine from sinking too deeply, promoting better posture and reducing back pain.

Side Sleepers:

This position requires additional cushioning in areas like the shoulders and hips.

Side sleepers benefit from a softer mattress topper that molds to their body's contours. This topper provides relief at pressure points and aligns the spine horizontally. Without adequate support, side sleepers may experience joint strain and discomfort.

Stomach Sleepers:

Stomach sleepers are often the least recommended position due to the significant strain they can put on the neck and back. Because of this, stomach sleepers need a firmer topper.

This prevents the pelvis from sinking too far into the mattress, which can cause spinal misalignment. A firmer mattress topper helps maintain a neutral spine posture, reducing the risk of pain and discomfort.

Regardless of your preferred sleep position, the Casper Topper is a versatile solution that adjusts to provide lumbar support and a flat surface. It’s a snooze-worthy upgrade that rivals Nolah’s topper and other sleep innovations, ensuring it caters to your needs.

Expert Tips: Maximize Your Mattress Topper’s Benefits

Want to get the absolute best out of your mattress topper by Casper? Here’s what sleep experts recommend to enhance comfort, cooling, and longevity:

✅ Pair It With Breathable Bedding
Even the best cooling topper works better when paired with breathable sheets and lightweight blankets. Opt for moisture-wicking cotton or bamboo fabric to boost airflow and prevent heat buildup.

✅ Let It Fully Expand Before Use
After unboxing, allow the mattress topper to decompress for at least 24 hours. This ensures the foam fully regains its intended shape and provides optimal support right from the start.

✅ Rotate It Regularly
To prevent body impressions, rotate your mattress topper 180 degrees every 2–3 months. This distributes wear evenly and maintains balanced support across your entire sleep surface.

✅ Keep It Clean and Fresh
Always use a washable, fitted cover to protect against spills, sweat, and allergens. Vacuum the mattress topper occasionally with a soft brush attachment to remove dust and maintain hygiene.

✅ Match It to Your Sleep Position
Side sleeper? Add an extra-soft pillow to cushion your neck and shoulders. Back or stomach sleeper? Pair the mattress topper with a medium or firm pillow to align your spine.

✅ Test, Adjust, and Use the Sleep Trial
Take advantage of the 100-night trial to test whether the mattress topper truly improves your sleep. If it feels too soft or firm, contact customer support for an exchange or adjustment.
