Versatile Fit for All Sleep Positions

With its optimal thickness, a 3-inch topper works well for all sleep positions—whether you're a side, back, stomach or multi-position sleeper. It provides enough cradling comfort to relieve pressure points while offering sufficient support to maintain proper spinal alignment throughout the night.
Ideal for Couples

For couples with different firmness preferences, a 3-inch topper provides a compromise that suits a wider range of needs. It offers more pressure relief than the 2-inch version for those who need it, while still maintaining a firm surface for those who prefer more support. Most 3-inch toppers come in a Twin XL size, which is perfect for one-half of a split king mattress.
Supports Recovery

A 3-inch layer of memory foam offers joints and muscles enough cushioning to help with recovery from daily wear and tear as well as more strenuous activity. It’s ideal for older individuals dealing with chronic pain and active persons seeking relief after exercise or long days on your feet.

Integrity to the Edge

Details Matter

Three inches of high-quality foam form a stable, supportive layer that reduces sinking and eliminates the "dumped" feeling when sitting on the edge of the bed. This added stability ensures consistent, even support across the entire mattress, allowing you to feel comfortable no matter where you lie. If you're looking for a topper that offers both enhanced comfort and durable edge support, 3-inch options offer an ideal balance for long-lasting stability and restful sleep.
