Helping You Understand What’s Normal and How to Care for Your Mattress
At Sleepy Sal, we want you to enjoy the best sleep possible—and that starts with understanding how a mattress works over time. One of the most common things new mattress owners notice is the appearance of body impressions. These slight indentations are not only normal—they’re expected.
Why Body Impressions Happen
High-quality mattresses are made with plush materials like memory foam, soft fibers, and advanced cushioning layers. These comfort materials are designed to cradle your body, relieve pressure, and support proper alignment. As you sleep, they naturally respond to your body’s shape and weight, leading to visible impressions where you sleep most.
Think of it like breaking in a new pair of shoes—your mattress is simply adjusting to you.
Industry standard: Impressions up to 1.5 inches deep are considered normal and are not covered under warranty. They are not a defect or sign of mattress failure.
The Better Sleep Council notes that many of today’s top mattresses use advanced materials that allow you to move less during the night, which can make impressions form more quickly. But this is a goodsign—the mattress is doing what it’s meant to do.
