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.

When Impressions Are More Noticeable

You’re likely to notice impressions more if:

• You sleep on a Queen or King size, where the middle isn’t used as much
• You choose a pillow top, Euro top, or plush model with extra cushioning
• You invest in a luxury or high-end mattress with more comfort layers

Tips to Extend the Life of Your Mattress

• Rotate regularly – Turn the mattress head-to-foot every 3 months, especially in the first year.
• Use a supportive foundation – Slatted bases should have slats no more than 3 inches apart.
• Protect with a fitted mattress cover – A waterproof, washable cover guards against moisture, wear, and allergens.
• Smooth out the surface daily – Pull your fitted sheet tight when making the bed to help even out wear.
• Distribute weight evenly – Avoid sitting in the same spot daily or placing heavy items in one area.
• Let your mattress breathe – When first delivered, allow a few hours of air-out time before use.

In Summary

Body impressions are a normal and healthy sign that your mattress is adapting to your body and providing the comfort and support you need. With a little regular care, your mattress will stay comfortable and supportive for many years.
