Body impressions up to 1.5” are considered normal and desirable in luxury mattresses. Our mattresses are designed to conform to your body over time while still delivering correct postural support. To quote the Better Sleep Council on body impressions:  “Many of today’s top-quality mattresses use extra-plush foams and fibers to create comfort layers designed to cradle your body and relieve pressure. In the first few weeks you sleep on a new mattress with extra comfort layers, you will likely notice some body impressions on the surface. These impressions are normal. They indicate that the comfort layers are conforming to your body as they are supposed to do, and shouldn’t be considered a sign that something is wrong with your new mattress.” Please refer to your Mattress Care and Warranty booklet for any rotation instructions that may apply to your Kingsdown mattress.
