It can take a few weeks for your mattress to break in and for your body to adjust to the new sleeping surface. Remember, you have been sleeping on something else for years, maybe decades, so your body needs time to adjust.
Mattresses are packaged and sealed immediately after the mattress is manufactured, so when the new mattress is opened in your home there could be strong odors. These are due to the foams, glues and other materials, and are not known to be harmful, even if they can be rather annoying. These smells should dissipate in the days following. Opening windows and leaving sheets off the mattress should help air out the mattress.
Mattresses need to be supported, either by it’s matching foundation and bed frame, or a proper bed with slats. If there are questions about this, please call us, as an improper bed setup is one of the most common mistakes that are made, and can lead to mattress failure.
Minor wear, or impressions, will form as a result of the new materials settling, especially in innerspring mattresses. Minor impressions are normal. Rotating the mattress within the first two years should help the mattress wear more evenly.
