Your First 100 Nights.
A new mattress takes time, like a new pair of shoes. Here is what to expect, and two simple habits that help it break in evenly.
Four Things to Know.
Showroom beds have had lots of guests on them, so they feel softer. Yours is brand new.
About 3 weeks to get used to it, and about 90 nights to fully settle in.
After years on a worn-down bed, real support can feel firm at first. That is normal. Give your body a few weeks.
Use a solid platform, bunkie board or matching foundation, with slats no more than 2 inches apart. An old box spring can feel like a dip. Warranty details.
Firm at First? That's Normal.

Turn It Head to Foot.
You sleep in the same spot every night. Turning it lets the whole bed break in, not just your spot.
Turn it, don't flip it. Two people, about a minute.Only flip it if your mattress is made to be flipped. Most are built one-sided.

Use the Middle Too.

Easiest fix: sleep in the middle.A few nights a week for the first 90 nights. Movie night, lazy Sunday, kids piling in.

Optional: a quarter turn.Turn your king 90° for a night or two, so you both sleep across the old middle. It hangs over the base a little, so turn it back after.Bed frame or suite with side rails? Skip this. Sleeping in the middle does the job.

Good Questions.
Is a new mattress supposed to feel firm?
Yes. Showroom mattresses have had lots of guests lie on them, so they generally feel softer than a brand new one. Your body is also used to your old bed, so real support can feel firm at first. The comfort layers relax over the first few weeks.
How long does it take to break in?
About 3 weeks to get used to it and about 90 nights to fully settle in. Turning it head to foot every 2 weeks helps it break in evenly.
Should I flip my mattress?
No, unless your mattress is made to be flipped. Most mattresses today are built one-sided. Turn it 180°, head to foot, instead.
How often should I rotate it?
Every 2 weeks for the first 90 days, then every 2 to 3 months. It takes two people and about a minute.
Why does my king have a hump in the middle?
Two people sleep on their own sides, so the sides break in while the middle barely gets used and stays firmer. It can happen on any king. For the first 90 days, sleep through the middle a few nights a week and turn it every 2 weeks so the whole bed breaks in evenly. A quarter turn for a night or two also helps: you sleep right across the old middle. It hangs over the sides of the base a little, so turn it back after. Skip it if your bed frame or bedroom suite has side rails.
Does my bed base matter?
Yes. Your mattress needs solid support: a platform, bunkie board or matching foundation with a centre support, and slats no more than 2 inches apart. An old box spring or wide slats can feel like a dip that no turning will fix.
What if it still doesn't feel right?
Give it at least 21 nights first, since your body is adjusting too. If it still is not right, talk to the store you bought from. Our Returns & Exchanges page explains your options.
