Happiness Guarantee

120 night sleep trial

We’re so confident we’ll match you with the right mattress, you can take it home and sleep on it for 120 nights. Love it, or get your money back.


You wouldn’t run a marathon in a brand new pair of shoes, because they’re not broken in yet. Mattresses are very similar. Your new mattress needs time to adjust to your body, so we’re giving you this trial period to make sure every night’s sleep is exactly how you dreamed it.

Here are a few key ways to break in your mattress during your 120 nights to ensure it’s perfect:

  • Let it breathe. It’s tempting to dress it up in new bedding, but give it a few hours to settle and get some oxygen flow.
  • Put on the pressure. Try walking around on it gently or using your hands and feet to apply some pressure to loosen it up.
  • Bring on the heat. This is especially important if your new mattress is memory foam. Heat helps it soften up even more.
  • Be patient. It’ll take some time for it to adjust to your body, usually around a month. Sleep on it every night so your mattress can get to know you.


Mattresses are always going on sale. Yes, we’re admitting it. So we’re making a promise to you to help you sleep easier. If a mattress you buy from us goes on sale here or elsewhere, we’ll pay you the difference for up to 120 nights.



Find your ideal mattress in just a few clicks.


120 NIGHT SLEEP TRIAL GUARANTEE – Your new mattress will take time to adjust to your body, and you should sleep on it for a minimum of 30 nights to allow for this adjustment period. However, in the event that you are not comfortable within 120 nights from your original mattress’s delivery date, we will do our best to match you to the right mattress. You may exchange or return your mattress with a redelivery fee of $79.99 in most locations*. Mattress Firm is unable to exchange or refund any mattress that is stained, made unsanitary or otherwise damaged by you under the 120 Night Sleep Trial Guarantee. Mattress Firm highly recommends using a waterproof mattress protector to help keep your new mattress sanitary. Do not remove the law tag from the mattress or foundation; removing the law tag will void the 120 Night Sleep Trial Guarantee. Subject to the above restrictions, our 120 Night Sleep Trial Guarantee is valid for up to 2 returns or exchanges per purchase, which must occur during the 120-day period from the original mattress delivery date. Please note that our 120 Night Sleep Trial Guarantee is not valid on warranty exchanges, clearance merchandise, floor models, pillows, mattress protectors, power/adjustable bases, furniture or other accessories. See a store associate or contact one of our live chat customer service representatives on our website for details.
