Happiness Guarantee


We’re so confident we’ll match you with the right mattress, you can take it home and sleep on it for 120 nights. If it’s not the perfect fit, we’ll happily pick it up and pair you with a new one.


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.

120 NIGHT SLEEP TRIAL– It will take time for your body to adjust to your new mattress, so you should sleep on it for a minimum of 30 nights to allow for this adjustment period. If you are not comfortable within 120 nights of the original mattress delivery date, we will do our best to match you to the right mattress. Subject to the above restrictions, our 120 Night Sleep Trial is valid for one return and/or one exchange per purchase, which must be done within 120 days of the delivery date of your original mattress. You may exchange your mattress once, with a redelivery fee of $79.99 ($99.99 in select markets). If you still aren’t satisfied with your new mattress, you can return it with a return delivery fee of $79.99 ($99.99 in select markets) plus a restocking fee equal to 10% of your original mattress purchase price (not to exceed $250). Restocking fee not applicable in Hawaii. Restocking and redelivery fee not applicable to tulo and Purple. Mattress Firm is unable to exchange or refund stained, unsanitary or damaged mattresses under the 120 Night Sleep Trial. Mattress Firm highly recommends using a waterproof mattress protector to help keep your new mattress clean. In addition, we recommend keeping all original tags on your mattress. Do not remove the law tag from the mattress or foundation, as it will void the 120 Night Sleep Trial. Please note that our 120 Night Sleep Trial is not valid on warranty exchanges, clearance merchandise, floor models, pillows, mattress protectors, adjustable bases, furniture or other accessories.
