What is the 120 night sleep trial?

Diamond offers a 120-night trial period that starts once your Diamond mattress is delivered to your door. That said, not many Diamond users return their mattress, which makes us pretty confident that you’ll love yours too. But give one of our mattress a try and see for yourself. 

We make it easy for you to ease into your new Diamond mattress. Every body is unique and needs time to adapt to a brand-new surface, which is why we give you 120 nights to sleep on it. If it’s not a perfect fit, we’ll happily pick it up and pair you with a new mattress.

1. Mattress Removal

We’ll work with you to schedule a convenient time to pack up and remove the mattress, at no extra fee.

2. Recycling or Donation

Nothing we take back goes to waste. We recycle every returned product or donate it to a charity.

3. Your Money Back 

You will receive a full refund of your original form of payment.

Qualifying Mattresses: 120 Night Trial applies to the Diamond Grateful, Intention, Faith, Transformation & Rally 2 mattresses. Legacy mattress models not listed on this website do not qualify. The sleep trial is limited to one (1) comfort exchange per customer.
