How does the Sleep Number 100-night trial work?
Eligible Sleep Number mattresses include a 100-night in-home trial starting on the day the bed arrives. Sleep Number says it can take up to 30 nights for your body to adjust to a new mattress and requires you to sleep on the mattress for a full 30 nights before arranging a return.
If you remain dissatisfied after that adjustment period, contact Sleep Number before the end of the 100-night trial to request a return authorization.
Can you return a Sleep Number mattress?
Yes, if the mattress is eligible and you are still within the 100-night trial. The return must be authorized by Sleep Number first. The company specifically warns that an item returned without prior approval can be discarded with no refund or credit.
Who pays return shipping?
Sleep Number’s published trial terms place return-shipping and incidental return costs on the customer. Original shipping or home-delivery-and-setup charges are also generally not refunded.
This can make the practical cost of a Sleep Number return meaningfully higher than mattress trials that include free pickup.
Can you exchange a Sleep Number mattress?
Yes. Sleep Number allows a one-time exchange during the 100-night in-home trial. But the replacement product does not receive another 100-night trial. Sleep Number says the exchanged product is considered final sale and cannot later be returned or exchanged.
Can you return a Sleep Number adjustable base?
No. Sleep Number’s current exclusions list adjustable bases and FlexFit smart adjustable bases as final-sale products. That includes FlexFit models sold as part of certain mattress packages.
This is one of the most important details to understand before buying a complete Sleep Number setup: the mattress may have a 100-night trial while the adjustable base does not.
How do you return a Sleep Number mattress?
- Keep the bed for the required 30-night adjustment period.
- Make sure you are still within 100 nights of delivery.
- Call Sleep Number customer service to request return authorization.
- Follow the packing, pickup, or shipping instructions Sleep Number gives you.
- Keep your authorization information and shipping documentation until the refund is complete.
How long does a Sleep Number refund take?
Sleep Number currently says refunds are generally processed back to the original payment method within about 21 days, subject to applicable law. If the original payment method is unavailable, the company may issue the refund by check.
Do you have to ship the mattress yourself?
Return logistics depend on the product and the return method authorized by Sleep Number. The company publishes package-size and weight limits for shipped returns, including a maximum of 150 pounds per package and dimensional limits for parcel shipments.
For some mattress returns, Sleep Number may arrange a pickup process. Follow the return instructions tied to your authorization rather than shipping a mattress on your own.
What items are final sale?
Sleep Number’s current exclusions include adjustable bases, FlexFit smart adjustable bases, upholstered furniture and upholstered-furniture accessories, and display products. Product-specific exclusions can change, so verify the terms shown on your order before buying.

How Sleep Number compares with other return policies
Sleep Number’s 100-night mattress trial is competitive on length, but the 30-night minimum, customer-paid return shipping, and final-sale adjustable bases are important tradeoffs. Compare it with our mattress return policies comparison, Tempur-Pedic return policy, Purple return policy, and Saatva return policy.
Bottom line
Sleep Number gives eligible mattresses a 100-night in-home trial, but you need to sleep on the bed for 30 nights before requesting a return. Returns require authorization, return shipping is your responsibility, and adjustable bases are final sale.
