120-Night Comfort Guarantee
Quick answer: Eligible mattress purchases include up to 120 nights to adjust to the mattress. If it is still not the right fit, you may request one comfort exchange during days 101–120 after delivery. No comfort-exchange request is accepted before day 101, and the written eligibility requirements, fees and exclusions apply.
What does the 120-Night Comfort Guarantee include?
- Time to adjust to an eligible new mattress before requesting an exchange.
- One eligible mattress comfort exchange during the written request window.
- Help selecting a replacement mattress of equal or greater value.
This is a comfort-exchange program, not an unrestricted risk-free return or refund promise. Product-specific written terms supplied with your purchase control if they differ from this general policy.
Exchange window
- No comfort-exchange request is accepted before day 101 after delivery.
- An eligible request must be submitted during days 101–120 after delivery.
- The policy provides one mattress exchange.
Exchange value
The replacement mattress must be of equal or greater value. If you select a higher-priced mattress, you are responsible for the difference.
Eligibility
The original mattress must be in clean, sanitary condition and free of stains, tears, odors, abuse or other damage. Proof of purchase is required. Product-specific written terms supplied with your purchase control if they differ from this general policy.
Promotional items
If your purchase included free promotional items and you keep those items, their stated retail value will be deducted from the available exchange credit.
Items not eligible for a comfort exchange
Floor samples, closeout items, discontinued items, pillows, protectors, toppers, adjustable bases, foundations or box springs, sheets and other accessories are final sale unless otherwise stated in writing at the time of purchase.
Cancellations
Orders may be cancelled before processing begins. Once an order has entered processing, fulfillment or delivery preparation, cancellation may no longer be available.
Warranty claims are separate
A comfort preference is different from a manufacturing defect. Warranty claims are handled under the written warranty that applies to the specific mattress and are not governed by the comfort-exchange window.
How to request an exchange
Contact Texan Mattress with your original order information during the eligible request window. Our team will verify eligibility and help you choose the replacement mattress.

Quick answer
What should you know about TEMPUR-Flat® Foundation?
TEMPUR-Flat® Foundation is intended to provide a stable support surface for a compatible mattress. Before ordering, confirm the mattress size, the foundation height offered, and the mattress manufacturer’s support requirements. A foundation is not the same as an adjustable base: a standard foundation remains flat, while an adjustable base changes position. Also confirm whether your bed frame requires center support, especially for Queen, King, and California King sizes. Delivery and setup method can vary by model and destination, so use the product details and checkout information for the current order.

Questions shoppers ask about TEMPUR-Flat® Foundation
Is TEMPUR-Flat® Foundation compatible with my mattress?
Match the foundation and mattress sizes, then check the mattress manufacturer’s support and warranty requirements. Some mattresses require specific slat spacing, center support, or an approved foundation.
Is a foundation the same as an adjustable base?
No. A standard foundation creates a flat support surface. An adjustable base uses powered sections to change the head or foot position and requires a compatible mattress.
Which foundation height should I choose?
Choose a height that creates a comfortable total bed height after adding the mattress. Review the variants above and measure your frame, foundation, and mattress together.
