You're well aware of the quality of our mattresses that lead to your purchase. In fact, we're confident you bought from the finest mattress showroom in OKLAHOMA. We also realize that the 10 minutes you spend on a mattress in our showroom is not always enough to fully evaluate how well it can improve your sleep. A new mattress is like a new pair of shoes - it takes time for the new materials to adjust to your sleeping behavior. Usually, it takes about 30 days for a mattress to start performing at its best. If after this 30 day initial "break-in" period you feel a different mattress style might work better, you can exchange your mattress up to 180 days from purchase.

180 Day Mattress Comfort Exchange

You're well aware of the quality of our mattresses that lead to your purchase. In fact, we're confident you bought from the finest mattress showroom in OKLAHOMA. We also realize that the 10 minutes you spend on a mattress in our showroom is not always enough to fully evaluate how well it can improve your sleep. A new mattress is like a new pair of shoes - it takes time for the new materials to adjust to your sleeping behavior. Usually, it takes about 30 days for a mattress to start performing at its best. If after this 30 day initial "break-in" period you feel a different mattress style might work better, you can exchange your mattress up to 180 days from purchase.

These policies constitute the MATTRESS DISCOUNTER Guarantee:

The 180 day period begins the date you receive your new sleep set. MATTRESS DISCOUNTER will allow a one-time re-selection ONLY after the 25 day adjustment or “break-in” period.

You may select a mattress of equal or greater value. If you select a sleep surface of greater value, you will be responsible for the difference in price. If a reselection is of lesser value, no refund will be made.

The original mattress purchase must also include - and you must use - a mattress protector. The mattress surrendered must be stain free.

Please take your time in your reselection choice; only ONE comfort exchange is allowed per customer.

This policy does not apply to foundations.

Re-selections are not allowed for issues regarding mattress size or height.

Bedding accessories, such as pillows, protectors, encasements, sheets, adjustable bases, or furnitures, are not eligible for returns or exchanges.

Reselections are not valid on special sizes, custom orders, floor models or warranty exchanges.

All reselections are subject to a $199 restocking fee, non-negotiable.
