Hi, Gary. While we don't have a 90 day guarantee or advertise one, we do have a 100 night in home trial on all of our core model mattresses. The in home trial will begin the day your new mattress arrives and will give you the chance to make sure you are 100% comfortable. If you aren't satisfied for any reason, simply give us a call for a full refund of your mattress, less the price of shipping and handling.We want all of our customers to know that our adjustable base models are all final sales, which is an industry standard practice due to their significant size and weight, which makes them difficult to ship back to our returns warehouse. We provide this information on our website, at the register in each of our stores, and on the receipt we ask you to review and sign once you complete your order, confirming that you've read and understood all of the terms and conditions.One of the reasons we make certain to provide and post the information about final sales is because we can't say for certain what may or may not have been stated at the time of purchase. This is why we ask our owners to sign their receipts confirming that they have read and understood all of the terms and conditions.We also want our customers to know that the adjustable base is made to industry standard size, which means that you'll be able to continue to enjoy the features and benefits that initially interested you in it with your next adjustable mattress in the matching size. If you have any questions we can help with or for help to get more comfortable, please give us a call at 1-888-411-2270 from 8AM-8PM CST M-F.
