We purchased the Aireloom Emerald Queen bed set in 2012. Although it cost more than double what we intended to spend on a mattress set, we were reassured by the 20-year warranty backed up by the company. The bed afterall looks plush and is very comfortable when it first comes out of the plastic. After the first 5 years of use, and many rotations, the bed has a sag. We are not of unusual size or weight, and we don't jump up and down on the bed. So this was not expected. We have contacted the company twice in the last 10 months complaining about the mattress performance. Each time, they sent an inspector, who conducts various measurements on the mattress. And, each time, the determination was that the mattress did not have enough sag for the warranty to go into effect. THE ISSUE IS THAT NO MEASUREMENTS ARE TAKEN WITH ANY IMPRESSIONS OR WEIGHT BEARING ON THE BED. No matter how unsaggy a bed looks when you're not laying on it, it's worth nothing if it sags with weight placed on the mattress. In order to cash in on their "warranty", you have to sleep on a SAGGY MATTRESS for years, until it sags so much that their NO PRESSURE/NO WEIGHT measurements reflect any kind of sag. You think you're getting a high-end product that will last you 10 or 15 years, but it's worth less than a cheap mattress after a few years. We are very disappointed in the deceptive 20 year warranty.
