I have a Leesa and don't love it, but I've had it over a year now, so can't return it. I didn't realize "mom-n-pop mattress stores" existed -- how would one find one? I ended up with an online-mattress purchase because of a poor experience with both a Mattress Firm store (pushy salespeople) and most obnoxiously with a specific manufacturer, Simmons. I stayed at an AirBnB in SF years ago and the bed was noticeably the most comfortable bed I've ever slept on. I messaged the host _years_ later and asked him what type of bed it was, and to my surprise and delight, he messaged me back with text and images of the tags on the mattress. When I tried contacting Simmons by phone, email, and even Facebook Message, telling them I would BUY that mattress, no matter the cost, if they could point me in the right direction, I got nowhere and was made to feel like I was a bother. So while it's easy for me to believe that these online mattress companies are marketing companies glueing foam together, maybe this is what we needed to make an outdated industry improve.
