Usually bed in a box mattresses don't work for me, and I can tell when a hotel or airbnb uses one. They hurt my hips, and my shoulders (wide shoulders), without fail. I saw an ad for the geli bed and figured with the 100-night trial I would just return if it didn't work out, nothing to lose. Best mattress I've ever used. Easily, the support is strong yet somehow my hips and shoulders experience ZERO pain and this is from night one to night 12. Incredible. I'd strongly recommend a Geli Bed if you've got hip or shoulder pain like me, being a side sleeper. A+
