This Mattress is listed as [Krisha] by Alwyn Home. It is actually a SSecretland product,  which caused me confusion. After unboxing and unwrapping,  it was amazing to watch it become a 12 inch Mattress within minutes, and almost no odor! We put it into use on the third day. The writeup claimed good edge support,  NOPE! Not very plush either, but surprisingly,  comfortable enough for this side sleeper who has endured lots of shoulder pain over the years, so it passes my most urgent requirements. Enough back support, enough cushion, enough give to relax into when laying on my side so that my back, hips and shoulders are properly aligned. A keeper in all but one aspect,  edge support,  which should not have been mentioned in the writeup, since it is not really good for that at all. But this Mattress has its real positives, and a keeper!
