I first tried this mattress at a recent Air BnB. As a travelling construction worker with sleep and back issues, I get to try a variety of mattresses. Most of them are very plush, and at first I thought that was best. They feel great at first. But I'm nearing retirement age, and now I've got issues where my arms go numb at night unless I sleep at the corner of the mattress with my hands on the floor, which also helps with my developing sleep apnea.\n\nUntil I moved again and slept on this mattress. The landlord was very proud of it because it used to be his, and he selected it for his back issues. The very top is soft, but after that it's snug and firm all the way down. I'm not gonna lie, I felt like I was a little sore from it for the first 2 weeks and even told him so. But months later, someone mentioned sleep issues in a conversation, and I mentioned that mine had gone away... Wait. What??\n\nWhen I got home I found the ID tag on the mattress and took a picture of it!! My sleep issues had gone away!? I just took it for granted, but I knew that I'd be moving to a different city soon for another job, and I needed to ID this mattress. Just in case...\n\nAnother city now. Another plush mattress, and my sleep issues returned with a vengeance. I took to sleeping on the floor, which helped, and which was silly. I pulled the trigger and bought this mattress, making apologies to my new landlord.\n\nIt arrived in a smallish box, and I didn't believe a firm mattress like this could get that squished. I was very worried about that. Had I gotten the wrong one? I just wanted to get some sleep!\n\nBut no. This is the one I wanted. This is the make and model I was looking for. I opened the box, carefully cut the plastic, and it eventually poofed up. There was no wait time indicated, like with some memory foam products. I slept on it that night. It fits in my truck. It's coming with me next time.\n\n 'Nuff said.
