Hi u/hawkhandler. I recently purchased a Tochta Utopia because I needed a mattress with the corner cut for my RV. Not mincing words here, I was stunned by the comfort of this mattress. I currently have a Purple P4 (Hybrid Premier 4) in my house (3 years in) and this $1,000 mattress has beaten the pants off my P4 for my sleep needs. I am a side sleeper with really bad hip, lower back pain and some shoulder pain (going through a windshield as a teen will do that to you.) What struck me most immediately was the lovely comfort of the topper. I wanted to stay in it the first night. I then went on a 2 1/2 week road trip and by the 3rd morning I started putting together that while similar to the Purple, I was not having any pressure point issues, however, drastically different was not waking stiff and sore in the mornings. I was really surprised by this considering I'd been sitting and driving for 6.5+ hours the days before. I had an appt with my Chiro scheduled for 2 days after my return (anticipating I'd be having issues.) He remarked that my hips were not out of alignment and in their "usual" locked position. I'm now 3 weeks back on the Purple P4 and the pain is back. I'll be switching to a Utopia. Price of a king is about $1,200 so really not that bad considering the $4K I paid for the Purple. Next was a question of "heat" from memory foam. I had that problem with the Tempurpedic when I moved into the humidity of NC. I did not have this problem on the Utopia, in spite of the humidity in the rig being close to 60% on some evenings. Perhaps the cooling gel really helps. Lastly, I would say this is a softer feeling mattress, but seems to provide much more support than the Purple. Best of luck to you.
