I just moved into an RV and was looking for a mattress for the platform in the bedroom but it’s a special size so there weren’t a ton of options so I very carefully read reviews, looked at stars of different things, and read the description. Despite slim pickings’, I still needed a firmer mattress due to a severe back injury I’ve had and in the very description it speaks of being pain relieving, to which I was a bit skeptical but everything else looked really good so I went ahead and took a chance on it. Boy am I glad I did! It only took about 2 days to decompress fully from the box. It’s quite firm yet soft enough to sink in just a little, like the perfect amount. Now let me touch on this cooling effect and pain relieving factors. WOW! I mean WOW! I have been sleeping beautifully for days now, sleeping without waking up in the middle of the night due to back pain from laying down that long and I normally wake up for the day in a world of pain and have to take my pain meds before I can even sit up and stand up (successfully). I have not woken up with an ounce of pain, I wake up refreshed and ready for the day. This morning I didn’t even have to start the schedule of my 4 times a day medication upon opening my eyes during normal life with my normal what I thought was a great bed, a Serta. The cooling feature is just as wonderful. It feels great, I haven’t gotten the least bit warm as I usually do. So the description of the mattress is spot on, believe every word of it and what a bargain price for all of that!! When it comes time to replace it in my stationary, lived in full time RV, I will never get any other mattress. This mattress literally has everything I’ve ever wanted in a mattress and for such a great price at that. Needless to say, there are no cons whatsoever.
