Ok people, I'm 22 years old. I've slept in three beds in my entire life. Obviously started out in a crib, moved to a twin and slept on that same mattress until about 19. Moved in with my fiance and sleeping in a king mattress until May 11th 2020 when our Split King Pro-Adapt mattresses finally arrived! We both got to the point where we were having a lot of problems in our old mattress. He has sciatic nerve issues occasionally and is always tossing and turning. I am a very light sleeper and was barely sleeping the last 3 weeks before our new mattress was delivered. The nerves in my lower legs also seem to go crazy when I am laying down so any type of movement from my fiance makes it that much more stressful especially when he thinks he has to launch hmself in and out of bed in the middle of the night lol. It was miserable! We decided to get a firm split king because of our different needs though we both wanted a firm mattress and I had read previous reviews where some people no longer felt their partner move around so that really made me want a split king. We decided to pair it with the Ergo adjustable base (Separate review.. life changing) and it took over a month to get everything delivered but finally low and behold we are sleeping better! Love me a firm mattress! Our old one just felt too soft and I couldn't seem to find a position where my body truley felt relaxed. I barely feel him moving around and the nerves in my legs have calmed down so much I would assume due to now I sleep wih the bottom end of the mattress lifted (Thanks Ergo base)! I have been sleeping better though still having some issues on night where I just can't sleep. I am getting ready to buy some new pillows from here that I think will work with the mattress and base and completely fix all of my problems! If you get a firm, once you set it up, it will feel really hard but don't be alarmed! That will change when it warms up to the temp of the room. When we set it up and sat on it, we looked at each other like uhhhhhhh this is like laying on cement and we were hoping we didn't just make a giant mistake lol but nope it was perfect once it warmed up! Only thing that kind of sucks is that I read you shouldn't use heated blankets on the mattress. I have been using a heated blanket the passed 2 years since my feet can't ever get warm. They are always freezing cold at night and would cramp up in the middle of the night so I'm having a lot more cramping now but it's a small price to pay. I think I just need a better comforter. Overall, I love this mattress and am trying to convince my parents they should get one too! Was well worth the money! You spend a big portion of your life in bed. Might as well be comfy! All of my future bed products will now be purchased through Tempur-Pedic!
