I believe it’s their original one, flatter looking one. I was hauling it back and forth to work since I sleep at work (firefighter). Ended up buying one for work. They have little inserts you can throw in if you feel it’s too low

Side sleeper here. Get the purple mattress and pillow. Had mine for three years, love it. the downside is I now hate memory foam mattress toppers. They’re just terrible in comparison. Good luck
