The Split King with 2 Twin frames is great for partners who want different positions. The 3 motors (head, feet, lumbar) work well and provide multiple variations for sleeping and rest positions. In particular, the lumbar support helps my low back feel better. The Sleeptracker app is informative for sleep stats and the Wind Down programs are great for naps. I like the Wave Form massage feature to help me relax, but I'm not so thrilled with the SoundScape mode where it thumps with the bass beat of the music (but I may try it again anyway!). The Spotify App works will with the built in speaker, but I find my Bose headphones have higher sound quality. Overall, 10 out of 10 for meeting the advertised features.
