1 this Massage Chair has SL track; S track is the roller track that does the deeper massage on neck and lower back. L track is the extended version of the S track but with the straight track from head to lower back. SL track has the curved deep massage on neck and lower back, massage from head all the way to the buttock.
2, when the massage chair get started, the leg part got raised up so your body is in a very relaxed position to get a fully massage , (especially with the SL track, for people who sit every day this really helps)
3, Easy to use, remote control is simple，from relax to strong mode, you can choose to heat the lower back. It has rollers to massage the bottom of your feet. it has Tai Stretch function, for people who love to stretch.
4 Save the room, when the massage chair get started, it slides down (not lie down), the back of the chair only goes back about 2 inches, means you can have this massage chair in a smaller room like bedroom or office.
With all this advanced functions and fraction of the price of the brand name massage chairs, I really recommend this massage chair to anyone who is looking for good quality massage chair.
