Free Curbside Delivery – Avg. Shipping Time 7-10 Business Days
Curbside Delivery ships via Freight to the 48 contiguous states. The freight company will deliver your massage chair to a carport or first-floor entryway. Please check the box dimensions and ensure it will fit through your doorway. Assembly is required and can take 30-90 minutes, depending on the chair.
In-Home Delivery – Avg. Shipping Time 7-10 Business Days
In-Home Delivery ships via Freight to the 48 contiguous states. The freight company will deliver your massage chair inside your home (no stairs) just inside the doorway. Please check the box dimensions and ensure it will fit through your doorway. Assembly is required and can take 30-90 minutes, depending on the chair.
In-Home Delivery and Assembly – Avg. Shipping Time 10-20 Business Days
In-Home Delivery and Assembly is the same as White Glove Delivery. Your massage chair will be shipped via Freight to the White Glove Delivery warehouse. They will contact you to schedule a delivery time and date when they receive your order.
The White Glove Delivery team consists of a two person installation team that will deliver (up to 2 flights of stairs), unpack, and install your massage chair in your room of choice. These are not professional massage chair installation experts but a furniture installation team. They may or may not have installed your massage chair model before.
Massage chairs are heavy, so make sure you have some extra help to move the boxes and help in assembly.
Please contact us for a shipping quote if you live in Hawaii, Alaska, or Canada.

-
SL-Track
The SL-Track follows the natural curve of your spine, guiding the massage rollers from your neck and shoulders all the way to your hamstrings. The track ensures continuous contact and balanced pressure throughout your entire body.
