Standard shipping is curbside: it ships by freight to the 48 contiguous states, and the freight company delivers to a carport or first-floor entryway. From there, plan on two or more people to move the box inside, and measure every doorway, hallway turn and stair landing on the way to the room, not just the room itself. Assembly is required and can take 30 to 90 minutes, depending on the chair. Many product pages also list In-Home Delivery (inside your home, no stairs, just inside the doorway) and In-Home Delivery and Assembly; check the product page for the options and cost for your model. Once it's in place, leave the listed wall gap so the backrest can recline fully and leave room in front for the leg rest to extend. Check the owner's manual for power and outlet guidance before you plug it in. Try several programs in the first days so you can raise any fit questions early. If you return a chair, a return fee applies.
Ownership: warranty and care
- Osaki Grand Duo 4D+4D: the listed warranty is 3 year Limited Warranty; the upholstery is synthetic leather; the back pad is removable; the owner's manual can be downloaded from the product page.
Read the warranty terms on the product page so you know what's covered and for how long. Keep the chair out of direct sun and away from heaters to protect the upholstery, and clean it the way the manual describes. If a pad is removable, take it off now and then to check for wear. Keep the remote and any power cords where they won't be stepped on or pinched by the recline.
Honest trade-offs
The Grand Duo packs the most programs and airbags of the Osaki Duo flagships into a chair that sits 1" from the wall. It's big and heavy, and its weight rating is 280 lbs. If you want live body scanning and a 5D upper mechanism, compare the Apex Duo for $1,000 more.
