Quick answer: The Osaki Atlas XL 4D ($5,999) and Osaki Duke XL 4D ($6,999) share the same rated fit: up to 400 lb and up to 6'8", with a 23-inch seat and a 26-inch shoulder width. Pick the Atlas XL to get that fit for $1,000 less. Pick the Duke XL if you want a heated shawl and a more compact recline.
If you're both tall and heavy (over 300 lb, up to 6'8"), the Atlas XL and Duke XL are the two chairs we sell built for that combination. Among the chairs we sell, they're the only two rated for 400 lb, and the only two that list both a 23-inch seat and a 26-inch shoulder width. This guide compares them side by side.

Where they're the same
Fit for big and tall bodies
Both chairs use a reinforced steel frame rated for users up to 400 lb and up to 6'8". The 23-inch seat and 26-inch shoulder width are the same on both, and each has a spring-loaded footrest that extends as you push with your legs. The Atlas XL's page lists up to 11 inches of extension.
Massage hardware
Both have a 4D mechanism (you can adjust speed and rhythm, not just depth), a body scan that maps your back before each session, 48 air cells across the shoulders, arms, calves and feet, foot rollers, a stretch program, zero gravity recline, a touchscreen tablet, armrest controls, Bluetooth speakers and a USB-C port.
Warranty, shipping and financing
Both carry Osaki's 3-year limited warranty: 1 year of in-home service, 2 years of parts and 3 years on the structural frame. Both ship free curbside in the contiguous U.S. (48 states), and financing is available as low as 0% APR, subject to credit approval.
Where they differ
Heat
This is the clearest difference. The Atlas XL heats the lumbar area and the feet. The Duke XL has a heated shawl that warms the front and back of the shoulders, plus foot heat. If warmth around your neck and shoulders matters to you, that's the Duke's main advantage.
Room and recline
The Duke XL is the more compact chair when reclined: 67 inches long versus 74 inches for the Atlas XL. The Atlas XL needs a little less space behind it, 12 inches versus 13. Both are 35 inches wide, so measure the length of your space as well as the wall gap.
Calves, controls and timer
The Duke XL's page lists four calf bumpers working with 14 air cells, and calf kneading. The Atlas XL's page lists air compression for the calves. The Duke's tablet offers English, Korean and Chinese, while the Atlas offers English and Chinese. The Atlas XL's timer runs 5 to 30 minutes, and the Duke XL's page lists 15 minutes.
Shorter users
The Atlas XL's range starts at 5'0", and the Duke XL's starts at 5'2". If a shorter person in your home will use the chair too, the Atlas covers a slightly wider range.
Which one should you buy?
Choose the Atlas XL if...
- You want the 400-lb, 6'8" fit at the lower price.
- Lumbar heat is enough for you.
- A shorter family member (5'0" to 5'2") will also use it.
Choose the Duke XL if...
- You want the heated shawl for your shoulders.
- You'd rather have the shorter 67-inch reclined length.
- The extra calf kneading appeals to you.
Consider something else if...
If you're under 375 lb, the Titan Grande XL ($2,499) is rated for 375 lb and 5'2" to 6'6", with a 22.5-inch seat. If you're tall but under 300 lb, chairs rated to 6'9" or 6'10" may fit you better. Compare them on our big and tall guide or browse the Big & Tall collection.
Frequently Asked Questions
Is the Atlas XL or Duke XL better for heavier users?
Neither. Both product pages list a recommended weight of 400 lb, with the same 23-inch seat and 26-inch shoulder width.
Which fits a smaller room?
The Duke XL is shorter when reclined (67 inches vs 74 inches). The Atlas XL needs slightly less wall clearance (12 inches vs 13). Both are 35 inches wide and weigh about 326 lb.
Is the Duke XL worth $1,000 more?
It is if you value the heated shawl, calf kneading and shorter recline. If those don't matter to you, the Atlas XL gives you the same rated fit for less.
Do they have the same warranty?
Yes. Both carry Osaki's 3-year limited warranty: 1 year in-home service, 2 years parts and 3 years on the structural frame.
