It carries up to 600 lbs., on four seat posts
A rear-wheel drive power chair for riders up to 600 lbs., with a 24" or 26" seat in captain or pan style and a 24" backrest. Batteries and charger included.
Built for real life
What stands out
Carries up to 600 lbs.
The seat sits on four posts rather than one, which is what holds a wide seat steady at this weight, and the backrest is 24" high.
24" or 26" seat, captain or pan
Four seat configurations. The 24" seat is the standard width and the 26" adds $200. The depth adjusts from 20" to 22" in 1" steps once the chair is with you.
12" pneumatic drive tires
Large air-filled drive wheels with 9" pneumatic casters and 3" of ground clearance. Air gives a softer ride than foam, and it means the tires can be punctured and need checking.
Turns inside 31.5"
Rear-wheel drive with four-post seat mounting, rated to climb 10 degrees. That is a wide turn, so measure the tightest corner in the house before you order.
Batteries and charger included
Two 12V Group 24 AGM batteries at 75 Ah and a 6A off-board charger come with every chair, and they carry it up to 32 miles on a charge.
It comes apart
The chair separates for transport. Be clear about what that means at this size: the heaviest single piece is 167 lbs., so it is a lift for two strong people or a vehicle lift.
The Atlantis is a bariatric chair and it should be judged as one. The number that matters is the four seat posts: at 600 lbs. a single-post seat flexes, and the four-post frame is the reason this chair holds a 26" seat steady where a converted standard chair would not. The rest follows from that. The backrest is 24" high rather than the 21" you get on a full-size chair, the motors are 300W, and two Group 24 batteries at 75 Ah are included and carry it up to 32 miles, which is the longest range of any Merits power chair we sell. The 24" seat is the standard width and the 26" adds $200, so size the seat to the rider rather than defaulting to the wider one. What you trade for all this is space and upkeep. The chair is 44" long and needs 31.5" to turn, so the deciding measurement is not your doorway, it is the corner where a hallway meets a bathroom. The tires are pneumatic rather than foam-filled, which rides better and can go flat, so somebody has to check the pressure. And it weighs 304 lbs. with a heaviest piece of 167 lbs., so moving it between floors or into a vehicle is a real job rather than an afternoon one. If you are close to the top of a 450 lbs. chair rather than past it, look at the Vision Super first, because it is a smaller machine to live with.
Straight talk
Is it right for you?
A good fit if you
- weigh up to 600 lbs. and need a chair rated for it
- need a 24" or 26" seat in captain or pan style
- want a 24" backrest and a padded captain seat for a long day in the chair
- cover distance outdoors, this chair runs up to 32 miles on a charge
- want a softer ride, the air-filled tires absorb more than foam does
Look elsewhere if you
- have tight doorways or hallway corners, this chair is 44" long and needs 31.5" to turn
- do not want to maintain tires, the pneumatic wheels can be punctured and need checking
- need to load it in and out of a car often, the heaviest piece is 167 lbs.
- want to go faster than 5 mph
- want a color beyond Candy Apple Red and Metallic Blue

Common questions
32" with the 24" seat, the figure on Merits Health's Atlantis flyer. One other Merits document prints 27", which is narrower than the 26" seat plus its armrests and drive wheels could ever measure, so we publish 32". Merits print no separate overall width for the 26" seat, which sits on the same base.
A Dynamic LiNX. Merits Health's price list, their March 2026 order form for this model (P710) and the flyer all name the LiNX, and the order form sells its swing-away bracket as the bracket for LiNX. The March 2026 manual that names a P&G VR2 is filed as the P710A's, a second configuration of the Atlantis.
Yes. Two 12V Group 24 AGM batteries at 75 Ah and a 6A off-board charger come with every chair. They carry it up to 32 miles on a charge, which is the longest range of any Merits Health power chair we sell.
Yes, $200. The 24" seat is the standard width on this chair and the 26" is an upgrade, in captain or pan style either way. The depth adjusts from 20" to 22" in 1" steps on all four. Size the seat to the rider rather than taking the wider one as a matter of course, because a seat that is too wide leaves nothing to brace against and pushes the joystick further from your hand.
Sit upright, have someone measure the widest part of your hips, then add about two inches and round up to 24" or 26". The captain seat is the padded high-back seat with a headrest and it is what most people order. The pan seat is a flat base for your own pressure cushion, and it is the one to pick if a therapist has specified a cushion. If a therapist has measured you, their numbers win over anything here.
They can. The 12" drive wheels and the 9" casters are pneumatic, which means air-filled, so they ride softer than the foam-filled tires on our other Merits Health chairs and they can be punctured. Somebody needs to check the pressure from time to time, the same way you would on a bicycle.
The chair comes apart, but be realistic about the size. It weighs 304 lbs. set up and the heaviest single piece is 167 lbs. That is a lift for two strong people or a vehicle lift, not something to plan on doing alone.
The chair is 44" long, 50" high and needs 31.5" to turn. The tightest spot in most homes is not the doorway itself, it is the corner where a hallway meets a bathroom or a bedroom, because the chair has to swing through it. Measure that corner against the chair's 32" overall width.
Candy Apple Red and Metallic Blue, at the same price. The color is the body shroud. Merits Health photographed this chair again in 2025 in red only, so the blue picture in the gallery is from their earlier session and shows a gray seat instead of the black one the chair ships with today.
Yes. We offer CareCredit financing with plans from 6 to 60 months. Use the payment estimate near the price to see monthly options and prequalify with a soft credit check that does not affect your score.

Select one.What does this mean?
The color on this chair is the body shroud under the seat. The seat, the armrests and the frame are the same whichever one you pick, and both cost the same.
Red is a candy apple red and Blue is a metallic blue. The chips beside each name are sampled from the manufacturer's own photographs.
One thing worth knowing about the pictures. Merits Health photographed this chair again in 2025 in red only, so the blue shot in the gallery comes from their earlier session and shows a gray seat. The chair itself ships in either color with the black seat you see on the red photographs.
Select one.What does this mean?
Two decisions here, and the width is the one that changes the price.
Width. Sit upright, have someone measure the widest part of your hips, then add about two inches and round up. The 24" seat is the standard width on this chair and the 26" adds $200. Size it to the rider rather than taking the wider one as a matter of course, because a seat that is too wide leaves nothing to brace against and pushes the joystick further from your hand.
Type. The captain seat is the padded high-back seat with a headrest, on four posts, and it is what most people order. The pan seat is a flat base you put your own cushion on, and it is the one to pick if a therapist has specified a pressure cushion. Both styles cost the same in either width.
Depth adjusts on the chair in 1" steps from 20" to 22" once it is with you. Measure from your back to the back of your knee, take off an inch or two, and aim for a gap of three or four fingers behind the knee.
If a therapist has measured you, their numbers win over anything here. If nobody has, use the measuring guide on this page.
Select one.What does this mean?
This sets how the joystick is held, and it is separate from which side it sits on. You choose the side in the Joystick position step, at no charge.
In-line is the standard mount and the joystick stays fixed at the end of the armrest.
Swing-away lets you push the joystick clear so the chair pulls under a table, a desk or a kitchen counter.
Retract4 swing-away does the same and also pulls back further, on a heavier bracket. Pick it if you eat and work at a table in this chair every day.
Select one.What does this mean?
This is the armrest the joystick sits on. Most people choose the side of their stronger hand. Both sides cost the same.
Select one.What does this mean?
The XL footplate comes with the chair. It is one large platform, 16" X 12", and it flips up out of the way.
Elevating legrests swing away to the side and raise, so a leg can be held out straight and supported. Pick these if you have swelling that is helped by raising the leg, or a knee or a hip that does not bend far. They add length to the front of a chair that is already 44" long, which is worth knowing if the turn into a bathroom is tight.
Merits Health is short of the elevating legrests on the 26" seat at the moment. We will still take the order and we will tell you what the timing looks like before you commit.
Included.What does this mean?
Curbside delivery is free on this chair. The carrier calls you to arrange a window and brings it to your curb, driveway or garage entrance on a lift gate truck.
Included.What does this mean?
The warranty is included and there is nothing to add. Five years on the base frame and 13 months on everything else, from the date you buy it. The full list of what is covered and what counts as a wear item is in the Warranty tab further down this page.
