This is two measurements, and it is the choice worth taking time over.

Width is how wide the seat is across. Sit upright, have someone measure the widest part of your hips, then add about two inches so you are not pressed against the armrests. Round up to the nearest size below.

Depth is how far the seat runs from your back to its front edge. 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 your knee. A seat that is too deep presses behind the knee and pushes you into a slouch.

All three sizes cost the same.

One thing to get right on this chair. The 18" and 20" seats can be set to 18" deep, and at that setting the chair is rated to 400 lbs. rather than 450 lbs. The 22" seat only goes down to 20" deep, so it holds the full 450 lbs. If you need the full capacity, take the 22" seat or set a narrower one no shallower than 20".

The seat folds flat and comes with a lap belt, 60" on the two narrower seats and 70" on the 22" seat.

If a therapist has measured you, their numbers win over anything here. If nobody has, use the measuring guide on this page.

This section sets which armrest the controller sits on.

Put it on the hand you already use. For most people that is the hand they write with. Choose the other side if that hand is out of commission.

The included mount on this chair is a fixed in-line bracket. A swing-away mount swings the controller out to the side, so you can pull all the way up to a dining table, a desk or a work counter without the control box hitting the edge. Raising the armrest does not do the same job, because the chair is harder to control with the armrest up.

The swing-away also moves the controller out of the way when you get in and out. The joystick is a delicate part, and people grab it to push themselves up, which is how it gets broken.

Pick the side after you have picked the hand.

This is the armrest the joystick sits on. Most people choose the side of their stronger hand. Both sides cost the same.

This section is what your feet rest on.

The standard footrest is an angle adjustable platform that flips up out of your way when you get in and out. It suits you if you transfer sideways or stay seated once you are in the chair.

Swing-away legrests move to the side and lift off. Choose them if you need to get close to a bed to transfer across, or to stand up out of the front of the chair. The two footplate sizes are about shoe size, so take the larger one if you wear a big boot. On this chair they also adjust from 60 to 90 degrees in five degree steps.

Elevating legrests do everything the swing-away pair does and also raise each leg on its own, on a padded calf support. Choose them if you have swelling in your lower legs, or if you have been told to keep a leg raised.

These are extras that fit onto the power wheelchair, and every one of them is optional. Adding them here means they arrive with it rather than as a separate order later.

Read each card before you add two of them. Some accessories mount in the same place, so only one of those can be fitted at a time.

This section is how your order reaches you and how far into your home it comes.

Curbside is the free option. The power wheelchair ships from the manufacturer straight to your address. Allow about two to three days for the order to be processed and shipped, then about five more in transit depending on where you live. No carrier in this trade quotes an exact date, so treat both figures as estimates rather than promises. It is left boxed at the curb, and everything after that is yours.

Read this before you take the free option. A full-size power wheelchair is a two person job. It usually arrives in more than one box, and those boxes usually will not fit through a standard 32 inch doorway, so they have to be opened in the garage or outside and the power wheelchair driven in once it is built. The setup is the hard part. It is not beyond anyone, and it is far easier the second time than the first.

If you have not done one before, take an upgrade.

Inside delivery means we bring it just inside your front door or into the garage, still in its packaging. It saves you the carry and leaves you the setup.

White glove takes a different route. It does not come to your address first. It ships to the delivery technician nearest you, and once it arrives there the technician calls you and books a time that suits you, then brings it into your home, sets it up in the room you choose, checks it for shipping damage and takes all the packaging away. That extra leg adds a few days, and the date is settled between you and the technician, so we cannot give you one up front.

Most people buying a full-size power wheelchair take white glove, and on this one we think that is the right call.

This section covers what the manufacturer warrants and for how long.

There is nothing to buy here. The full terms are in the Warranty tab further up this page.
