The NXT Xtend is a height adjustable thoracic back support for manual and power wheelchairs. The shell adjusts from 16" to 20" tall, in 16" to 24" widths, with a 3.5" contour or the DEEP 5.5" to 7" contour.
NXT's Xtend has a two-piece aluminum shell. The lower section holds the pelvis and the upper section slides from 16" to 20" tall, with the user seated.
What stands out
The Xtend is the back to look at when the right back height is hard to pin down, or when it is likely to change. The shell is two pieces of aluminum. The lower piece stays put and supports the pelvis, and the upper piece slides up or down anywhere from 16" to 20", so the lateral contour lands at the height where the trunk needs it. The change is made with the user in the chair, which lets a therapist or the user tune it by feel. The standard Xtend has a mild 3.5" contour. The DEEP version wraps further around the trunk and its laterals set from 5.5" to 7", which suits users who need more help staying centered. Pick the width of your back canes, then choose the contour. Check the weight limit for your width before you order, because it rises from 300 lbs. to 400 lbs. at 22" wide.
Straight talk
Is it right for you?
A good fit if you
- need a back height that can be tuned after the back is on the chair
- want thoracic lateral support at a height you set
- want laterals or a head support added to the same back later
Look elsewhere if you
- need a back shorter than 16"
- weigh more than the limit for your back width
- want to try it and send it back, because a back support is not returnable
The NXT Xtend Height Adjustable Thoracic Back Support is covered by NXT Seating's own limited warranty. The coverage we have on record is below.
The owner's manual is the full warranty
The owner's manual for this product has its own warranty section, and that section is the complete statement of what NXT Seating covers, for how long, and what falls outside the coverage. Read it before you file a claim. If anything on this page differs from the manual, go by the manual.
Owner's manualThis product cannot be returned
A back support sits against the body, so once it ships it cannot be returned. Measure your back canes before you order and use the build steps above. The warranty is unaffected, so a defect is still covered.
If something goes wrong
Call us first at 1-855-HIELINE. We file the claim with NXT Seating for you and get the covered part sorted out rather than handing you a phone number.
