The NXT Optima Carbon is a thoracic back support on a one-piece carbon fiber shell, for active users who want a light chair. It comes 14" to 20" wide and 9", 13" or 16" tall.
NXT's Optima Carbon puts a gel-infused foam cushion on a one-piece T700 carbon fiber shell, with a 3" contour or a DEEP contour you set from 5.5" to 7".
What stands out
The Optima Carbon is the Optima for someone counting every pound on the chair. The shell is one piece of T700 carbon fiber, and NXT weighs the 16" by 16" back at 1.75 lbs., or 2.1 lbs. in the DEEP version. It keeps what makes the Optima work: a cut-out at the bottom so the pelvis can sit back, a low pivot point so changing the angle does not drag the pelvis with it, and a scapula cut-out that leaves the shoulders free. The lateral contours sit higher than on the aluminum Optima, which gives more support at the trunk. It comes in three low heights, 9", 13" and 16", for users who push hard and want their arms clear. The price follows the height, and the DEEP contour costs more. It is rated 300 lbs. at every width and stops at 20" wide, so a larger user should look at the aluminum Optima.
Straight talk
Is it right for you?
A good fit if you
- are an active user who wants to keep chair weight down
- want a low back that leaves the arms clear for pushing
- want laterals or a head support added to the same back later
Look elsewhere if you
- weigh more than 300 lbs.
- need a back wider than 20" or taller than 16"
- want to try it and send it back, because a back support is not returnable
The NXT Optima Carbon 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.
