Can I use a back stretcher at my desk?

Some models (like the Everlasting Comfort board) ship with a chair strap so they can double as lumbar support during the workday, while wheel-style rollers and inversion tables are floor-only and require dedicated time. For pure office use, look for a flat or curved board with a strap; for a fuller decompression session, plan to use a wheel or inversion table on a mat.
