  • ObusForme Wideback is 3" wider and 1" taller than the ObusForme LowBack model. Designed for broad backs and builds. Fits most males Size 44+ and females Size 18+.
  • Obus Backrests add several inches of thickness behind you, so you will sit closer to the front edge of your seat and closer to the steering wheel when driving - an advantage if you have short legs.
  • Fits folks with mild/flat lumbar curvature without the pad. Fits folks with deep lumbar curvature with the pad. Does not fit folks with an average depth lumbar curve.

Positioning the lumbar pad

  • There are no hard and fast rules about positioning an ObusForme Lumbar Pad. Some people even put the lumbar pad behind the backrest to change its recline angle.
  • Important! Velcro pad attachment can wear out the cover fabric. We recommend you insert it within its plastic wrapper INSIDE the cover. Works great, looks better, you won't loose it, and you'll preserve your cover fabric.
