The lowest additional riser. It is a starter riser.
As an add-on for family members who are not as flexible as those who use medium or tall risers. Great to maintain spinal flexibility following a spinal injury or recent spinal surgery.
Excellent for those who are challenged by the medium risers but want the option to switch risers to fit their fluctuating spinal flexibility.
The low riser works fine, but the pegs are extremely tight such that I had to use a hammer to install them. I also had to use a hammer to remove the 2 inch risers.
I am female, 6'3", late 50's and terrible posture. Trying to correct it. Felt because of my terrible posture the 2 in riser was too high. Got the 1.5 and a much better fit for me. I can't wait to move back up to the 2 in - but my back feels amazingly better after using the board and it definitely helping me to correct many years of neglect to my back. I do expect to be on the 1.5 riser for a good while, bad posture not corrected overnight!
