People with spondylitis are encouraged to sleep on a firm mattress with the back straight. Placing large pillows under the head is discouraged, since it may promote neck fusion in the flexed position. Similarly, propping the legs up on pillows should be avoided because it may lead to hip or knee fusion in the bent position. Choose chairs, tables, and other work surfaces that will help avoid slumping or stooping. Armchairs are preferred over chairs without arms.
Since those with ankylosing spondylitis could easily hurt their rigid necks or backs, special care should be taken to avoid sudden impact, such as jumping or falling.
