What are the height ranges when the Smart-Rail is open from the bed?
When in the open position, the rail has a height range of 27.25"/699mm to 36.25"/921mm. This allows you to set the height to what is most comfortable setting.
Can I put a Smart Rail on each side on my bed?
Yes, you can (as long as your bed is big enough to place both support rails between the box spring & mattress without overlapping).
