Sometimes a sofa is uncomfortable because too low. And especially at a certain age, and especially with people, operated on hips or knees, and we see people use only chairs, which is a shame.
All you have to do is build a small wooden or plywood platform, pushing the edges a little so that the feet of the sofa can not jump.
By raising it a little below the height of a chair, it will find a lot of appeal, and it will be used instead of cluttering for nothing.
One could also make two small stable pedestals, for the feet on each side so one on the right, one on the left.Suggest a tip for this theme
