If the current chair or sofa is too low, you may be able to adapt the seating so it's easier to get up from, as you can see in this photograph, depending on the person's remaining strength and balance.
To raise the seat height of a sofa or chair, try adding an extra seat cushion consider a firmer cushion for extra support. Make sure to use a no-slip liner so the cushion doesn't slip off when the person gets up. This solution works best on seating with relatively high side arms, since the addition of an extra cushion can make the side arms too low for use in pushing off to stand up.
Or, for a sofa, you may want to try placing risers under the legs. Most risers are made out of a high strength plastic, and are available in a variety of heights, from 2 to 5 inches, allowing for a "custom fit."
If you're considering risers for a chair, you need to be cautious. As most risers are not attached to the foot of the chair, they could slip out and cause the chair to tip over. See our Consumer Guide for more information. A new chair that is more suited to the person's current needs may be your safest bet.
