Most beds are sold at one height and then left alone. The person who uses it is shorter, taller, slower, or stiffer than the person who bought it, and nobody has checked. This piece shows you how to measure the bed and the chair in the same afternoon and decide what to change.

Measure the bed and the chair

Measure from the floor to the top of the mattress, with the mattress on the frame and with the bedding you actually use. Then measure the seat height of the chair your parent sits in most, from the floor to the top of the seat cushion. Write both numbers down. Note the difference. A bed that sits much higher or much lower than the chair makes the move from sitting to lying down a daily effort.

Check the room around the bed

Measure the space on each side of the bed and at the foot. You need room for the walker, for a caregiver to stand beside the bed, and for a clear path to the bathroom door. Check that the bed does not block a doorway or the path to the nightstand. If the bed is pushed against one wall to make room, check that the side your parent uses still has space to stand.

Compare the fixes

There are three common fixes: a lower or higher frame, a riser or raised base, or an adjustable bed. Each one changes the height, the cost, and the set-up time, so compare them on the same sheet. Check the weight limit and the return policy before you buy. If a bed rail or raised frame is on the table, ask your parent's doctor or therapist before you buy, and follow the manufacturer's instructions for installation.

Test it before you call it done

Have your parent sit on the chair, stand, walk to the bed, sit down, and lie back. Do it three times, slowly. Watch for the place where they reach for something, lean on the nightstand, or pause. Those are the spots to fix before you move anything else.
