At 3am, do not start taking the bed apart.
If your mother has fallen, handle the fall first. Check her condition before you move her or change the room. Use the first ten minutes after a fall as your order of work.
If she is safely back in bed, turn on enough light to see the floor. Walk the route in order: bed, place to stand, bedroom doorway, hall, bathroom doorway, toilet. Remove only an obvious item that can be lifted away without moving furniture or changing the bed. Do not ask her to repeat the trip so you can watch.
Then leave the room quiet. You can measure in daylight.
The price starts with the problem you are solving
“Lower the bed” is not yet a useful request for a seller, installer or handyman. First decide which part of the movement is failing.
Is she sliding forward before her feet reach the floor? Is she able to sit but unable to rise? Does she stand and immediately reach for a dresser? Does the mattress edge collapse under her? Does she become unsteady only after turning toward the bathroom?
Those are different problems. A lower surface may change how she gets down, while also changing how she stands back up. Ask her physician, physical therapist or occupational therapist what bed height and transfer setup they want her to use. Bring your measurements and observations. Do not ask a furniture salesperson to make that clinical decision. The public references used for this desk are collected on the sources page.
Measure the bed that exists
In daylight, measure from the floor to the top of the mattress without anyone sitting on it. Then write down the separate heights of the frame, foundation and mattress. Note whether the frame has legs, wheels, storage drawers or an adjustable base.
Do not stop at the bed measurement. Measure the clear standing space beside it. Measure the narrowest point between the bed and any dresser, chair or wall. Check where the lamp cord, phone charger and any other cable cross or approach that space.
Now walk all six stops. A changed frame can shift the mattress sideways, alter the open floor beside the bed or require a different location for a table. Your quote should cover the route you will actually have after the work, not an isolated piece of furniture.
Ask for one complete number
Give each seller or installer the same written scope. Ask whether the quoted amount includes the frame or other parts, delivery into the bedroom, assembly, removal of packaging, removal of the old parts and a return visit if the setup is incomplete.
Ask these questions before comparing totals:
Will the existing mattress and foundation fit the proposed setup? Must either one be replaced? Will existing attached equipment still fit, or must it be removed? Is moving the old frame included? Are stairs, a tight turn or a distant parking space handled in the quoted work? Who is responsible if the parts arrive but cannot be used in this room? What return or restocking terms apply after delivery? Who pays for a second visit if a missing part stops assembly?
Do not compare one quote that includes delivery and removal with another that covers only a boxed frame. Put each answer on one line. A blank is not a no. It is an unanswered cost.
Look for the costs created by the change
A different bed height may require more than a different frame. Check whether sheets still fit, whether under-bed storage must move, whether the bedside table remains usable and whether the light can still be reached before she stands.
Check the floor after the old setup is removed. If the new footprint exposes a curled rug edge, a cord or damaged flooring, put that correction into the same scope before the job begins.
If someone suggests adding a step so she can reach the bed, stop and take that proposal back to her clinician. The question is whether the complete transfer works for your mother, not whether a piece of furniture can be made reachable.
Make the decision on paper
Use four columns: proposed setup, work included, work excluded and what happens if it does not fit. Add a fifth column for the total you would owe if the first installation cannot be completed.
Choose only after you can identify who measures, who supplies each part, who assembles it and who takes responsibility for a mismatch. Keep the order, receipt, dimensions, return terms and installer contact together in one drawer.
If the answers remain vague, do not buy that night. Use the existing setup only as her clinician has directed, arrange whatever supervision the night requires, and make the calls in daylight. For St. Louis area services and public contacts, use Local help after a fall.
What to write down before the appointment
Write the time she tried to get up, which side of the bed she used and whether she sat first. Record whether both feet reached the floor, what her hands reached for, whether she rose on the first attempt and where the first unsteady moment occurred.
Continue through the six stops: bed, standing place, bedroom doorway, hall, bathroom doorway, toilet. At each stop, write what she touched, where she paused and whether the trouble happened while rising, walking, turning, opening the door, lowering or standing again.
Add the bed, frame, foundation, mattress and clear-floor measurements. List any recent change in the room or in how she moves. Bring that one page to the clinician. It gives the clinical question a location and a movement, and it gives the person quoting the work a defined scope.
The purchase decision comes last. First identify the failed movement. Then get the clinical instruction. Then price every part of the change.
