When someone spends most of the day in bed, the surface under them matters as much as the frame. A support surface is a mattress or overlay built to spread weight differently from an ordinary mattress. Choosing one comes down to four questions: who pays, what it is rated to hold, how it runs, and how it leaves the house. Most families who regret an order skipped one of those four.

Local option: New Plan Care gives families in the St. Louis area in-home help so a parent can stay home: companionship, help with bathing and dressing, meals, and overnight care. Call (314) 405-0887.

Start with who pays

Before you look at any product, ask the hospice nurse or the hospice office one question: is this item one the hospice furnishes under the hospice benefit for the terminal illness? If the answer is yes, the hospice is responsible for supplying it, and the family should not be buying it. If the answer is no, ask whether a Medicare equipment rule could apply through the doctor's order, and what paperwork that requires. Get the answer in writing, with the name of the person who gave it.

Do not assume a product is covered because the supplier's catalog lists it or a salesperson calls it medical grade. Medical grade is a sales phrase unless the supplier can name the rule the product meets.

Check the rating against the actual person

Every surface has a maximum user weight on the label or the spec sheet. Write down the weight of the person who will use it and check it against that rating. Ask whether the rating applies to the surface alone or to the surface on this bed frame, since some overlays are rated only for specific frames. Ask for the printed spec sheet that comes in the box, not a summary from a website.

Check how it runs at night

A powered surface has a pump or blower that runs for hours. Ask how loud it is on the setting you will actually use, whether it has a night mode, and what happens when the power goes out. Ask whether there is a manual setting that works without electricity, and what the surface does if the pump fails: does it lose firmness slowly, hold its shape, or drop support at once. Ask who services the pump and how long a replacement takes. Then ask the supplier to demonstrate every setting on the unit in your house, not in a showroom.

A foam overlay has no pump to fail, but foam wears down and changes shape over time. Ask how long the supplier rates it to last and what they do when it passes that point.

Check the cover and the cleaning

The cover is the part that meets the sheets and gets cleaned most often. Ask which cleaners are approved for it, whether it can be washed or only wiped, and whether a replacement cover is sold separately and at what price. A cover that cannot be cleaned as often as your household will need it becomes a problem quickly.

Ask how it leaves the house

Ask who picks the surface up when it is no longer needed, whether pickup carries a charge, and whether the supplier will take back a unit that has been used. Read the return window and the warranty period before you pay, because those are the two terms most families only read after they need them. Keep the receipt, the warranty and the spec sheet together in one folder.

Compare two offers on one sheet

When you have two offers, put them side by side with the same rows: who pays, weight rating, noise and power behavior, what happens in a power cut, cover cleaning, replacement parts, and pickup and return terms. Leave blank any row the supplier will not answer in writing. A blank row is information. The offer that answers every row is the one to trust, even when its price is higher, because the rows left empty are the ones that cost money later.

You do not have to decide in one phone call. Get the coverage answer first, then the rating, then the pump, then the exit. The order matters, because a no on coverage can settle the question before you spend another hour on it.
