Hospital beds have a straightforward set of controls, but knowing how to use each feature correctly makes a real difference in comfort, safety, and daily tasks like eating, breathing, and getting in and out of bed. Whether you’re setting one up at home or helping a family member in a care facility, here’s what you need to know.
Understanding the Hand Control
Electric hospital beds come with a wired pendant remote, usually clipped to the side rail or mattress edge. The buttons are grouped by section and marked with simple icons and arrows. There are three main adjustments:
- Head (backrest): Up and down arrows raise or lower the head section of the bed. This is the control you’ll use most often.
- Leg (knee/foot): Up and down arrows raise or lower the section under the knees and feet. Raising the legs slightly can reduce swelling and improve circulation.
- Bed height: “Bed Up” and “Bed Down” buttons raise or lower the entire frame. This doesn’t change the angle of the mattress, just how high it sits off the floor.
Some models combine these into a single panel with six buttons; others add a “flat” or “reset” button that returns everything to a neutral position. After a few uses, the controls become intuitive. If you’re setting up the bed for the first time, test each button before anyone lies down so you know which direction everything moves.
Adjusting the Bed Height for Transfers
The height control exists primarily for two purposes: making it easier for a patient to get in and out of bed safely, and bringing the mattress to a comfortable working height for caregivers. For transfers, the ideal bed height matches the patient’s knee height so their feet rest flat on the floor when sitting on the edge. Average knee height is about 21 inches for men and 19.5 inches for women, though you should adjust to whatever lets the specific person’s feet touch the ground without dangling.
When the bed is not being used for a transfer, keep it in the lowest position possible. This is a consistent recommendation from patient safety organizations because it reduces the distance and impact of a fall if someone rolls out or tries to stand unassisted. If the person in the bed is at risk of falling, a low bed position is one of the simplest and most effective precautions you can take.
For caregivers, raise the bed to about waist height when you need to change linens, reposition the patient, or provide wound care. Working at the right height protects your back. Lower it again when you’re done.
Common Bed Positions and When to Use Them
Hospital beds aren’t just for lying flat. The ability to adjust the head and leg angles lets you set specific positions that help with breathing, digestion, and recovery.
Semi-Fowler (30 to 45 Degrees)
Raise the head of the bed to roughly 30 to 45 degrees with the legs flat or slightly bent. This is one of the most commonly used positions. It helps people who have difficulty breathing, acid reflux (GERD), or a feeding tube. The gentle incline keeps stomach contents from flowing back into the esophagus and opens the chest for easier breathing. If you’re not sure what angle you’re at, 30 degrees is about a third of the way from flat to fully upright.
Standard Fowler (45 to 60 Degrees)
A steeper incline of 45 to 60 degrees is used when someone needs even more help breathing, or after surgery on the head, shoulders, or chest. It places less pressure on the lungs and diaphragm.
High Fowler (60 to 90 Degrees)
This is essentially sitting upright in bed. Use it during meals, since the upright posture helps with swallowing and reduces the risk of choking. Lower the bed back to a gentler angle after eating.
Legs Elevated
Raising the leg section while keeping the head flat or slightly raised helps with leg swelling, poor circulation, and post-surgical recovery in the lower body. Even a moderate elevation makes a noticeable difference in comfort for people who retain fluid in their legs and feet.
Using Side Rails Safely
Most hospital beds have side rails that fold up and down. Some run the full length of the bed, while others are split into shorter sections at the head and foot. Split rails are common on home hospital beds because the upper section can stay raised to prevent rolling out while the lower section stays down, making it easier to swing legs over the side.
Side rails are useful as grab bars during repositioning and as a reminder not to roll too close to the edge. However, the FDA has identified seven potential entrapment zones around hospital bed rails, places where a person’s head, neck, or chest could become trapped between the rail and the mattress, between split rails, or in gaps between the rail and the headboard. The most dangerous gaps are those wider than about 4.75 inches, which is large enough for a head to pass through and become stuck.
To reduce this risk, make sure the mattress fits snugly against the rails and headboard with no large gaps. If you can fit a fist between the mattress edge and the rail, the mattress is too narrow or has shifted. People who are confused, restless, or heavily sedated are at the highest risk. For these individuals, use caution with raised rails and consider alternatives like a low bed position with a mat on the floor beside it.
Choosing the Right Mattress and Sheets
Standard hospital bed mattresses measure 36 by 80 inches, the same as a twin XL. Regular twin sheets (36 by 75 inches) will be too short and will pop off every time you raise the head or foot section. Look for twin XL fitted sheets with a pocket depth of at least 9 to 10 inches, which accommodates most hospital mattresses and stays in place when the bed is articulated.
The mattress itself matters for skin health. If the person spends most of the day in bed, a pressure-relieving mattress (foam, alternating air, or gel) helps prevent pressure sores. A standard innerspring hospital mattress is fine for someone who moves around regularly and gets out of bed during the day.
Weight Limits and Bed Width
Standard hospital beds typically support up to about 350 pounds. Bariatric models are rated for 500 pounds or more and are wider, usually 42 to 54 inches compared to the standard 36 inches. If the person using the bed weighs more than 325 to 350 pounds, a bariatric bed is generally the safer choice, both for weight capacity and because they need the extra width to turn and reposition comfortably. Research suggests that people with a BMI above 35 who have difficulty repositioning themselves benefit from a wider surface, while those who can move independently may be fine on a standard-width bed up to a BMI of about 45.
Cleaning the Bed
Hospital bed frames should be wiped down regularly, especially the side rails, control pendant, and any surfaces the patient or caregiver touches frequently. The CDC recommends cleaning and disinfecting both the frame and mattress surface. A dilute bleach solution (no stronger than 1,000 parts per million, which is about one tablespoon of standard household bleach per quart of water) works well for the frame, but rinse metal parts with clean water afterward to prevent corrosion. Alcohol-based wipes (60 to 80 percent alcohol) are good for the remote control and small components, though avoid soaking rubber or plastic parts, which can degrade over time.
For the mattress, check the manufacturer’s label. Most hospital mattress covers are waterproof vinyl or nylon and can be wiped with the same disinfectant. Make sure the cover is intact with no cracks or tears, since a compromised cover lets fluids seep into the foam and creates a hygiene problem that’s difficult to fix.
Practical Tips for Daily Use
Lock the wheels before anyone gets into or out of the bed. Unlocked wheels are one of the most common causes of falls during transfers because the bed rolls away as the person shifts their weight.
Keep the hand control within easy reach but secured so it doesn’t slide between the mattress and the rail. Some people clip it to a pillowcase or attach it to the rail with a Velcro strap. If the person in the bed is confused and might accidentally activate the controls, some models have a lockout switch on the foot end that disables the pendant.
Check the power cord routing. The cord should run from the bed to the wall outlet without crossing a walkway. Tripping over a hospital bed cord while carrying supplies or helping someone stand is a real hazard, particularly at night. If the bed has a battery backup, the batteries typically last about four years before needing replacement, which gives the bed enough reserve power to make basic adjustments during a brief power outage.
Reposition anyone who can’t move independently at least every two hours. The bed’s adjustable sections help, but they don’t replace turning from side to side. Alternate between slight left tilt, slight right tilt, and back, using pillows to hold the position. Raising the head slightly between turns keeps the person comfortable without leaving them in one position long enough for skin breakdown to start.
