Bed height seems like a minor detail until someone struggles to get up in the morning or sits down too hard at night. For older adults, the right bed height can reduce strain on knees and hips, make transfers safer, and lower the risk of falls. The wrong height, whether too low or too high, can turn a routine movement into a hazard. This guide explains how to measure the ideal bed height for an older adult, the common adjustments, and how to account for mobility aids and health conditions.
Quick answer: Our top pick in 2026 is the 16 to 19 inches — our #1 rated choice. See the full ranked comparison, alternatives and buying advice below.
Why Bed Height Matters for Seniors
Getting in and out of bed is one of the most frequent transfers a person makes each day. If the bed is too low, the user must push through deeply bent knees and hips, which demands leg strength and balance. If it is too high, their feet may not touch the floor when sitting on the edge, making it hard to stabilize before standing. Both situations can increase fall risk.
How to Measure the Ideal Height
The general guideline is that when the person sits on the edge of the mattress, their feet should rest flat on the floor and their knees should be at about a 90-degree angle, with hips level with or slightly above the knees.
- Have the person sit on a firm chair with feet flat and knees at 90 degrees.
- Measure from the floor to the back of the knee (popliteal height).
- Add about 1 to 2 inches to allow for mattress compression.
- That figure is approximately the ideal top-of-mattress height when sitting.
For many adults, this results in a mattress-top height between about 20 and 23 inches from the floor, but it varies with height and leg length.
Typical Heights and Who They Suit
| Mattress-top height | Often suits | Considerations |
|---|---|---|
| 16 to 19 inches | Shorter adults, those at high fall risk from bed | Reduces fall distance but harder to stand up |
| 20 to 23 inches | Average-height adults | Balanced for sitting and standing |
| 24 to 26 inches | Taller adults or those with knee/hip issues | Easier to stand; feet must still reach floor |
| Adjustable (hospital-style) | Users needing caregiver assistance | Can lower for safety, raise for care tasks |
Ways to Adjust Bed Height
Raising a bed
- Bed risers: sturdy blocks that lift each leg 3 to 6 inches. Choose wide, stable risers with a recessed cup for the leg.
- Thicker mattress or topper: adds a few inches but can change firmness.
- New bed frame: some frames come with adjustable leg heights.
Lowering a bed
- Remove the box spring and use a platform frame.
- Choose a low-profile foundation.
- Consider a thinner mattress if firmness allows.
Adjustable and hospital-style beds
For people with changing needs or caregivers helping with transfers, a height-adjustable bed can be lowered for sleeping and raised for care tasks. These beds can reduce caregiver back strain as well.
Special Situations
Using a walker or wheelchair
For wheelchair users, a bed height roughly level with the wheelchair seat makes lateral transfers easier. For walker users, the bed should allow them to stand and grasp the walker without leaning far forward.
After hip or knee surgery
Surgeons and therapists often give specific precautions about how far the hip can bend. A slightly higher bed may be recommended during recovery. Follow the care team’s instructions closely.
Cognitive impairment or high fall risk
For some people who may try to get up at night unsafely, a lower bed can reduce injury risk. Families sometimes pair a low bed with a floor mat. Discuss options with the care team.
Other Safety Tips
- Place a nightlight between the bed and bathroom.
- Use a bed rail or assist handle if recommended.
- Keep a phone, glasses, and water within reach.
- Remove rugs or clutter near the bed.
Frequently Asked Questions
What is a good bed height for an elderly person?
A good bed height lets the person sit on the edge with feet flat on the floor and knees at about 90 degrees. For many adults, this is around 20 to 23 inches from the floor to the top of the mattress.
Are bed risers safe for seniors?
They can be when chosen carefully. Use sturdy, wide risers rated for the bed’s weight and check that the bed does not wobble. Avoid stacking risers or using makeshift supports.
Bottom Line
Choosing the right bed height is a simple, low-cost way to make daily transfers safer for older adults. Measure from the floor to the back of the knee, add a little for mattress compression, and adjust with risers, frames, or an adjustable bed as needed. Revisit the height as mobility changes.
