A bed is too low when your knees sit higher than your hips while seated, so raise it until your feet rest flat with knees near 90 degrees.
If you’re tall, climbing into a low bed is a daily strain on your knees and lower back. Getting the height right changes a bed from a struggle to a smooth transition. For most setups, the fastest fix is a set of bed risers, but the right choice depends on how much height you need, your frame’s legs, and how much weight the risers can carry. Here is the measured approach, starting with what works for most people.
Finding Your Target Bed Height
Before buying anything, calculate the number you’re aiming for. The ergonomic target is a sleep surface that lets you sit with your feet flat on the floor and your knees bent at about a 90-degree angle. If your knees are higher than your hips, the bed is too low.
Write it down before shopping—it tells you whether risers alone will work or whether you need a taller frame.
Bed Risers: The Fastest and Cheapest Option
Bed risers are the most common solution because they are inexpensive and install in minutes. They typically add 2 to 12 inches of height depending on the model, with 3 to 7 inches being the most typical range. The installation is straightforward: remove the mattress and bedding, lift one corner at a time, slide a riser under each leg, and repeat for all four corners. Then verify the frame sits level and stable.
Two compatibility checks matter before you buy. First, your bed frame’s legs must seat securely in the riser. Many standard frame legs are hollow, and one manufacturer’s guide states its risers will not work with solid or decorative legs. Angled, non-hollow, or unusually shaped legs may not fit standard risers at all. Second, check the weight limit.
If you’re lifting the frame yourself, use a helper when unsure. After installation, gently rock the frame to check for wobble—if anything feels uneven, it is not safe for long-term use.
When Risers Aren’t Enough: Taller Frames and Other Options
The Sleep Foundation identifies taller frames as the best option for significant increases because they are engineered for the load rather than relying on add-on blocks. A taller box spring is another alternative when risers are incompatible with your setup.
For small gains, a mattress topper can add up to roughly 3 inches while also changing the feel of the bed. An adjustable base is the priciest path, offering personalized height and positioning, but the exact height gain depends on the model. Just verify the usable length rather than the nominal frame length, because some adjustable beds lose length when raised.
A quick note on wedges: pillow wedges elevate the head and upper body for comfort or medical positioning, but they do not raise the overall bed height, so they solve a different problem than the one you’re working on.
Once you’ve raised the bed to the right height, you may find the overall length still feels short. For sleepers who need extra legroom, our roundup of beds designed for big and tall sleepers covers extended-length frames worth considering.
Common Mistakes and the Safe DIY Warning
The most frequent errors are choosing risers without checking leg shape or size, ignoring weight capacity, raising only the head of the bed when the goal is overall height, and skipping the stability re-check after installation. A taller frame that doesn’t match your existing mattress dimensions is another easy miss.
On DIY solutions: homemade blocks, pallets, or cinder-block style lifts appear in casual guides, but the cited sources provide no manufacturer safety ratings for those approaches. Only use them if you can verify the structure is engineered for the load and stable floor contact. When in doubt, stick with rated commercial products.
FAQs
Can bed risers damage my bed frame?
Risers generally do not damage a frame when they match the leg design and stay within the rated weight limit. The risk comes from mismatched legs—solid, angled, or decorative legs may not seat properly, creating instability that can bend or stress the frame over time.
How much height do most people actually need to add?
To find your exact number, measure from your knee to your foot, subtract the current bed height, and add about 1 inch for bedding.
Is it better to raise the whole bed or just the head?
For ergonomic entry and exit, raise the whole bed evenly. Raising only the head tilts the sleep surface and does not solve the seated-height problem that makes getting in and out difficult.
