Why and when to raise a bed frame

Raising a bed frame means adding height between the floor and the mattress, usually with legs, blocks, or a platform. You might do this to fit storage underneath, improve airflow around the mattress, make getting in and out easier, or straightforward create more usable space in a small room. The method you choose depends on your frame type, how much height you need, and what weight it must support.

Before you start, check your frame's weight capacity and the weight of your mattress and bedding. Most standard bed frames hold 300 to 500 pounds, but this limit applies to the entire setup. If you're adding storage underneath, account for that weight too. Raising the frame also changes how it looks and feels in the room, so measure the final height before you commit.

Key Takeaways

  • Bed risers (plastic or wood blocks that slip under existing legs) are the fastest method and work with most frame types without tools.
  • Measure your current frame height and add the riser height to confirm the final height will work in your space and with your mattress.
  • Wooden blocks or cinder blocks are cheaper than commercial risers but require you to may support they sit level and stable under each leg.
  • Platform beds and adjustable frames have their own raising methods—check the manufacturer's instructions before adding risers.
  • Test stability by pressing down on each corner of the raised frame before loading it with a mattress and bedding.

Using bed risers for quick height gain

Bed risers are the simplest method. They are plastic or wood blocks, usually 3 to 12 inches tall, with a cup-shaped top that holds the bed leg. You slide the riser under each leg, and the frame sits higher. No tools, no assembly, and you can remove them anytime. Most risers cost between $15 and $40 for a set of four.

To install risers, first empty the bed completely—remove the mattress, box spring, and bedding. Lift one corner of the frame slightly and slide the riser under the leg. Lower the frame onto the riser. Repeat for all four corners. Make sure each riser sits flat on the floor and the leg sits centered in the cup. If the leg rocks or slides, the riser is not positioned correctly.

Check that the frame is level by placing a spirit level across the top rails. If one side is higher than the other, adjust the risers until the frame is even. An unlevel frame puts stress on the joints and can damage the mattress over time. Once all four corners are stable, test the frame by pressing down firmly on each corner—it should not shift or wobble.

Building height with wooden blocks or cinder blocks

If you have wood scraps or cinder blocks on hand, you can raise a frame for almost no cost. This method works best if you are comfortable stacking materials and checking for stability. Wooden blocks (4x4 posts or 2x4 lumber cut to length) are lighter and easier to adjust than cinder blocks, but both work if they are solid and level.

Stack your blocks directly under each leg. Start with one block per leg, then add more if you need extra height. Before you load the bed, test each stack by pressing down hard—blocks should not shift or crack. If a block moves, remove it and reposition it until it sits flush against the floor and the leg. Uneven stacks will cause the frame to rock.

Wooden blocks can rot or splinter over time, especially in damp basements. Cinder blocks are more durable but heavier and harder to adjust if you need to change the height later. Neither method looks as finished as commercial risers, but both are stable if installed carefully. Keep a level handy and check the frame after a few weeks—blocks can settle slightly as weight distributes.

Raising platform beds and adjustable frames

Platform beds (frames with a solid wood or metal surface instead of a box spring) and adjustable frames have different raising rules. Platform beds can usually accept risers under the legs, just like standard frames, but check the manufacturer's weight limit first. Some platforms are designed to sit low and may not be rated for the extra stress that raising creates.

Adjustable frames (motorized beds that tilt and recline) should not be raised with standard risers. The motor and hydraulics add weight and complexity, and raising them can damage the mechanism or void the warranty. If you need height with an adjustable frame, contact the manufacturer to ask about approved legs or risers. Many sell their own height-adjustable bases designed for the motor and weight distribution.

For both types, read the manual before adding anything under the frame. Some manufacturers specifically forbid modifications, and raising an unsupported frame can cause it to fail under normal use.

Measuring and planning the final height

Before you buy risers or blocks, measure your current setup. Measure from the floor to the top of the mattress with the bed fully made (mattress, box spring if you have one, and sheets). This is your starting height. Then measure from the floor to the top of the bed frame itself, without the mattress. This tells you how much of your current height comes from the frame and how much from the mattress.

Decide how much higher you want to go. Common heights are 18 to 24 inches from the floor to the top of the mattress for easier entry and exit, or 12 to 18 inches if you mainly want storage space underneath. Add your desired riser height to your current frame height, then subtract your mattress thickness. This tells you what riser size to buy.

For example: if your frame is 8 inches tall, your mattress is 10 inches thick, and you want the top of the mattress at 22 inches, you need risers that are 4 inches tall (22 minus 18 equals 4). Write this number down before you shop—riser heights vary, and buying the wrong size means a wasted trip.

Checking stability and weight distribution

After you raise the frame, stability is everything. An unstable raised bed is dangerous—it can collapse under weight or shift suddenly when you get in or out. Test it before you put the mattress back on. Press down hard on each corner of the frame. It should not move, creak, or shift. If it does, stop and fix the problem before proceeding.

Make sure each riser or block is touching the floor at all four corners. If a riser rocks or a block is tilted, the weight is not distributed evenly, and the frame will fail. Use a level to check that the frame is even side to side and front to back. An unlevel frame puts extra stress on one leg and can cause it to fail first.

Once the frame is stable and level, load it gradually. Put the mattress on first, then add bedding and pillows. Get into the bed slowly and check for movement. If the frame shifts or creaks under your weight, get out when ready and investigate. Tighten any bolts or fasteners on the frame itself—sometimes raising a frame exposes loose hardware that was not a problem at the original height.

Removing or adjusting raised frames later

One advantage of risers is that they are reversible. If you decide you do not like the height or need to move the bed, you can remove the risers in minutes. Lift each corner of the frame slightly and slide the riser out. The frame returns to its original height with no damage.

Wooden or cinder blocks are also removable, but they are heavier and take longer to adjust. If you think you might want to change the height later, commercial risers are worth the cost because you can swap them for different heights without much effort. Some risers also come in multiple heights, so you can buy a set and use only the height you need.

If you raise the frame and later find that the height does not work for you, do not force it. Lowering the frame is just as straightforward as raising it. The goal is a bed that is comfortable and safe, not a specific height.

Frequently Asked Questions

Can I use bed risers on a bed frame with wheels or casters?

Yes, but remove the wheels first. Risers are designed to sit on the floor, not on wheels. If your frame has removable casters, take them off and install the risers under the legs. If the wheels are bolted on, you may need to unbolt them. Check your frame's manual for removal instructions.

What is the maximum safe height I can raise a bed frame?

Most commercial risers max out at 12 inches, which raises a standard frame to about 20 to 24 inches total. Stacking multiple risers or blocks can go higher, but the taller the frame, the less stable it becomes and the harder it is to get in and out safely. Stay within the manufacturer's weight limit and keep the frame level—these matter more than absolute height.

Will raising my bed frame damage the legs?

No, if you use proper risers or blocks that fit the leg diameter and distribute weight evenly. Damage happens when risers are too small (concentrating pressure on a tiny area), too tall (creating leverage that stresses the joint), or unstable (causing the leg to rock back and forth). Use risers designed for your leg size and check stability before loading the bed.

Can I raise a metal bed frame the same way as a wooden one?

Yes. Metal frames work with the same risers and blocks as wooden frames. The main difference is that metal legs are often thinner, so make sure your risers have a cup or opening that fits the leg diameter. Some risers are adjustable and work with both thick and thin legs—check the product description before buying.

Do I need to do anything special if I raise the frame in a rental apartment?

Risers and blocks leave no marks or damage, so they are safe for rentals. You can install and remove them without permission or tools. If your lease forbids modifications, risers do not count as a modification because they are fully reversible. Keep the original legs in case you need to return the frame to its original height when you move.
