How to Use Bed Risers | A Safe Setup Guide

Bed risers lift a bed by placing one under each leg or caster, and safe use depends on proper fit, correct quantity, and a stability check.

For the full breakdown, see our best 12 Inch Bed Risers guide.

Bed risers are a simple, affordable way to add storage space underneath your bed or make getting in and out easier. The key to using them safely comes down to three things: choosing the right riser for your bed’s legs, using enough of them, and confirming everything is stable before you climb in. Here’s what you need to know to set yours up correctly.

Choosing the Right Riser for Your Bed

The most important step happens before you lift a single corner. Bed risers come with different indentation sizes and shapes on top, and the one you choose must match your bed’s legs or casters. If the leg fits loosely, the bed can shift and become unstable.

Look at the bottom of your bed frame. Measure the width and shape of each leg or caster, then compare it to the wells on the riser. The leg should sit deeply inside the indentation rather than resting on the rim. Kingston and Richmond NHS Foundation Trust’s patient guidance on bed raisers recommends selecting the indentation that most closely matches the leg or caster so it fits deeply and cannot slip out.

One riser goes under each leg. If your bed frame has more than four legs—some platform beds and larger frames do—you need one riser per leg. Skipping a leg puts uneven pressure on the frame and can cause it to bow or break.

Step-by-Step Installation

Installing bed risers is a two-person job. The official guidance from the NSW Clinical Excellence Commission’s equipment safety document recommends two people for installation, and it’s easy to see why: lifting a mattress and frame alone strains your back and makes it harder to seat the risers properly.

1. Clear the area. Remove anything under the bed that could snag, and make sure the floor is clean and level.
2. Lift one corner of the bed. Have your helper lift together so the leg clears the floor.
3. Place the riser. Position it so the leg or caster drops into the indentation. If you have casters that don’t fit well, remove them and place the bed leg directly into the well instead.
4. Repeat for each leg. Work around the bed, placing one riser per leg.
5. Lower the bed gently. Do not drop it—lower each corner slowly so the legs seat into the risers rather than knocking them out of place.
6. Check stability. Press down on each corner, then sit on the edge of the bed. If anything shifts, wobbles, or feels off, lift that corner and reseat the riser.

After you’ve moved the bed—even just to vacuum underneath—re-check that all legs are still seated. Small movements can alter alignment, and a leg sitting half-out of its well is a collapse waiting to happen.

When NOT to Use Bed Risers

Bed risers aren’t a universal solution. The NSW and NHS guidance is clear about situations where they should not be used:

• Uneven or weak flooring: Risers concentrate weight into small points. Carpet is generally fine, but avoid placing them on soft, uneven, or damaged flooring where they can sink or tip.
• Missing legs or castors: If a leg is broken or missing, do not use a riser to prop up that corner. Replace the leg first.
• Riser recliners and hospital-type electric beds: These beds raise and lower sections of the mattress, and using risers with them can destabilize the mechanism or create dangerous pinch points.
• Any bed that shifts: If the bed moves when you get in or out, or when you sit on the edge, the risers aren’t working. Stop using them.

Also inspect your risers before each use. If they’re cracked, chipped, or otherwise compromised, replace them—a damaged riser can fail under weight without warning.

Checking Your Setup Works

Your bed is ready only when it passes the stability test. Sit on the edge, roll over, get in and out a few times. A properly installed riser setup feels exactly like the bed did before—just higher. If you notice any shift, lift that corner and reseat the leg in its well.

That difference turns dead space into usable storage or makes that tall platform bed finally feel accessible. The extra height is worth nothing, though, if the bed isn’t stable—so always prioritize fit and security over a few extra inches.
