I can't tell you how many times I've picked up a bed frame and the homeowner says "it started squeaking a few months ago and just got worse." They assumed the whole thing was broken. Usually it's not. Squeaking is annoying, but it's rarely a sign your frame is about to collapse.
That said, squeaking does mean something is wrong. Metal is rubbing against metal. Wood is rubbing against wood. Hardware is loose. Something isn't sitting right. The good news is most squeaks are fixable without replacing the frame. (Ready to fix it now? Jump to my step-by-step fix guide.)
Why I Know What Causes Squeaks
20+ years in the mattress industry. Thousands of bed frames hauled out every year.
The Real Reasons Beds Squeak
Every squeak comes down to one thing: friction. Two surfaces are rubbing together that shouldn't be, or hardware has loosened up enough to let parts move around.
Here's what I see most often:
Loose Bolts and Screws
This is the number one cause. Every bed frame has joints held together by hardware. Over time — we're talking months, not years — that hardware loosens from the nightly movement of getting in and out of bed. Once bolts are loose, the parts they're holding together start to shift. Metal slides against metal. Wood rubs against wood. You get the squeak. This happens even faster with heavier individuals, couples, or more active use — more weight and movement means more stress on those joints.
Metal-on-Metal Contact
This is why metal frames squeak more than wood frames. When two pieces of metal rub together, you get that high-pitched sound that cuts right through the room. The joints are the usual culprit — where side rails connect to the headboard and footboard, where slats sit on the frame, where the center support attaches.
Wood-on-Wood Friction
Wood frames are generally quieter, but they're not immune. Slats rubbing against the side rails. The headboard shifting against the frame. Joints that have dried out and started to move. Wood absorbs vibration better than metal, so the squeaks tend to be lower and duller — more of a creak than a screech.
Slats Moving Around
If your slats aren't secured to the frame — just sitting in notches or on ledges — they'll shift every time you move. That movement creates friction against the frame. I've picked up beds where the slats were practically polished smooth from years of sliding back and forth.
The Mattress Rubbing Against the Frame
Sometimes the frame itself is fine, but the bottom of the mattress is grinding against the top of the frame every time you move. This is more common with firmer mattresses that don't sink into the frame as much.
Uneven Legs or Wobbly Frame
If one leg is shorter than the others, or the floor is uneven, the frame rocks slightly when you move. That rocking creates stress at the joints, and stress at the joints creates noise.
Metal Frames Squeak More Than Wood Frames
This isn't opinion — it's physics. Metal against metal is louder than wood against wood.
Wood has organic fibers that absorb vibration. When two pieces of wood rub together, the sound is muffled. Metal doesn't absorb anything. It transmits vibration. Two pieces of metal grinding together ring out like a bell.
This is why cheap metal frames are notorious for squeaking. They have more joints, more bolts, more places where metal touches metal. And because the metal is often thin gauge, it flexes more under load, which creates more movement at the joints.
Not All Metal Frames Squeak
That doesn't mean all metal frames squeak. Heavy-duty frames with thick steel and welded joints can be dead silent for decades. It's the lightweight bolted-together frames that cause problems.
How to Find Where the Squeak Is Coming From
Before you can fix it, you need to find it. Here's what I tell people:
-
Take the mattress off
Put it on the floor. Now sit on different parts of the frame — corners, edges, middle. Rock back and forth. Listen.
-
Test the frame alone
If the frame squeaks without the mattress, you've confirmed the frame is the problem. If it's silent, put the mattress back and try again. The squeak might be coming from the mattress itself (spring mattresses can squeak) or from friction between the mattress and frame.
-
Go joint by joint
Once you narrow it down to the frame, grab each connection point and wiggle it. Push on the slats. Check the headboard and footboard connections. The squeak will usually reveal itself when you find the loose or rubbing spot.

Now that you understand what's causing the squeak, it's time to fix it. I've put together a complete step-by-step guide to fixing squeaky bed frames — including quick fixes that solve 80% of problems, diagnostic steps, and solutions for mattresses, box springs, and headboards.
What I See in Frames That Never Squeak
After picking up thousands of bed frames, I know which ones stay quiet.
Solid Wood with Real Joinery
Mortise and tenon joints, dowel joints, heavy-duty corner brackets — these hold tight for decades. The wood doesn't shift because there's nowhere for it to go. No shifting means no rubbing means no squeaking.
Welded Metal Frames
When metal parts are welded together instead of bolted, there's no joint to loosen. The frame is essentially one piece. I've picked up old hospital-style metal frames that were dead silent after 30 years because everything was welded.
Platform Beds with Solid Surfaces
A platform bed with a solid plywood or MDF top doesn't have slats to move around. The mattress sits on one continuous surface. No slats means one less thing to squeak.
Frames with Secured Slats
Some frames have slats that are actually fastened down — screwed in, strapped with fabric, or locked into place with clips. These don't shift. They don't rub. They stay quiet.
Heavy Frames
Weight is your friend when it comes to squeaking. A 100-pound solid oak frame doesn't move much under load. A 30-pound flat-pack frame flexes with every movement. Less flex means less noise.
Beds That Are Prone to Squeaking
On the flip side, here's what I see squeaking most often:
Cheap Metal Frames with Thin Steel
The kind you can pick up with one hand. They flex under weight, the joints loosen quickly, and the metal-on-metal contact is constant.
Flat-Pack Furniture with Cam Locks
Those twist-to-tighten cam locks are convenient for assembly but terrible for long-term stability. They loosen over time, and once they're loose, everything starts to shift and squeak.
Beds with Loose Slats
If the slats just sit in notches with nothing holding them down, they're going to move. Movement equals noise.
Old Spring Mattresses on Any Frame
Sometimes the squeak isn't the frame at all — it's worn-out springs inside the mattress. If you've ruled out the frame and the noise persists, the mattress might be the problem.
Preventing Squeaks in the First Place
A few simple habits can keep your frame quiet for years:
Squeak Prevention Habits
- Tighten your hardware regularly. Once or twice a year, go around and check every bolt. This takes five minutes and prevents the loosening that causes most squeaks.
- Don't drag your bed across the floor. Lift it if you need to move it. Dragging stresses the joints and can knock things out of alignment.
- Use a bed frame that matches your weight needs. If you're a heavier sleeper, share the bed with a partner, or the bed sees more "active" use, you need a sturdier frame. Undersized frames flex more under load, which accelerates joint rubbing and hardware loosening — the two main causes of squeaking.
- Check your floor. If your floor is uneven, your frame will rock. That rocking stresses the joints. Use furniture pads or shims to level the frame.
When to Just Replace the Frame
Sometimes a squeak is telling you the frame is done. (Read more about why bed frames fail.)
Signs It's Time for a New Frame
If you've tightened everything, lubricated the joints, added padding, and the squeak keeps coming back — the frame might be worn out. Stripped screw holes can't hold bolts tight anymore. Warped metal won't sit flat. Cracked joints will just keep cracking.
At that point, fixing is just delaying the inevitable. A quality replacement frame will be silent and stay that way for years.
What I Tell People About Squeaky Beds
When someone asks me about a squeaky bed, here's what I say:
Key Takeaways
- Squeaks come from friction and looseness. Every squeak is either two surfaces rubbing or hardware that's worked loose over time.
- Metal frames squeak more than wood. Metal transmits vibration while wood absorbs it. More joints means more noise potential.
- The squeak is telling you something. It's not dangerous, but it means parts are moving that shouldn't be moving.
- Cheap frames squeak more. Thin metal, cam locks, loose slats — these are squeak factories. If you're tired of the noise, a better frame is the real solution.
- Check the mattress too. If you've ruled out the frame and still hear noise, the mattress springs might be the culprit. Memory foam and latex mattresses don't squeak — only spring mattresses do.
