What is a bed frame?

Bed frames are made of wood or metal and include side panels, headboards, and footboards. Some bed frames include headboards or feet. Bed frames support the mattress. Raising the mattress gives more space in the room, thus making it easier to access.

How to put a mattress on a bed frame? 

For a peaceful sleep and aesthetics in your room, you need a suitable mattress on your bed frame. Once, that’s done, here’s how to do it:

Start by measuring your bed frame and find a suitable mattress. If you do not already possess a bed frame, find one that fits your needs and the size of your mattress. Once the bed frame is complete, place the mattress on top of it. 

Here’s a step-by-step guide to the process:

Step 1. Prior to buying a mattress, measure your bed frame to make sure it can accommodate the mattress.

Step 2. Measure the mattress or read the dimensions online to ensure that it fits the bed frame.

Step 4. Place your choice of mattress on the perfect size bed frame.

The Problems

If your mattress doesn’t fit your bed frame, you can experience two types of problems. Either the mattress is too small or too large, depending on your preference.

The Mattress Is Too Small

In other words, if you buy a smaller mattress than the bed frame, you’ll have the following problems.

  1. A small mattress will leave gaps on the front and back of your bed. In addition, the gaps won’t look nice, so you’ll have no choice but to cover them.
  2. When gaps appear in the bed as a result of small mattresses, people usually try to hide them with pillows. They also cover the gaps with blankets. As a result, these areas look and feel unappealing.
  3. It is possible for your toddler or pet to get injured in the bed if they are roaming around the house. Due to this, beds that have gaps can leave kids or pets trapped. 

Problems When The Mattress Is Too Big

If you didn’t check the measurements beforehand or the mattress or bed frame had the wrong dimensions, you could end up with a larger mattress for your bed. Let’s see issues can occur because of this:

  1. Sometimes, people force mattresses into their bed frames. Thus, the bed looks messy and it doesn’t look good. Plus, sleeping on mattresses that are forced on the bed frame is uncomfortable for them.
  2. It can cause health problems, since sleep is essential for optimal health. Sleeping poorly will negatively impact your health. The most common health problems include back pain, hip pain, and many others. Additionally, it can disrupt sleep, which makes you feel tired the next day.
  3. If your mattress overhangs, a child or pet could get trapped underneath your mattress. 
  4. An overhanging mattress can deform and ruin the support of your mattress. This could also void your warranty.

The Fixes

Let’s jump into the fixes and solutions. There are several ways to fix the different problems, and you can either use tricks to compensate for this problem or change the mattress.

It is not always possible to replace or return a mattress. We always say you should get a mattress in a box, because they always offer trial periods. Check out our Puffy vs Puffy hybrid review

Here are our solutions:

Method 1: Fill In The Gap Between The Mattress And The Frame

It’s really uncomfortable to sleep on a mattress that doesn’t fit perfectly on your bed frame. Sleeping with your head or pillows through the gap between your mattress and bed can affect your sleep.

Therefore, it needs to be fixed as soon as possible. How can you feel the gap between the mattress and the bed frame? Adjust the headboard to fill the gap between the mattress and bed if possible. You can also use decorative pillows or buy a suitable gap filler to fill the gaps.

Let’s see how we can fill this gap step by step below:

Step 1

Adjust Headboard: If your bed frame has an adjustable headboard, lower it to your liking.

Step 2

Use Pillows: If your bed is large enough, place large or decorative pillows against the headboard to fill in gaps.

Step 3

Get a Gap Filler: Buy a gap filler of your choices, such as pillow stops or wood boards. Install them according to the instructions.

Method 2: Removing The Gaps (DIY Method) 

You must fix the gaps in your bed. The gaps cause minor injuries to many kids and adults every year. You’ll need to fix them. You shouldn’t have any trouble doing it. Let’s get started: 

Let’s examine the tools for the job: 

Step 1: To begin with, check your bed’s mattress

There will be a gap if there is any mismatch in the mattress’s size. When ordering a mattress, a mismatch in size will result in gaps, so keep that in mind.

How should a mattress fit on a bed frame?

A mattress should be of an exact fit in your bed frame. This means that it shouldn’t be large or small. It’ll have no gaps, and the mattress should never hang off the sides of the bed as well. 

Step 2: Block Any Gap 

Instead of buying a new mattress, you can try filling the gaps or blocking them gaps. How do you fill the gap between the mattress and bed frame? 

Fix boards 2-3 inches thick in the headboard at the top of the mattress. This will free up a lot of space. The number of boards you build will depend on how big the gap in your bed is.

In contrast, you can push the mattress to the top and install gap boards on the footboard. Whatever the case, just try to fill in the gaps without using any pillows.

Step 3: Add Padding In The Headboard 

Try padding if you wish to fix the gaps in your bed and enhance the décor of your room. Add padding to the headboard. You can use foam padding. Consequently, the gap will be filled easily. This will also prevent the pillows from moving around. Additionally, it will give the old headboard a new lease of life.

Ensure, however, that your children or others are aware of the gap in that place. You are not filling the gap and hiding the gap in the place. Stepping or falling on that place can cause someone to hurt themselves.

Step 4: Remove The Headboard

If the mattress doesn’t fit properly, remove the headboard. In this way, your bed frame will have more space. 

Toss the bed against the wall once you remove the headboard. Tossing the headboard means you’ll have more space in your bed frame. The headboard can even be replaced with a folding screen if you wish.

Method 3: Purchase A Mattress Extender 

When you decide to buy mattress extender products, you might wonder about the details. We’ve gathered all the information you need about the top products you should try:

FAQ

Is it normal for mattress sizes to be off by a few inches?

We have seen many differences in mattress sizes in recent years. The industry regulates some of the published mattress sizes, but mattresses do not always follow those standards. 

There are, however, definite reasons why the mattress may break off from the company whose products appear to be smaller than advertised. 

There are times when the length and width are too short. This is not limited to the more recent products or the boxes. Tradition brand names may vary by dozens of inches in some instances. 

Always ask for a discount when the height is more than that.

How to Keep Mattress From Sliding

Trying to get to sleep on a mattress sliding around is a nightmare. It will also result in poor sleep quality; luckily, we have a few ways to stop your mattress from sliding around all night.

One of the best ways is to use carpeting tape, but let’s get more specific below.

Prevent a mattress from sliding on a metal bed frame

When carpeting tape isn’t enough, your mattress can move. This can be the case with a metal frame, the best option for these designs is generally a side rail system. 

These can be made by you. You can use elastic straps as mattress stops. Strip the mattress off its covers and wrap a strap around it. If you have a mattress topper, place the strap underneath it.

Prevent a mattress from sliding in a box spring

Velcro or carpet tape, rubber mats or vacuuming are the only alternatives when working with box springs. If all else fails, non-slipping mattresses may also prove useful.

How can a mattress be kept from sliding on a platform bed?

You must have proper bed support for mattress sliding platforms. If your mattress is too big for your bed, the pillow may slide off. The pillow will keep your mattress from slipping. You can also use mattress straps.

Verdict

That’s all we have for you today. Hopefully, we have clarified why the mattress won’t fit the frame. 

In conclusion, we would like to remind you to always check the mattress size comparison before ordering a mattress. You can follow these fixes if you don’t get the right size mattress—best of luck.
