Zippered Trundle Bed Mattress Covers

A trundle bed is a great way to save space in your home, especially for those living in small studios or apartments. These beds have become very popular in the last decade, and they are most commonly found in children’s bedrooms. Typically, trundle beds have a parent bed and an underbed that can slide in and out on rollers. The underbed for popup trundle beds can be slid out from under the main bed and also raised to the height of the parent bed.

Zippered trundle bed mattress covers keep pop-up trundle beds from separating, they also reduce stains, prevent bed bugs, reduce allergies, and provide additional comfort to your trundle bed.

However, finding a comfortable trundle bed mattress cover can be very difficult due to the huge variety of options available on the market, and the tons of features each one brings to the table.

What is a Pop-Up Trundle Bed?

When researching trundle beds, you are likely to see pop-up trundle beds a lot in the articles you read. But what exactly does this mean? As you probably know by now, traditional trundle beds hold a bed underneath a bed.

A pop-up trundle bed is a bed that can be pulled up to match the height of the primary bed when in use, and when not in use, it can be hidden away underneath the primary bed.

Whenever you need it, the bed underneath can slide out using rollers and be used for guests. However, a pop-up bed is different and is a bit more advanced.

When it comes to pop-up trundles, they can be found as a full-size, twin, or even a set of bunks. Just like trundles, the process begins by pulling the lower bed out on rollers until it is completely free from the upper bed. The difference is, rather than staying lower to the ground than the main bed, the second bed can ‘pop-up’ and be lifted to the level of the primary bed to double the size of the bed.

The benefit of a pop-up is its ability to become one large sleeping area when needed while using just a small amount of space regularly.

Also, while a pop-up is handy, it is not as simple as it seems, and people have reported a few problems with this bed.

One of the main disadvantages of some pop-ups is that, while there is a larger bed, it is not ONE. The larger bed consists of two smaller sized frames and mattresses set up beside one another. That means there are two frames to deal with, and some people aren’t comfortable with that.

Keep pop-up trundle beds from separating by using zippered trundle bed mattress covers.

How to use a Zippered Trundle Bed Mattress Cover

It isn’t difficult to use a zippered trundle bed mattress cover; however, we’ll explain it in detail.

To use a zippered trundle bed mattress cover, use these three steps below to zip up two mattresses into one after popping up the bed frame.

Step 1. Make an L Shape with Your Mattresses To Make It Easy To Slip On the Zippered Mattress Cover.

The first thing you should do is pull one of the two mattresses over, so the side of it is touching the floor, when you do this, the two beds should form an L shape. This will make it easier for you to put the zippered mattress cover over the two mattresses.

Step 2. Take the Zippered Mattress Cover and Pull it Over the Ends of the Beds.

After you have turned one bed, you should take the zippered mattress cover and put it over the bed’s ends. After that, stretch out the other side of the zippered mattress cover and pull it over the second bed that is lying normally.

Using this method makes it easy for the zippered mattress cover to be pulled over since it doesn’t have to be stretched as much as it would need to be if both beds were on the floor.

Step 3. Push the Bed Back Into Normal Position.

After pulling the zippered mattress cover over all of the sides on both beds, you should push the first bed that you pulled over back in the normal position.

The zippered mattress cover will stretch out, and there shouldn’t be any problems using it. This method is relatively simple, and you will get your zippered mattress cover put on in no time if you follow these three simple steps.

How to keep a Trundle Bed from Separating Besides Using Zippered Mattresses Cover

The trundle bed sits on a collapsed-for-storage metal frame when it’s beneath the primary bed. After pulling it out, it pops up and stays in place so that it is the same height as the primary bed. Connecting the two gives you a single bed close in size to a king-sized bed. This can be especially helpful if you have couples who frequently visit. Make sure to also take a look at our article about mattress toppers vs mattress covers for more information too.

You can also use locking casters, rope, zip ties, or trundle bed conversion systems to keep trundle beds from separating.

To keep a trundle bed from separating, use some of the following techniques as alternatives to zippered trundle bed mattress covers:

Wheels
Rope
Cables
Conversion system

Below we’ll discuss these alternatives to zippered trundle bed mattress covers along with their pros and cons.

Use Locking Caster Wheels to Prevent Your Pop-up Trundle Bed from Separating

Adding locking caster wheels to your pop-up trundle bed will help prevent the mattresses from separating.

If you add locking casters to the trundle bed, once you move it into place and set it up the way you want, you can simply flip the lever on the casters to keep the bed from moving. The trundle bed already has wheels on it, making it easy to pull it out from under the primary bed, the one without wheels.

Adding locking caster wheels to your trundle bed will help keep it stable and safe when in use.

Some new models may come with locking casters, but if yours doesn’t, you can pick up locking casters or wheels from most home improvement stores. Take a sample wheel from the trundle bed with you to ensure you buy the right size.

Rope Can Be Used to Keep Your Pop-up Trundle Beds From Separating

Using rope can keep a pop-up trundle bed like this one from separating.

Even with locking wheels, you might want to go a step further and use a rope to tie the two beds together by the bottom legs that sit next to each other to ensure they don’t separate.

Adding additional support to the legs of your pop-up trundle bed (using rope) will help ensure additional stability when in use.

Cut four pieces of thin rope at least twelve inches long. Put the beds as close together as possible. Add two ties to each pair of legs to join the beds together. Tie a knot that won’t be too difficult to untie at the foot of the leg and closer to the bed frame. Repeat for each pair of legs. When you’re done, one leg from each bed should be tied together by a knot in two locations.

Use Plastic Cables To Add Stability To Your Pop-up Trundle Bed

Plastic cable ties that are usually used by police have more uses than just securing criminals. You can find these little things in home improvement stores, and they can be a lot of help when trying to keep beds from separating.

To add another level of stability to your pop-up trundle bed, secure these plastic cables around all of the legs of the bed.

Wrap the cable tie around a pair of legs, on both beds, and slip the tabbed end through the slot in the back of the head. Pull the tail of the cable tie through the head. If it doesn’t make a “zip” sound when pulled, reverse the direction you insert the tail. To remove, cut the table ties with a pair of scissors.

Use zip ties to keep a trundle bed from separating.

Conversion system

Trundle bed conversion kits are alternatives to zippered mattress covers

You can also purchase a kit that secures the mattresses together to keep the beds from separating. This kit contains a strap that wraps entirely around the mattresses to keep them from separating when secured by the buckle.

Using a conversion system with your pop-up trundle bed is another easy way to add stability to the bed and prevent the mattresses from separating when in use.

Before securing the two beds together, place the T-shaped piece of foam between the two beds, laying the long leg of the T between the two mattresses. The strap wraps around the mattresses and over the piece of foam to make the beds one single king-sized bed.
