Benefits of A Jack Knife Sofa

The best part is you can turn the sofa into a bed easily. You just need to pull down the seat and then the sofa will turn into a flat surface for sleeping. 

Depending on how big your rig is, you may be sleeping on it yourself, or just want the space for extra guests.

Both the sofa & bed are perfect in size to use in a RV.

Size of a Jack Knife Sofa

The size of a jack knife sofa depends on your RV size. 

If you own large RV or fifth wheel camper, then you can choose a big jack knife sofa. But if you have a smaller RV, then you should choose a small size jack knife sofa to fit the space. 

Most Jackknife sofas range from 68-72 inches in length with a depth of about 26-28 inches (when folded).  

The main area you have to consider is when a jack knife sofa is in bed mode. 

Because in bed form, it takes a lot of space. 

If you’re wondering what size sheet fits a jackknife sofa, it will vary with the furniture itself, but you’ll most likely be able to find home bed sheets that will fit.

That’s because the different bed sizes include twin, queen, full, and king.

You can choose one depending on your RV size. Just make sure whatever size you choose, it will fit in your RV.  Of course, that’s one of the most important things!

What Makes A Jack Knife Sofa Uncomfortable? 

Though the jack knife sofa is very convenient, some people find them uncomfortable to sleep on. 

Here are reasons that contribute to making a jack knife sofa uncomfortable:

• It’s surface is too hard to sleep on
• The cushion gap between the back and the seat makes it very uncomfortable when the jack knife sofa is in bed form
• Since the jack knife sofa is designed for space saving and versatility, comfort is not the first priority
• Jack knife sofas made from leather or leatherette is especially uncomfortable for sleeping
• If the metal frame (usually a steel frame) is not supported when extended, the sleeping surface can bow 
• It does not include a mattress to sleep on.

So, how do you make your RV sofa bed more comfortable for sleeping? 

The first step is to unfold it. 

Then, you’ll want to use some creativity. 

Let’s have a deeper look at how to make a jackknife sofa comfortable, below.

7 Creative Ways to Make a Jack Knife Sofa Comfortable in an RV

While a jack knife sofa is a great piece of furniture for your RV, there’s no denying that sometimes it feels uncomfortable while sleeping. 

But, no worries. The good news is, you can take these steps toward getting a better rest on your new sofa. 

Here are some creative methods to make your jack knife sofa comfortable in a RV. 

1. Use A Folded Quilt or Comforter

You can make a jack knife sofa comfortable quite simply by using a quilt or comforter to enhance the cushioning of the sofa. 

You just have to spread it over the jack knife sofa to soften that hard surface. (You’ll want to have some kind of mattress cover anyway to protect the sofa bed.)

Usually a quilt has three layers of fabrics and sometimes wool, and comforters can be very fluffy! So make this your first option.

So if you fold a large quilt or home comforter over your jackknife sofa, you will get more layers beneath you while sleeping. 

That should be thick enough for better sleeping comfort, so it’s the first thing you should try.

2. Get A Mattress Topper

You can also use a mattress topper to make your jack knife sofa surface more comfortable. 

They are thick, usually around 2-3 inches and are made of a layer of high-density foam or memory foam. 

For the most comfortable situation, make sure the mattress topper is the same size of your sofa.

3. Top With An Egg Crate Foam Pad

An egg crate foam pad is one of the best options for a jack-knife sofa. 

It is very soft and the egg shaped bumps make it more breathable. 

As with any topper, you have to consider the size of the egg crate foam pad and how it will fit on your jack knife sofa before you buy it. Ideally, it should be the same size as the sofa. 

In some cases, you can cut them to size, but it’s always better to try for a good fit to begin with. 

Likewise, you can look to a memory foam mattress or memory foam topper to make your jack knife couch a more comfortable sleeping surface.

4. Pool Noodles to the Rescue!

This idea is an especially creative solution, since you’ll be using pool noodles. 

When you turn the sofa into a bed, you will find it creates a gap between the seat cushion and the back cushion. 

This gap is the main reason it’s so uncomfortable while sleeping. 

So, you need to fill up the gaps with–you guessed it–pool noodles to level it off. Believe it or not, they make an excellent crack filler!

5. Top with an Air Mattress

If the idea of sleeping on pool noodles doesn’t sound much better, you can also layer a mattress topper or air mattress on top. 

The pool noodles will still fill in the gap making the overall sleeping experience better, but some air mattresses are so high, you won’t even need to fill in the gap. 

Either way, when you top your jackknife sofa with an air mattress, you’ll get a fabulous, comfortable night of sleep. It makes a huge difference in making your jackknife sofa bed more comfortable.

According to RV Inspiration, RV Owner Brandy Tidwell found that a futon mattress can be a good fit as a topper for your jackknife bed, too!

6. Make Your Own Sofa Pad

You can make your jack knife sofa more comfortable by making your own sofa pad. 

Then, you can customize it according to your needs. 

This is especially useful if you can’t find the right size, or you want the sofa pad to be a certain thickness or match your decor.

To make a sofa pad you will need:

• Measuring tape
• Thread
• Wool or Cotton Batting
• Cotton fabric 
• Scissors

First, you’ll have to cut the cotton fabric into two pieces that match the size of your sofa bed. 

Then, with the fabric design (if any) facing each other, sew three sides of the fabric together and leave one side unstitched. This will create an envelope, of sorts.  

Next, fill the envelope with wool or cotton batting to the desired thickness. 

Finally, stitch the open side to seal it up.

Now, you can spread the pad over the sofa bed for a comfortable night’s sleep. 

This will make a great addition to your RV furniture, and it gives you the chance to choose your own color options or use different colors to personalize your sofa pad.

It’s also an excellent choice for RV owners who want to stay within an affordable price range.

7. Use A Self Inflating Air Pad

Self inflating air pads are arguably the best way to make your jack knife sofa comfortable. 

These pads can import the air in automatically & make you feel comfortable when you are on the jack knife sofa. 

You can also release the air from the pad and fold it up when you don’t want to use it. That way, it doesn’t take up much space. This makes it a really good option to improve an uncomfortable couch.

What can I replace my stock jack knife sofa with?

Some people swap out a jackknife sofa for a wall-hugger recliner. This type of reclining chair, sometimes called a “wall away recliner” or “base of the wall hugger recliner,” needs only 4 to 5 inches of space from the wall to fully recline. It’s a great space-saving option when you swap out your jack knife sofa.

The main difference is, you can’t hide the chair away to make more space when you’re done sleeping.
