Review of La-Z-Boy’s Sofa Bed Mattress Selection

Est. Reading Time: 7 Mins

Sofa beds are a versatile piece of furniture offering a comfortable place for overnight guests. 

Sofa beds have always been popular, but believe it or not, sofa beds are on the rise! In fact, Magaly del Castillo, an interior designer at La-Z-Boy Cyrville, mentions that there has been an upward trend in people sleeping in their sofa beds during the summer when the weather is nice. 

“Some people have even chosen to place their sofa beds in their home offices or sunrooms,” she says.

Moreover, sleeper sofas are a great choice for anyone looking to change their living room or basement into a temporary guest room. With this being said, not all sofa beds are created equal. The comfort of a sofa bed can vary depending on the size, quality of construction, and type of mattress. 

At La-Z-Boy, we have several different sofa beds to choose from, which can be customized through various mattress options. This article will review the La-Z-Boy sofa bed mattress selection and outline how they differ from one another. 

After reading, you will better understand which mattress is best for your La-Z-Boy sofa bed.

Sofa Bed Mattress Selection: Unique Features

All La-Z-Boy upholstery furniture is customizable, including sofa beds! With this, La-Z-Boy has 3 different sofa bed mattress selections, each with their unique features and cost, which we will get into later. 

*It is important to note that La-Z-Boy does not manufacture our mattresses but gets them from other manufacturers.

Supreme Comfort

Supreme Comfort Sofa MattressFirst on our list is the Supreme Comfort Mattress, which is the most standard option at La-Z-Boy. This means if you were to purchase a sofa bed without requesting an air mattress or firmer mattress upgrade, you would be getting this mattress.

These sleeper sofa mattresses offer an extra layer of padding that provides cozy and, you guessed it, supreme comfort! 

Moreover, this mattress selection also comes with a high-quality innerspring system underneath the foam padding. The innerspring system is designed to conform to the body and offer added support for optimal sleeping comfort. 

The Supreme Comfort quilted innerspring mattress has a 5.5” thickness.

Slumber Air

Slumber Air Sofa MattressNext, the Slumber Air Mattress is perfect for putting any restless sleeper to sleep, according to Magaly. This mattress selection is considered an upgrade and will increase the cost of your sofa bed selection.

This mattress also comes with a 4” innerspring base, which softly contours to your every curve and supports you from head to toe. The inflatable cushion can be as thick as 6”.


New call-to-action


Simply use the hand-held air pump to inflate the mattress to whatever size you wish to snooze in. You can adjust the inflation to be as firm or as soft as you choose. The power is in your hands!

“The access for the pump can be easily located on the top right of the mattress, and it also has a cover, so you don't feel it when you sleep,” says Magaly.

Firm Mattress

Finally, the Firm Mattress is the newest addition to La-Z-Boy’s sofa bed mattress selection. Similar to the Slumber Air Mattress, this mattress selection is also considered an upgrade and will increase the cost of your sofa bed selection.

This mattress option includes a high-resiliency memory foam base that provides great comfort while reducing pressure points. The memory foam on this firm mattress also evenly distributes support for deeper relaxation. 

Finally, the enhanced durability of the mattress helps retain shape and quality better than many traditional foam mattresses.

Magaly even says that this mattress is “like laying down on a cloud.”


Sizes & Dimensions

The size and shape of your sofa bed mattress depend on the sofa bed that you select. At La-Z-Boy, we have 3 different sofa bed sizes, which will indicate the mattress size.

The best way to determine which size is right for you is by measuring your space.

Twin Sleeper Chair

Twin Sleeper ChairA Twin Sleeper Chair is the smallest sleeper option with the smallest pull-out mattress. As the name suggests, a Twin Sleeper Chair is a chair that can pull out into a twin-sized bed that can sleep one person.  

Magaly also says you may be able to squeeze one adult and a small child if you wanted to, but it is more recommended for one person.

The specific size of the twin sleeper chair depends on the specific furniture frame. Still, Magaly says the average width of a twin sleeper chair is 39”. The twin sized mattress has the following dimensions:

Twin Mattress Dimensions

71.5” L x 32” W x 5.5” H

Recommended Twin Sheet Size: 66” x 96” (Approx.)


Full Sleeper Sofa

Full Sleeper SofaFull Sleeper Sofas are much bigger than twin sleeper chairs because they can fit two people instead of one. This furniture item is right for you if you want something to sleep two people in a smaller space.

Magaly says the average width of a full sleeper sofa is 54”. These sleeper sofas feature a full-sized mattress with the following dimensions: 

Full Mattress Dimensions

71.5” L x 52” W x 5.5” H

Recommended Twin Sheet Size: 104” x 81” (Approx.)

Queen Sleeper Sofa

Queen Sleeper Sofa“Although there is room for two people on the full-sized mattress,” Magaly mentions, “you might feel a little snug if you move around too much in your sleep.”

If that’s the case, you might feel more comfortable sleeping on the Queen Sleeper Sofa. This is the biggest mattress size that La-Z-Boy has to offer

Magaly says the average width of a queen sleeper sofa is 60”. The queen mattress has the following dimensions:

Queen Mattress Dimensions

71.5” L x 60” W x 5.5” H

Recommended Twin Sheet Size: 110” x 90” (Approx.)


Sectional Modular Options

Sectional Sleeper Along with our sleeper sofa options at La-Z-Boy, customers can add any of our mattress selections onto a sectional. 

It is important to note that sleeper sofa modular pieces are not offered with every sectional at La-Z-Boy, only a select few. Further, the mattress size will depend on the sectional modular pieces.

Keep this in mind as you select a furniture frame and ensure that the style you like has a sleeper option and the mattress size you are looking for.  

Magaly points out the Collins Sectional as a great example of a La-Z-Boy sectional with a Full Sleeper Sofa module option. 


In terms of cost, Magaly states that a La-Z-Boy sleeper sofa is considered an upgrade and will always be more expensive than a regular sofa.”

With that being said, two main factors will indicate the cost of a sleeper sofa at La-Z-Boy: the size of the frame and the type of mattress.

Generally speaking, the larger the frame, the more expensive your sofa bed will be.

Each sleeper furniture product is covered by La-Z-Boy’s Limited Lifetime Warranty, including the mattress. This warranty covers any noticeable defects or physical flaws that cause the foam materials in the mattress to split in half. 

The warranty also covers the repair or replacement of the frame, spring systems, and mechanism, given that they are quality-crafted and built for long-lasting comfort.

While still quality-crafted, other aspects of the product, such as fabrics, leather, cushion, and mattress are not meant to last a lifetime. However, these parts are still covered by the La-Z-Boy Manufacturer’s Warranty for a given time.

To further protect your purchase, La-Z-Boy offers an extended warranty plan at an additional cost.


Which Sofa Bed Mattress is Right For You?

Now that you know everything you need to know about La-Z-Boy’s sofa bed mattress selection, the question remains, which mattress option is right for you? 

To help answer this question, you should consider your budget, your comfort preferences, who will be using this sofa bed, and where the sofa bed will live in your home. 


As mentioned before, La-Z-Boy sofa bed mattresses can be expensive, and each mattress option comes at a different cost. 

If you are shopping on a budget, Magaly recommends purchasing the Supreme Comfort mattress since it is the least expensive option.

In contrast, if quality comfort is a priority to you and you are willing to spend, the Firm mattress might offer the support you are looking for. 

And on the other other hand, if you are trying to find a balance between cost and comfort, you can control the level of firmness with the less expensive Slumber Air mattress.

When selecting the size of your mattress, you will want to think about who will be using your sofa bed and the space you will put it in. 

A Twin Sleeper Chair should suffice if this sofa bed is for one guest in a small space. Alternatively, if you have lots of space and find yourself having multiple overnight guests, it might be better to get a full or a queen sleeper sofa.

As you access your space, check out our articles on Smaller Space Furniture or Open Concept Living.

With all of these options to choose from, Magaly says that sofa bed options are meant to be a selfish choice. “I would choose what you would like to sleep on, because afterall, it is your sofa and you can choose to sleep on it, too.”

At La-Z-Boy, we realize that not everyone is perfect and that our furniture may have some problems. If you want to learn more about the Common Problems with our Sofa Beds, take a look at this article.
