Is sleeping on memory foam hot?
The gel swirl technology of our standard size mattresses is a temperature neutral environment. This means that you will slip into a cool bed. Other more expensive cooling mattresses may only diffuse up to three degrees lower than this.

How Do I Create a Template for a Custom Mattress?
Replacement Mattress offers RV, sofa bed, marine, and truck mattresses in custom shapes and sizes to fit the needs of any space. If you’re placing an order with a custom template, follow these five easy steps for an accurate outline: 1. Patch together paper into one large sheet that slightly hangs over all sides of the platform on which you will be using your replacement mattress. We recommend using flooring paper from a home improvement store, gift wrapping paper, or any other paper that can be easily put together to cover the entirety of the platform. 2. Press the paper over the sides as you trace the outline of the platform. 3. After your outline is traced, write “TOP” on the paper to indicate the top side of the mattress (the side you will sleep on) before removing the template from the platform. 4. Once you have removed your outline, write the following information under where you wrote “TOP”
  • Your name
  • Shipping address
  • Billing address (if different from shipping address)
  • Contact phone number
  • Email
5. Carefully fold up the template and put it in an envelope, or roll and put into a tube, and send to: Replacement Mattress c/o Walt’s Sleep Shop 721 Hwy 35 Middletown, NJ 07748 If you have any questions or need any assistance creating your custom mattress template, call us at 888-889-2812 and we will walk you through the process.

Choosing Your Replacement Mattress

Which RV, Marine or Truck Mattress model do I choose?
We put our premium models as the first option on the left. If budget isn’t a factor go with that model for the type of mattress you need.
How do the sofa bed mattresses from Replacement Mattress differ from the competition?
Every one of our mattresses is designed for ultimate quality, comfort, and durability, and can be customized to fit your unique needs. The primary feature that sets our mattresses apart is the solid foam core. We find that this provides the best support in a 4” depth and keeps the mattress from bottoming out. Additionally, we use a “Sewn Tape Edge” construction for durability. This means we take the time to tape the edge and sew the cover on. As a result, our mattresses—sofa bed mattresses in particular—can better withstand the folding and unfolding of the sofa bed mechanism compared to the cheaper “zip-on” cover used by most competition.

How does foam density affect the quality of my sofa bed mattress?
The higher the quality of foam used in your sofa bed, marine, truck, or RV mattress, the more comfortable it will be and the longer it will remain at that original level of comfort. The quality of mattress foam is determined by its:
  • Density—pounds per cubic foot
  • Indentation Force Deflection (IDF)—measure of firmness or how many pounds of force are required to make an indent in the foam
  • Thickness
  • Durability
  • Flex Fatigue
  • Compression Set
Generally, the higher the density of foam, the more supportive the mattress will be. To learn more about foam density and the other factors that determine foam quality, visit our All About Foam page for more detailed information.
What is the difference between a foam and a spring sofa bed mattress?
Foam mattresses compress based on your body weight. The foam conforms to your body to deliver greater, more individualized support while you sleep. Foam mattresses are usually softer than spring mattresses and ideal for relieving pressure and isolating motion. Spring or innerspring mattresses are made with metal springs or coils. The spaces between the coils facilitate better airflow than a foam mattress, which generally makes spring mattresses a better choice for those who sleep hot. Spring mattresses also offer more support and firmness compared to foam. As a result, they’re typically recommended for heavier individuals and individuals with back problems. For more information about the differences between foam and spring mattresses, click here.
What should I take into consideration when choosing a sofa bed mattress?
Choosing a sofa bed mattress that will provide you with the lasting comfort and support you need comes down to a few different factors: size, type of material, thickness, and more. Our experts put together a Sofa Bed Mattress Buying Guide with all the information you need to make the best decision.
Will I feel the bar with your sofa bed mattress?
Believe it or not, this is the number one question asked of us. Thankfully, we can always assure our customers that our products excel when it comes to quality and comfort. It is very unlikely that you will feel the bar of our sofa bed mattresses. There are, however, a few things to keep in mind when it comes to choosing a sofa bed mattress:
  • The most important factor in choosing a comfortable and supportive mattress is the weight of the sleeper. Our sofa bed mattresses are designed for the majority of people, so about 90 % of sleepers will have no problem with any of our models. Extremely heavy sleepers, however, may deflect the sofa mattress beyond its ability to fully cushion the bar.
  • The denser the foam in a sofa bed mattress, the more comfortable it will be. If you’re worried about feeling the bar, consider opting for our Platinum Sofa Bed Mattress.

Ordering Your Replacement Mattress

Is it safe to buy a replacement mattress online?
People are sometimes wary when it comes to ordering a mattress online, but there are actually quite a few advantages to purchasing a sofa bed, RV, marine, or truck mattress from an online store:
  • Shape & Size—Replacement mattresses are available in a more diverse range of shapes and sizes online compared to what you will find in a store. At Replacement Mattress, we offer a variety of stock sizes as well as custom sizes and shapes.
    • Quality—Each of our replacement mattress types come in many different quality grades. We sell only top-quality mattresses on this website. Stores usually carry only average quality when it comes to sofa bed, RV, marine, and truck mattress, if they have any at all.
  • Price—Boat, trailer, truck sleeper, and sofa bed mattresses will cost you about 60% more in stores, compared to when you order directly from the factory.
  • Availability—If we do not have what you want, we can easily custom make it to order and have it delivered to you in about a week.
  • Security—We use PayPal, which is about as secure as it gets online and in-store. Buying on the phone or even in a store means that you will be giving your credit card information to a stranger.

We make radius corners, large radius ends, as well as mattresses which require a combination of cut and radius corners. Here are some examples of shapes we can create: In most cases, we will request that you create a template of your mattress platform, which allows us to customize a mattress exactly to the specifications you need.
