The number one question asked of us is: “Will I feel the bar with your sofa bed mattress?”

The answer is: “Not likely”. There are some exceptions:

  • The most important factor is the weight of the sleeper. Our sofa bed mattresses are designed for the majority of people. About 90 % of sleepers will have no problem with either of our models. Obviously, extremely heavy sleepers may deflect the sofa mattress beyond its ability to fully cushion the bar.
  • Another issue is related to the foam density of the sofa bed mattress. The denser the foam, the more forgiving the mattress. If you think it might be a problem, we urge you to consider our Platinum sofa mattress.
  • No other sofa bed mattress can beat our quality in any respect. With regards to not feeling the bar, our products excel.
What should I take into consideration when buying a sofa mattress?

How do our mattresses differ from the competition?

We use solid core foam in all of our mattresses. 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. We feel that some things are better done the old-fashioned way. For us and our customers, it’s worth the time it takes to tape edge and sew the cover on, as it stands up better to folding and unfolding of the sofa bed mechanism. In our eyes, this is far superior to a cheaper “zip-on” cover which is favored by our competition.

Do you manufacture other RV and Boat mattress shapes not listed on your site?

Yes… 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 that will fit your platform.  (Click Here to see how to make a custom template.)

How long will it take to ship my new sofa, marine, truck or RV mattress?

Common size mattresses can be shipped within one day if an order is received by noon, Eastern Time (full and queen sofa bed mattresses can be shipped within one day). A custom mattress is typically shipped within 7-10 days of being ordered.

Can I cancel my order once it has been shipped?

You may cancel your order any time prior to delivery. However please note that, once shipped, you are responsible for the original freight cost we charged, and for the return shipping cost.

All About Foam

The quality of that foam is the limiting factor in:

    • How comfortable your sofa mattress, RV mattress, marine mattress and truck mattress will be.
    • How long your replacement mattress will remain comfortable to sleep on.

Foam vs Spring

Ordinary mattresses are quite thick. They have room for high quality springs to float before they compress fully. High quality springs have more coils. (See Image at Left).

Sofa bed mattresses are less than half as thick as a good standard mattress. There isn’t a lot of room for springs to float before they fully compress. Top quality springs are out of the question. (See Image at Right).

5 Easy Steps to Create a Custom Template
  1. Patch together paper so that you have one sheet that slightly hangs over the platform on all sides. (You can tape together brown paper for floors from Home Depot, or gift wrapping paper, whatever works to create one sheet of paper large enough to cover the platform.)
  2. Press the paper over the sides as you trace the outline of the platform
  3. Before removing the template of the platform, write TOP on the paper to indicate the top side of the mattress, which is the side you will sleep on.
  4. Under the word TOP include the following info on the template:
    • 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 it and put it in a tube and send to:
