    • 15 guage steel

    • more durable support system than just foam

    Quilt & Comfort Layers

    comfort layers inside Cape-6" mattress

    Quilt Layer

    • Custom quilting w/ integrated FR properties
    • .75" of medium, 1.5 density gel-infused padding
      • CertiPUR-US Certified
      • All USA made materials

    Comfort Layer

    • .75" of firm, 1.8 density padding
      • CertiPUR-US Certified
      • Made in USA

    What you'll notice:
    A simple, medium feel that is supportive and conforming. Gel-infused quilt padding will dissipate heat faster than regular padding. For a 6" thick mattress, this is about as good as it gets. Ideal for setups that require a thinner mattress.


    Odd/Custom Size Mattress Variance

    Due to coil barrel diameters, all custom/odd-size mattresses are subject to up to a 1" variance in each direction.

        • As skilled as our builders are, it is almost impossible to construct a spring mattress to the exact dimensions of all size combinations. Each coil spring has a predetermined diameter, therefore we are somewhat limited when it comes to the width and length of the mattress.  Since we cannot split a coil in half or thirds, we build the mattress to within a 1" variance of requested dimensions. 
        • In most cases our mattresses are very close to perfect. However, these restrictions do exist and it is completely normal to see your mattress slightly smaller or larger than ordered.
        • On the Cart page, there is a box where you can request the mattress to be made "slightly undersize" or "slightly oversize".

        Great mattress

        We needed a mattress for our RV spare room, it has odd dimensions. Custom mattress made one super comfy and got to us quickly 👍🏻

        Brenda W. (San Leandro, CA)
        Very nice

        My custom built mattress is wonderful! Very sturdy, and well made. Sleeping better since I've had it. Would definitely recommend to anyone looking for a mattress that needs to be custom made.

        Perfect Custom Mattress for our RV bunk!

        We ordered a Cape 6” custom-sized mattress to fit the upper bunk in our new RV trailer. The fit is perfect, and the mattress is high quality and very comfortable. Extremely pleased with our purchase!

        Travis C. (Wetumpka, AL)
        Highly recommend!

        The mattresses are a perfect fit. The service and quick turnaround were a life saver! Thank you.

        Best Custom Mattress EVER!!

        We needed one for our van we converted and it worked out super well. It's the perfect size.

        Larry W. (Sun City, AZ)
        2 Special size

        The two mattresses are great, I would prefer one to be firmer. We bought our old mattresses in Germany so I hope these have the same quality.

        Jeanne W. (Derwood, MD)
        Custom mattresses are great!

        We had such a hard time finding mattresses that would fit on our older built-in bunks until I discovered your company. My experience was excellent. The products are high quality, the process was easy and you delivered them so quickly. Thank you! We are very happy with the outcome.


        Ask a Question
        • What materials are your mattresses made of? Do they have polyurethane foam and fire retardants?

          Yes, all of our mattresses use a polyfoam padding layer. Some models just have it in the top quilting, others use it in the comfort layer. This is a 100% USA made foam and is CertiPUR-US Certified. The answer to your second question is yes, we are required by United States law to use a flame resistant material in all of our mattresses. Instead of using a spray chemical like some companies, we use a thin layer of silica based fabric that is sewn into the top cover and side borders. This is product is "inertly" flame retardant, which means it naturally smolders out any flame introduced to it. 

          I hope that answers your questions!

        • Can you feel the coils underneath the thin layers of foam?

          No, you shouldn't. Most individuals are suprised that there are actually springs inside. The Cape uses-fabric encased coils, which are quite different than traditional coil springs. Instead of being tied together by steel, these are linked with fabric. This allows for each coil to work independently and conform efficiently to the body. In fact, laying on just the coils alone with no padding is quite comfortable! At 6 inches thick, most people would expect something along the lines of a sofa mattress. This is quite different. The comfort and durability is well above average given the depth.

        • What should I place this mattress on?

          Correct support for a mattress can be provided by any of the following:  1.) A firm, relatively new boxspring. The surface of the boxspring should be completely flat across with no "bowing" in the middle. If the boxspring is more than 8 years old, it should be replaced.  2.) A platform style bed frame with a roll-out slat system. The gap in between each slat should be no more than 3". If the gap in between each slat is wider than 3", more slats should be added or a boxspring needs to be used.  3.) A solid platform surface. The surface should be sturdy and completely flat, free from impressions. Keep in mind that the entire mattress must be supported evenly from edge to edge. 4.) An adjustable bed. All mattresses on this website are designed to work with adjustable beds.
