Are Custom Mattresses Affordable?

Made In USA Bedding - Beloit Wisconsin
The answer is, yes!

Because we’re factory-direct, we cut out the middle man, which allows us to maintain our high-quality standards while keeping our costs down, passing the savings onto you by providing the best in value products.

We’re a 4th generation American mattress company. Our success as bedmakers comes from hard work, innovation, and adhering to the time-tested practices of handcrafting high-quality, all-natural fabric custom mattresses and toppers, one at a time since 1929.

Our #1 goal is to improve your quality of life by building you the best custom mattresses and toppers for a better night’s sleep.

Custom Mattress Types

We’ve been handcrafting all types of custom mattresses and custom mattress toppers in all shapes and sizes for decades.  Whether you need a new custom mattress size or custom mattress topper to place on a custom shaped cushion, we can help!

RV Mattress

RV Mattress

RV mattresses have been the #1 custom mattress type we’ve been privileged to support. If you need a particular RV mattress size, whether an RV queen or king mattress, RV bunk mattress or any custom RV mattress, we can help you.

We’re known for offering the best mattress for RV because every custom mattress is crafted by hand, one at a time, based on your specific RV mattress sizes.

While most every recreational vehicle has bed frames or some form of the sleeping surface, we understand that they are typically small, often have low profiles, and require mattresses with non-standard dimensions.

You can count on us to make whatever RV mattress size you need, and that we’ll make it with the best bedding ingredients on the market today. Your new RV mattress will be comfortable and long-lasting.

Boat Mattress

Boat Mattress

Boat mattresses are another popular request from our customers. Whether you’re cruising, yachting, or sailing, having comfortable beds and cushions brings your family and friends the best comfort and support.

We craft every custom marine mattress and topper with high-quality materials made for high moisture boat environments.

Most marine mattresses typically have thickness restraints. Standard marine beds are 5-inches to accommodate people weighing up to 200 pounds and 8-inches for up to 250 people without bottoming out. Whatever your weight or need, we can customize a mattress to your specific needs.

Our top-quality ticketing offers a non-flip design—a quilted damask cover for your sleeping side and a skid-resistant fabric to keep your mattress from shifting.

Futon Mattress

Futon Mattress

Futon mattresses are another popular choice. Is your futon mattress worn out? You’ll be glad to know we offer a range of futon mattresses handcrafted with a high-density foam core and natural cotton.

If you like that traditional futon feel yet have a durable mattress that lasts long-term, you’ll love our custom futon mattresses.

Are you looking for a more premium feel? We can include a strong coil innerspring (240-560 encased coils) coupled with bonded cotton, high-density foam, and natural cotton.

Our futon mattresses come with a full 10-year warranty.

Rollaway Mattress

Rollaway Mattress

A rollaway bed can be folded and rolled away into a closet. Rollaway mattresses are popular in hotels and motels when you need an extra sleeping surface.

Homeowners use them as a great alternative when they have company stay overnight in replace of the couch.

A standard rollaway bed often compares to a twin-size bed (38″x75″) and mainly supports one person. Most rollaway beds sold today can support up to a 400-pound person.

No matter your custom size need, we can make you a rollaway replacement mattress that will offer superb comfort to whoever sleeps on it.

Camper Mattress

Camper Mattress

A sister to the RV, camper mattresses have similar traits. Whether you have a fifth-wheel trailer, pop-up camper, or even a truck camper, we can make you a custom replacement camper mattress that brings you great comfort as you travel.

Because most camper mattresses have to be thin, we can make a low-profile mattress that packs the best in comfort and durability. Whether you prefer a bed or even a custom-made mattress topper, we can make any size, shape, and height to satisfy your specific camper needs.

Our camper mattresses and toppers are made of high-quality, high-density materials to allow high spots like your hips and shoulders a little more sink for best comfort.

Tent Mattress

Tent Mattress

Are you a camper that enjoys the comfort and feel of a mattress rather than the hard ground through a sleeping bag?   We recommend investing in a custom mattress topper to help you get the best sleep.

Why sleep on an air mattress that can often deflate in the heat of summer? Stop waking to a deflated mattress that leaked overnight.  A comfy mattress topper is reliable and easy to transport.  

Our mattress toppers can be conveniently rolled up and stored when not in use and lay flat on any surface to bring the comfort of home right into your tent.

And because we can build you a custom topper, we can make any size or shape mattress topper you desire.

Truck Mattress

Truck Mattress

We love truckers and know how important sleep is to them. We build every custom truck mattress with the driver in mind. We offer all-natural fabric materials that are healthy, breathable, hypoallergenic, and environmentally friendly.

Whether you sleep hot and want a cool feel or have a team driver and need to reduce motion transfer while driving, you’ll get the best rest by having us custom design a new truck mattress for your rig.

And because we can custom made any size and shape, we can make a truck mattress for any truck, whether a Mack, Freightliner, Peterbilt, International, Kenworth, Volvo, or other.

You’ll be glad to know that our truck mattresses are road-tough! We make them durable with comfortable pocketed springs designed to help keep your spine aligned and reduce pressure points.

Sofa Sleeper Mattress

Sofa Sleeper Mattress

A sofa sleeper mattress is an excellent piece of furniture that helps homeowners transform almost any room into that instant guest room. A sofa mattress conveniently pulls out and converts into a bed.

Sofa bed mattresses are typical in studio apartments. Homeowners and renters alike can bring more comfort to their sofa sleeper by replacing the mattress or even adding a mattress topper.

Most customers that we serve come to us saying their sofa mattress has become very uncomfortable or too thin to feel the metal pieces digging into their backs.

We can solve these common problems with a custom sofa sleeper mattress. The key to adding comfort for your guests is to replace your old sofa sleeper mattress with the same size replacement mattress made with quality bedding components.

Hospital Mattress

Hospital Mattress

One of the many types of custom mattresses we offer is hospital mattresses. We work with many home health care and social service organizations that rely on us to build vinyl “hospital-style” covered beds for the physical and mentally disabled.

A quality hospital mattress (others call them hospital cots) from The Beloit Mattress Company will be easy to sanitize for healthcare workers, comfortable for the patient, and durable to last many years.

We provide custom hospital mattresses, no size or shape, or material beyond our capability.

Murphy Bed Mattress

Murphy Bed mattress

Many consumers request murphy bed replacement mattresses. Murphy bed mattresses are typically thinner than a traditional mattress.

Murphy beds allow homeowners and renters alike to have more floor space. They are easy to access and offer a sleek design. But in addition to these great aesthetics, comfort is typically the most important factor when consumers search for a replacement mattress for their Murphy bed.

Murphy Wall Beds states that you can use any coil-spring mattress up to 10″ thick as a replacement Murphy bed mattress.

Murphy beds cause more strain on your mattress than traditional beds because of the constant motion of having to lift it away when not in use. Getting a quality replacement Murphy bed from The Beloit Mattress Company is a great choice.

Antique Mattress

Antique Mattress

Consumers and bed and breakfast business owners come to us for a custom-sized mattress for their antique beds.

We’re proud to specialize in mattresses for antique beds. We can handcraft a mattress to your exact width, length, and height. We can make any shape, including rounded corners, and even notch the corners around your antique bedposts.

Whether you have a wooden bed, rope bed, metal bed, Jenny Kind bed, plantation bed, or even spindle spool beds, we can help.

The key to ordering a custom antique mattress is making sure you measure precisely.

Custom Mattress Sizes

Big and Tall mattress
Need a specific custom mattress size?

We’ve made custom mattress sizes for tall people, heavy people, and everyone in between.  Our high-quality custom mattress sizes can solve many common issues.

  • Is your mattress too short?
  • Is your mattress not wide enough?
  • Is your mattress sagging?
  • Has your mattress lost all comfort?
  • Have no edge support?

Custom Bed Sheets

We’ve helped thousands of boat and RV owners with one common problem; they could not find custom size sheets and toppers to fit the precise angles of their mattresses and cushions alike. Keep in mind that most shapes aren’t symmetrical, nor straight as many bow on the arcs.

How To Measure For Custom Mattress.

It’s important we receive precise measurements no matter what the application, boat, RV, antique bed, etc.  

Couple measuring a mattress

While most mattresses are straight forward in measuring, pay particular attention when needing to replace a custom mattress or an antique bed.

  • Measure how long the inside of your bed is on both sides.
  • Measure how wide the bed is at the head, in the middle, and at the end.  We recommend 3-4 different spots.
  • Measure how wide the bed is at the head and foot of your bed.
  • Measure how high you want your bed to finish off the floor.  Because it is common for an antique bed frame to be 15″ off the floor (the average frame today is 7″) – you’ll want to measure from the floor to the bottom slat of the box spring.

You may want a “low profile box spring” and even a “shorter mattress” to easily climb into bed without needing a step stool.

If you have any doubts about measuring, you’ll have the ability to upload photos when you request a quote.
