Every custom mattress topper starts with the same question: what does your sleep space need? In this video, Ryan explains how custom toppers can be made for RV mattresses, boat beds, antique beds, odd sizes, special shapes, and hard-to-fit spaces.

You will see how our team thinks through size, shape, material, and comfort so your topper fits properly and feels right once it arrives.

CertiPUR Basic Mattress Topper - On RV Twin Bunk Beds

Focusing on RV toppers, we are the authoritative source for unmatched comfort during your travels. Every RV topper is diligently handcrafted to precise measurements for an RV queen, king, or custom bunk size.

Whether you possess an RV or a travel trailer, our specialized RV topper solutions ensure a sleep experience that rejuvenates you for the journey ahead.

 

Boat Mattress

For fans of marine travel, a restful sleep surface is not just a luxury—it’s essential. Our custom boat toppers are engineered to handle high-humidity conditions while offering unparalleled comfort and support. Recognizing the common thickness limitations on marine sleeping surfaces—standard thicknesses typically range from 2 to 4 inches—we deliver custom-made topper solutions designed to prevent “bottoming out” without adding excessive height. These boat mattress toppers are adorned with premium fabric, feature a single-sided quilted design optimized for comfort, and incorporate anti-slip material to ensure stability during nautical adventures.

We aim to provide a sleep surface that caters to individual preferences by utilizing all-natural, breathable, hypoallergenic, and eco-friendly materials. Whether you’re concerned about staying cool during sleep or need to minimize motion transfer when sharing the driving responsibilities, a custom-designed truck topper from us will enhance your rest on the road. Our toppers are adaptable to any truck make and model, whether a Mack, Freightliner, Peterbilt, International, Kenworth, Volvo or any other. Moreover, our truck toppers are built to last, featuring durable pocket spring mattress designed to align your spine and alleviate pressure points, ensuring you’re well-rested for the long haul.

 

Custom Family Bed

For families seeking enhanced comfort, more room, and quality time, our Custom Family Toppers are a transformative addition to your sleep setup. Why confine yourselves to standard topper sizes when you can opt for a custom-fitted experience designed for your family’s diverse needs? Our oversized family toppers come in three unique dimensions: 108×80 (akin to two Full XLs), 120×80 (similar to two Queens), and 144×84 (the size of two California Kings). Each family topper is handcrafted with attention to detail, and we also offer compatible frames and foundations for a cohesive and supportive sleeping environment. Every element is carefully made from high-quality materials to suit various family members’ sleep preferences and body types. Opting for a Custom Family Topper is ideal for large families, those who co-sleep with young children, or anyone who enjoys spacious comfort.

Rollaway Mattress

Mattress toppers for rollaway guest beds provide an ultimate convenience and space optimization solution. While these folding toppers are frequently found in hotels and motels, they are also becoming increasingly popular among homeowners who need a comfortable extra sleeping surface for guests. Standard rollaway toppers usually align with the size of a twin bed, measuring 38″ x 75″, and are ideal for a single sleeper. We specialize in custom toppers designed to fit your rollaway beds perfectly. Regardless of the specific dimensions you need, our handcrafted toppers aim to deliver unmatched comfort to your guests.

 

Camper Mattress

Are you a fan of outdoor activities but miss the supportive comfort of your mattress when camping? Elevate your outdoor experience with a custom topper designed explicitly for you.

Sofa Sleeper Mattress

Upgrade your sofa bed and make any room an instant haven for guests. Sofa sleepers are convenient, but they often feature mattresses that leave much to be desired in terms of comfort, causing restless nights for your visitors. We have the ideal solution if you’re dealing with a flimsy, worn-out sofa sleeper mattress that fails to provide adequate support. Our toppers for sofa beds are designed to transform your dual-purpose furniture into a sanctuary of comfort. Whether working with limited space in a studio apartment or simply looking to enhance your living area, we’ll help you elevate the sleep experience for you and your guests.

 

College Dorm Mattress Topper

A mattress topper is an invaluable addition to any college dorm room. Unlike standard toppers, a custom option can be tailored to your comfort needs, ensuring optimal sleep quality. This is crucial for students who face academic pressures and need restful sleep for peak performance. Custom toppers can also be designed to fit non-standard dormitory bed sizes, providing a seamless fit that stays in place. Moreover, they offer a hygienic barrier between you and a previously used mattress, which is often the case in dorm rooms. With options to choose hypoallergenic materials or offer temperature regulation, a topper becomes more than just a comfort accessory; it’s a personalized sleep solution.  Or consider a standard size by shipping our Dorm Topper made explicitly for college dorm rooms.

Murphy Bed mattress

Murphy beds are an intelligent way to maximize space, especially in smaller living areas. However, the mattresses that typically come with them often fall short of providing comfort. If you’re looking for a balance between sleek design and restful sleep, consider adding a mattress topper designed for Murphy beds.  Made from high-quality materials, our toppers are engineered to stand up to the specific strains posed by the Murphy bed’s lifting mechanism, ensuring you a comfortable and restful sleep experience.

 

Antique Mattress

When it comes to antique beds, each one is a distinct work of art that often doesn’t match standard mattress dimensions. That’s where we step in. We craft custom-size toppers that rejuvenate antique beds, catering to individual homeowners and bed and breakfast businesses. Our expertise spans various antique bed styles, including wooden and rope beds, metal frames, Jenny Lind, plantation, and spindle spool beds.

Yes. Custom toppers are often used for RVs, boats, campers, truck sleepers, sofa beds, bunks, rollaways, antique beds, and other hard-to-fit sleep spaces.

Use a mattress protector and spot clean as needed. Avoid machine washing or drying the topper unless the care instructions for your specific topper say otherwise.

Warranty depends on the topper material. HyPURGel®, Natural Latex, and Premium Quilted toppers include a 5-year replacement warranty. CertiPUR Basic includes a 2-year replacement warranty.

Most custom toppers are 2 or 3 inches thick, depending on the material and comfort level you choose. A topper should improve comfort, not replace a worn-out mattress.

Choose HyPURGel® for cooler softness, natural latex for responsive comfort, premium quilted for a pillow-top feel, or CertiPUR Basic for a simple comfort upgrade.

Measure the length, width, thickness preference, and any special corners or shape details. For unusual shapes, include a drawing, template, or photos so our team can confirm the best fit.

No. A topper can improve surface comfort, but it will not fix a mattress that is sagging, broken down, or no longer supportive. In that case, a replacement mattress may be better.
