Custom Foam for RV Cushions, Dinettes & Sleeping Areas
Factory RV cushions use cheap, thin foam that goes flat fast — and replacements are nearly impossible to find in the odd sizes and irregular shapes that RVs demand. We cut premium foam to your exact measurements, compress it for shipping, and deliver it straight to your door.
Why RV Cushion Replacement is So Difficult
Factory foam is rock-bottom quality
RV manufacturers cut costs on foam first. The foam that ships in most new RVs is low-density, low-resilience material that compresses flat within a year or two of regular use.
Exact replacements do not exist
RV cushion sizes are not standardized. Each manufacturer uses different dimensions, and those dimensions change model year to model year. You cannot order a stock replacement — you need a custom cut.
Odd shapes complicate everything
RV interiors pack seating into every corner. That means T-shapes for wrap-around dinettes, L-shapes for corner benches, and tapered cuts for cab-over sleeping areas. Local foam shops struggle with these.
The Right Foam for Every RV Application
We keep it simple with two premium options chosen specifically because they cover every real RV use case — nothing cheap, nothing that will disappoint after a season of use.
Indoor HR Foam
2.8 lb High-Resiliency — CertiPUR-US Certified
The correct choice for any foam that lives inside your RV. High-resiliency foam bounces back after every use — it does not flatten and stay flat the way cheap foam does. Made with an advanced cold-cure process that actually improves with break-in.
- RV dinette seat and back cushions
- Jackknife sofa seating and sleeping
- Sleeping berths and rear queen beds
- Cab-over sleeping area foam
- Driver and passenger seat padding
Outdoor Dry Fast Foam
Reticulated Open-Cell — Water Drains Instantly
Designed for any cushion exposed to rain, moisture, or the outdoors. The open-cell reticulated structure lets water pass straight through rather than absorbing it — so cushions dry in minutes instead of staying wet for days and growing mold.
- Awning-area lounge and chair cushions
- Exterior storage bay seat cushions
- Slide-out patio cushions
- Wet-bath seat padding
- Any foam in high-humidity or outdoor zones
Every Cushion in Your RV, Replaced
From the front cab to the rear bedroom, we cut foam for every seating and sleeping surface in travel trailers, motorhomes, fifth wheels, Class B vans, and campervans.
RV Dinette Cushions
The most common RV foam replacement. We cut T-shapes and L-shapes that match factory dinette layouts exactly.
Jackknife Sofa Foam
Jackknife sofas take abuse daily. Our 2.8 lb HR foam holds its shape through thousands of fold-open and fold-close cycles.
Sleeping Berth Foam
Upper and lower berths, rear queen beds, and fold-out sleeping areas. We cut to every size travel trailers and motorhomes use.
Cab-Over Bed Foam
The tapered, wedge-shaped cab-over sleeping area requires precise custom cuts. We handle the odd angles.
Slide-Out Dinette Pads
Slide-out dinettes come in non-standard sizes. We cut to your traced dimensions so the fit is always perfect.
Driver & Passenger Seat Padding
Add comfort to worn cab seats with a custom-cut foam pad sized to your seat base.
Why T-Shapes and L-Shapes Are Standard in RV Dinettes
RV manufacturers maximize every square inch of interior space. Dinettes wrap around corners to fit more seating into a compact floor plan — which means the cushions follow that same geometry.
A typical wrap-around dinette uses two or three separate cushion pieces that meet at a corner. The seat cushions are often T-shaped or L-shaped, with one portion running along the back wall and another turning the corner. Standard rectangular cuts will not work.
Our online configurator handles T-shapes and L-shapes natively. Select your shape, enter the dimensions for each leg, and we will precision-cut the exact profile you need. For unusually complex layouts, send us a traced paper template or a photo with measurements marked and we will cut from that.
T-Shape Dinette Cushion
Common for straight bench dinettes with a back ledge section — one continuous foam piece that covers both the seat and the return.
L-Shape Corner Cushion
Used in corner-wrap dinettes where seating turns a 90-degree angle — the single most common dinette shape in Class A motorhomes and fifth wheels.
Compressed Shipping That Fits Through Your RV Door
Getting a large foam piece through a narrow RV door is a genuine problem. We solve it by vacuum-compressing every order before it ships. The packaging collapses the foam to a fraction of its expanded size — small enough to carry through a standard 24-inch RV door without any maneuvering.
Once inside, cut the packaging open and let the foam breathe. It fully expands to its final dimensions within 24 to 48 hours. No assembly, no tools, no hassle.
Vacuum-compressed for shipping
Reduces package size dramatically so it fits through any RV door.
Free shipping over $199
Most RV cushion sets qualify. Ships in 3–5 business days after cutting.
Fully expands in 24–48 hours
Just open the package inside your RV and let it expand to size.
30-day satisfaction guarantee
If we cut it wrong, we re-cut it at no charge.
Real RV renovation. Real results.

RV Foam Questions Answered
Can you cut foam for an RV dinette?
Yes — we specialize in cutting foam for RV dinettes, including the T-shapes and L-shapes that are standard in most travel trailer and motorhome dinette configurations. Just select your shape in our online configurator, enter your exact measurements, and we will precision-cut your foam to fit. If your dinette has an unusual shape, contact us and we can work from a traced template or detailed dimensions.
What thickness is right for RV sleeping areas?
For RV sleeping berths, cab-over beds, and fold-out sleeping areas, we recommend 4 to 5 inches of our indoor HR foam. This provides comfortable, supportive sleep without adding unnecessary bulk in a compact RV space. For cushions that do double duty as both seating and sleeping (like jackknife sofas), 4 inches is the sweet spot — firm enough for daytime seating, comfortable enough for overnight use.
How do I measure my RV cushions for replacement?
The most accurate method is to remove the old foam insert from its cover and measure the foam directly on a flat surface. Measure the full length, width, and thickness. For T-shaped and L-shaped dinette cushions, measure each leg of the shape separately. If the old foam is too deteriorated to measure accurately, measure the inside dimensions of the cushion cover instead. Write everything down and round to the nearest quarter inch — that is the precision we cut to.
Will the foam fit through a narrow RV door?
Yes. We vacuum-compress all foam for shipping, which reduces the package to a fraction of its original size. The compressed package fits through standard RV entry doors (typically 24 to 28 inches wide) with ease. Once inside, simply open the packaging and allow 24 to 48 hours for the foam to fully expand to its final dimensions. This compression method also makes it easy to position the foam in tight spaces before it fully expands.
Which foam is better for RV use — indoor or outdoor?
It depends on where the cushion lives. For interior RV seating and sleeping areas — dinettes, jackknife sofas, berths, cab seats — our indoor HR foam (2.8 lb high-resiliency) is the right choice. It is CertiPUR-US certified, durable, and gets more comfortable over time. For cushions in awning areas, exterior storage bays, or anywhere exposed to rain and moisture, our Dry Fast outdoor foam is the correct choice — water passes straight through so it never stays wet or grows mold.
