Choosing between a tri fold vs quad fold tonneau cover often comes down to bed length and folding mechanics. Both MOSTPLUS options are soft, styleside covers for the Ford F-150. They share similar construction goals, but they serve different bed sizes. The tri-fold model fits the 5.5-foot bed, while the quad-fold version is designed for the 6.5-foot bed. This size difference dictates how the cover folds and how much bed space you retain when fully open. We compare their specs to help you pick the right fit.

Which one should you choose?
Choose MOSTPLUS 5.5 ft Tri-Fold Soft F-150 Cover if
- You have a 5.5-foot Styleside bed on your Ford F-150
- You prefer a cover that folds into three distinct panels
Choose MOSTPLUS 6.5 ft Soft Quad-Fold F-150 if
- You have a 6.5-foot Styleside bed on your Ford F-150
- You want a cover with double-sided tear-resistant vinyl and four crossbars
Verdict: The tri-fold cover is the correct choice for owners of the shorter 5.5-foot bed. The quad-fold cover is built specifically for the longer 6.5-foot bed, offering additional structural crossbars for stability. Match the cover style to your exact bed length to ensure proper fit and function.
Tri-Fold vs Quad-Fold Cover Specs
Cover Style
The MOSTPLUS 5.5 ft Tri-Fold Soft F-150 Cover uses a tri-fold design. This means the cover folds into three distinct sections. The MOSTPLUS 6.5 ft Soft Quad-Fold F-150 uses a quad-fold design. This style folds into four sections. Both are soft covers. The tri-fold creates larger folds. The quad-fold creates smaller, more compact folds. This affects how much space the cover takes up when folded at the front of the bed. The quad-fold typically allows for slightly more bed access when partially open. The tri-fold is simpler in mechanism. You choose based on how you plan to load gear.
Bed Size
Bed length is the primary differentiator here. The tri-fold model is made for a 5.5 ft bed. It fits the 67.1 inch styleside bed on the Ford F-150. The quad-fold model is made for a 6.5 ft bed. It fits the longer 2026 Ford F-150 styleside bed. You cannot swap these covers. A 5.5 ft cover will not cover a 6.5 ft bed. A 6.5 ft cover will hang over a 5.5 ft bed. Check your truck bed measurement carefully. The style does not matter if the size is wrong. Match the cover to your specific bed length first.
Structure
Both covers share a soft structure. They are not rigid hard covers. The tri-fold cover uses a soft material over a frame. The quad-fold cover also uses a soft material. It features heavy-duty aluminum powder-coated frames. It has four horizontal crossbars for stability. The data does not list specific frame details for the tri-fold model, but it is also a soft cover. Both rely on tension and straps for security. Neither offers the same rigid protection as a hard cover. You get flexibility and lightweight handling with both options.
Material
The quad-fold cover specifies double-sided tear-resistant vinyl. This material is designed to resist tearing and punctures. It is also waterproof and UV resistant. You can wash it with soap and water. The tri-fold cover data does not list specific material details. It is implied to be a soft vinyl or similar fabric. The quad-fold gives you more confidence in material durability based on the specs. Tear resistance is a key factor for long-term use. UV resistance helps prevent fading and cracking over time. This is a clear advantage for the quad-fold model.
Compatible Truck
Both covers are compatible with the Ford F-150. The tri-fold fits models from 2015 to 2026. It is for the styleside bed only. The quad-fold also fits models from 2015 to 2026. It is also for the styleside bed only. Both covers require no drilling for installation. The quad-fold includes a stick touch lamp. This is a minor added feature. The core compatibility is identical for the truck model and year range. You must select the correct bed size for your specific truck.
Which cover fits your bed size
You have a 5.5 foot styleside bed
Your truck requires a cover designed specifically for a 5.5-foot bed. This tri-fold model matches that exact length. The three-section folding design allows you to access your bed while keeping the folded portion secure. It fits styleside beds for Ford F-150 models from 2015 through 2026. This ensures a proper fit without overhang or gaps.
You have a 6.5 foot styleside bed
You need a cover for a 6.5-foot bed. This quad-fold option is built for that specific length. The four-section design folds into smaller segments, which helps manage the longer bed span. It features double-sided tear-resistant vinyl and aluminum frames. The no-drill installation makes it easy to mount on your styleside truck bed.
You want maximum folding compactness
The quad-fold design splits the cover into four sections instead of three. This creates a smaller folded bundle at the front of the bed. This is useful if you need to access the cab or side rails frequently. The additional hinge points allow for more granular folding control compared to the larger tri-fold sections.

Frequently asked questions
Does a quad-fold cover offer better cab access than a tri-fold?
Yes, the quad-fold design provides more compact storage when fully folded. The MOSTPLUS 6.5 ft Soft Quad-Fold F-150 folds into four sections. This creates a smaller bundle at the cab compared to a three-section fold. You gain easier rear visibility and quicker access to your truck bed.
Can I use a tri-fold cover on a 6.5 foot bed?
No, you must match the cover size to your specific bed length. The MOSTPLUS 5.5 ft Tri-Fold Soft Cover is designed exclusively for 5.5 foot beds. Using an incorrectly sized cover will not fit properly. Always check the bed size specification before purchasing a soft tonneau cover.
Are soft tri-fold and quad-fold covers secure?
Soft covers prioritize ease of use and compact storage over hard-shell security. Both MOSTPLUS options are soft structures made for convenience. They are practical choices if you need quick access. However, they do not offer the same level of theft protection as hard folding covers.
Which cover is better for a Ford F-150 with a 5.5 foot bed?
The tri-fold model is the correct choice for this bed size. The MOSTPLUS 5.5 ft Tri-Fold Soft Cover is a precise match for shorter beds. It delivers the correct dimensions for your specific truck configuration. The quad-fold option is sized for 6.5 foot beds and will not fit.

What is the main difference between tri-fold and quad-fold designs?
The difference lies in the number of folding segments. A tri-fold cover has three sections, while a quad-fold has four. The quad-fold design creates a smaller folded package. This allows for easier cab access and better rear visibility when the cover is stowed at the front.
