What They Have in Common
Both are offset-position mats sitting 2 inches or more thick. Both accept real tees. Both are sold as single SKUs with no variants to sort through. And both sit in the $1,200 range at list.
Where They Differ
Size and layout
The Fiberbuilt Grass Series Studio 7×4 measures 85 in × 49 in. The SIGPRO Softy 4×10 measures 120 in × 48 in. That extra 35 inches of length is the big story here — the SIGPRO gives you a full 10 feet of mat to work with, which means room for a launch monitor off to one side without needing a separate pad or a piece of plywood. Fiberbuilt's answer to the same problem is the 2 ft × 4 ft spacer section sized for an optical launch monitor, in a shorter mat.
Thickness
The SIGPRO Softy 4×10 is 2.5 inches thick; the Fiberbuilt Grass Series Studio 7×4 is 2 inches thick. That half-inch is the difference in surface height if a launch monitor is sitting on the mat.
The hitting surface
Fiberbuilt's panel is a 1 ft × 4 ft hitting zone with UV-inhibitor-coated nylon fibers and four tee holes that fit standard rubber tees or friction-fit holders. The guarantee is 300,000 shots. One rubber tee and one friction-fit real-tee holder come in the box. Worth noting: the adjustable tees this panel was designed for are listed as temporarily discontinued, so the hole pattern exists but the matching hardware isn't currently available.
The SIGPRO Softy's strip is Teeline turf over a foam insert with three compression slots and a thin ABS polyurethane layer underneath. It takes real tees at adjustable height — no tee holder needed. And when it wears out, you replace the strip rather than the whole mat. SIGPRO publishes no swing guarantee for it.
One flag on the SIGPRO: its strip height is listed as 2⅜ in on this mat and 2½ in on the 4×7 version. Whether that's a typo or a real difference, The Indoor Golf Shop doesn't clarify.
Warranty and weight
Fiberbuilt breaks its warranty into layers: 1 year on the stance and turf mats, 5 years on the rubber base. The Indoor Golf Shop publishes no warranty for the 4×10.
Fiberbuilt publishes no weight. The SIGPRO Softy 4×10 weighs 31 lbs.
Who Should Buy Which
Get the SIGPRO Softy 4×10 if:
- You want a 10-foot mat that has enough room for a stance, a swing, and a launch monitor without adding a separate pad
- A replaceable hitting strip matters to you — worn strip, swap it; no need to replace the whole mat
- You want to know what the thing weighs before it shows up at your door
Get the Fiberbuilt Grass Series Studio 7×4 if:
- The 300,000-shot guarantee on the Fiberbuilt Grass panel is something you actually value and plan to hold them to
- Your space is tighter and a 7-foot mat fits better than a 10-foot one
- You like the modular rubber foundation and the tool-free assembly that comes with it
The Bottom Line
The SIGPRO Softy 4×10 is longer, publishes its 31 lb weight, is cheaper at list, and its hitting strip can be replaced without buying a new mat. The Fiberbuilt Grass Series Studio 7×4 counters with a well-specified guarantee on its hitting panel and a 5-year warranty on the rubber base — and if the footprint of a 10-foot mat is a problem in your space, the 85-inch Fiberbuilt fits where the SIGPRO won't. But on the numbers alone, the SIGPRO wins the comparison.
