What They Have in Common
Both mats cover the full surface in a single hitting material — no separate hitting panel, no replaceable strip. You hit from anywhere on them, and when the turf wears, you're replacing the whole mat. Both sit on a rubber base — heavy-duty on the SIGPRO, a modular shock-absorbing foundation on the Fiberbuilt — and both run 2 inches or just over in thickness, and neither publishes a swing guarantee.
Where They Differ
Size and Shape
The Fiberbuilt is 49 inches by 49 inches — square. The SIGPRO is 60 inches by 48 inches — a rectangle that's longer front-to-back but slightly narrower side-to-side. Which footprint you want depends on your hitting bay layout. If your launch monitor needs detection space behind the ball along the target line, that extra length in the SIGPRO's 60-inch dimension could matter. If you want more room to step sideways, the Fiberbuilt's 49-inch width edges it by an inch. Measure your bay both ways before deciding.
Thickness
The SIGPRO runs 2⅜ inches thick; the Fiberbuilt is 2 inches. That's a 0.38-inch gap. That's the published figure on each; what it means for where your launch monitor sits is worth checking against the monitor's own specs.
Tees
Fiberbuilt says you can tee up anywhere on the mat using a standard tee straight into the turf. The SIGPRO's product page never says that. It contrasts itself with SIGPRO's Super Softy elsewhere on the site, but it doesn't make a tee claim for this surface. If teeing from the mat is part of how you practice, that's a real published difference.
Price and Warranty
The Fiberbuilt lists at $499. The SIGPRO lists at $799.99 — a $300.99 gap at list. Fiberbuilt publishes a 1-year limited warranty on the turf and a 5-year limited warranty on the rubber base. The Indoor Golf Shop publishes neither a weight nor a warranty for the SIGPRO Commercial Teeline 4×5. That's not a reason to assume there isn't one, but it means you'd need to ask before buying.
One logistics note: the SIGPRO ships freight. Factor that into your timeline and any potential return situation.
Who Should Buy Which
Get the Fiberbuilt Performance Turf Tee Box 4×4 if:
- You want the lower list price and can stay with a 49-inch square footprint
- Teeing from anywhere on the mat is part of your practice routine
- You want published warranty terms before you hand over money
- Your bay is roughly square and a square mat fits cleanly
Get the SIGPRO Commercial Teeline 4×5 if:
- You need 60 inches of front-to-back length and your bay layout calls for a rectangular mat
- The 4×7 or 4×9 upsize options fit your longer-term plans (the Fiberbuilt scales up differently)
- You're outfitting a commercial space and "commercial grade" is a spec your buyer requires — though you'll want to contact The Indoor Golf Shop directly about warranty terms
The Bottom Line
The SIGPRO is bigger in one dimension and lists at a higher price, but The Indoor Golf Shop doesn't publish a weight, a warranty, or a clear tee claim for it. Fiberbuilt publishes all three, prices the 4×4 at $300.99 less, and gives you a square mat that lets you tee from anywhere. For most home setups, that's the easier call. If you genuinely need the longer rectangle, the SIGPRO is the one — but get the warranty details in writing first.
