What They Have in Common
Both are offset-position mats — the hitting panel sits to one side, stance area to the other. Both take real tees directly in the turf. Both are 48 inches wide. And both are built around a dedicated hitting panel or strip set into a larger stance area.
Where They Differ
Size and Layout
The Fiberbuilt runs 60 inches long. The SIGPRO runs 84 inches long — 24 more inches of mat, same 48-inch width. If your bay is tight front-to-back, the Fiberbuilt fits where the SIGPRO won't. If you've got the space, that extra length gives you more room to stand comfortably and, if you're using a floor-standing launch monitor, the SIGPRO's layout is specifically set up with space beside the hitting strip for one.
Here's the catch on thickness: Fiberbuilt doesn't publish one for this mat. The SIGPRO lists at 2.5 inches, though there's a wrinkle worth flagging: its own pages give the strip height three different ways (2⅜ in, 2½ in, and 2⅝ in). SIGPRO hasn't resolved that publicly, so if the strip height matters for your setup, it's worth contacting them before you order.
The Hitting Surface
The Fiberbuilt's hitting panel is a 1-foot-by-4-foot Fiberbuilt Grass section — a distinct grass-fiber construction that comes with a 300,000-shot guarantee. Fiberbuilt doesn't list that panel as separately replaceable, so there's no published path to swapping just that section.
The SIGPRO Softy's hitting strip is designed to be replaced. When it wears out, you swap the strip, not the whole mat. That's a meaningful difference in long-term cost if you're hitting a lot of balls. The SIGPRO strip is a foam-insert construction with an ABS polyurethane layer and compression slots — which sounds like engineering, but I don't work at SIGPRO, so I can't tell you exactly how that translates to feel.
Tees, Weight and Warranty
Both mats take real tees in the turf. The Fiberbuilt also has a 4-hole panel that accommodates Fiberbuilt's Adjustable Tees — though as of this writing, those are temporarily discontinued. It ships with a 2.265-inch rubber tee and a friction-fit holder. (A small flag: every other Fiberbuilt Grass listing says 2.625-inch; the Traditional 5×4 page says 2.265-inch. Worth double-checking before you lean on that figure.)
The SIGPRO weighs 21 lbs and breaks into two pieces to store. Fiberbuilt doesn't publish a weight for this mat.
On warranty: Fiberbuilt covers the rubber base for 5 years and the turf and stance mat for 1 year. The Indoor Golf Shop publishes no warranty for the Softy 4×7.
Who Should Buy Which
Get the SIGPRO Softy 4×7 if:
- You want a mat that can be refreshed over time — the replaceable strip means you're not buying a whole new mat when the hitting surface wears down
- You're setting up a launch monitor on the floor beside the mat; the layout accounts for that
- The $199.01 lower list price matters
- You need the extra 24 inches of mat length for a comfortable stance setup
Get the Fiberbuilt Grass Series Traditional 5×4 if:
- You want the 300,000-shot guarantee on the hitting panel and a 5-year warranty on the rubber base
- The one-piece solid rubber foundation matters to you more than a modular base
- You're in a tighter space and 60 inches of mat length is closer to what you've got room for
- The Fiberbuilt Grass construction is specifically what you're after
The Bottom Line
The SIGPRO Softy 4×7 lists for $199.01 less and delivers a longer mat with a replaceable hitting strip and published weight. The Fiberbuilt Grass Series Traditional 5×4 counters with a 300,000-shot guarantee, a one-piece rubber base, and a published 5-year warranty on that foundation where the Softy has none at all. For most buyers building a bay, the SIGPRO's replaceability and lower price point are the more practical combination. The Fiberbuilt makes sense if you specifically want that grass-fiber panel and the structural confidence of a one-piece base.
