What They Have in Common
Both are modular Fiberbuilt systems that assemble tool-free, and both require a firm, level surface — not bare ground. Both use the same offset hitting position, include a spacer panel designed for a launch monitor, carry a 5-year warranty on the rubber bases, and have a 1-year limited warranty on the turf mats.
Where They Differ
The Hitting Panel
This is the comparison. The Grass Series gives you a 1 ft wide Fiberbuilt Grass panel — UV-coated nylon fibers, four tee holes, and a 300,000-shot guarantee. The Player Preferred gives you a 2 ft wide Pure Impact Turf panel with no shot guarantee from Fiberbuilt. Whether that guarantee matters to you depends on how much you trust the material it covers, but it's a real spec difference: one product backs its hitting surface in writing, the other doesn't.
A 1 ft hitting panel is narrow. You can make it work, especially with the offset layout, but the Player Preferred's 2 ft panel gives you more margin. That's not a feeling — it's just more hitting-panel width.
Overall Size
The Grass Series Studio 7×4 measures 85 in × 49 in. The Player Preferred Studio 8×4 measures 97 in × 49 in. That 12-inch length difference is where the extra hitting-panel width lives. Width is identical at 49 in on both.
Thickness
The Grass Series is 2 in thick; the Player Preferred is 1.75 in — a 0.25 in difference. If your device is floor-standing, that quarter-inch is the difference in surface height between the two mats.
Tee Setup
Both include a friction-fit real-tee holder. The Grass Series also throws in a rubber 2.625 in tee and is designed for Fiberbuilt's adjustable tees — which are listed as temporarily discontinued. So that designed-for compatibility exists on paper right now, without the matching product available to buy.
Weight and Spacer Orientation
Fiberbuilt doesn't publish a weight for the Grass Series. The Player Preferred weighs 133 lbs. That's a meaningful data point for anyone moving the mat between rooms or storing it seasonally. The spacers also differ slightly in stated purpose: the Grass Series spacer is sized for an optical launch monitor; the Player Preferred's is described for a face-on launch monitor. If you're already committed to a specific device and orientation, that's worth checking.
Who Should Buy Which
Fiberbuilt Grass Series Studio 7×4 ($1,249)
- You want the Fiberbuilt Grass panel specifically — the shot guarantee means something to you, or you've used the material before.
- The 85-in footprint fits your space and the 1 ft hitting panel doesn't concern you.
- You're pairing it with an optical launch monitor and want the spacer sized for it.
- Saving $250 at list is part of the decision.
Fiberbuilt Player Preferred Studio 8×4 ($1,499)
- You want a 2 ft hitting panel — the everyday practical choice for a permanent hitting bay.
- You're running a face-on launch monitor and want the spacer matched to that setup.
- You need to know the mat's weight before buying (133 lbs is the only published weight here).
- The 97-in footprint works in your space.
The Bottom Line
Both mats are the same width, same warranty structure, and same general modular system. The differences are the hitting panel width, the length, the thickness, and $250 at list. If you want the 300,000-shot guarantee and can work with a 1 ft panel, the Grass Series makes sense. For most people building a bay they plan to use daily, the 2 ft panel on the Player Preferred is the right call — it's the more straightforward setup.
