GDBEH Boat Seat Swivel Mount 6.3x6.3 inch Black, 6" Black (2PCS) pedestal bases with 360° load-assisted rotation

GDBEH 2Pcs Boat Seat Swivel Mount is a heavy-duty 6.3 x 6.3 inch pedestal base that provides smooth, load-assisted 360° rotation and supports up to 500 lbs for boats and multipurpose seating.

This pair of swivel mounts is designed for anglers, boat owners, and anyone who needs a durable, corrosion-resistant pedestal base. Built from 2.4 mm high-strength steel with a black protective finish and an integrated thrust bearing, the mounts deliver controlled rotation under load and a stable platform for standard boat seats and many pedestal systems. They are a versatile upgrade for jon boats, pontoon boats, yachts, and even non-marine seating like bar or counter stools.

How does the load-assisted swivel improve seat movement?

The integrated thrust bearing reduces resistance and distributes vertical load, enabling smoother 360° rotation while seated. That makes turning easier under full weight and increases controllability during on-water maneuvers.

• Integrated thrust bearing for smoother rotation under load
• Even load distribution minimizes binding and wear
• 360° spin designed to feel stable while seated

Will these bases fit my boat seat or pedestal?

The mounting plate measures 6.3 x 6.3 inches with hole spacing that ranges center-to-center from 4.5 to 5.5 inches, matching most common seat patterns. Check your seat or pedestal measurements against the detailed dimension drawing to confirm compatibility before ordering.

• Plate size: 6.3 x 6.3 inches fits common seat flanges
• Hole spacing: 4.5"–5.5" center-to-center for most patterns
• Works with standard marine pedestal systems and aftermarket seats

How durable and marine-suitable are these swivel bases?

Manufactured from 2.4 mm high-strength steel, each mount supports up to 500 lbs and has a flat, smooth plate for stable installation and rotation. A black protective coating improves corrosion resistance in saltwater environments, and the weld-free design simplifies mounting and reduces potential corrosion points.

• 2.4 mm high-strength steel construction for longevity
• Black protective coating to resist corrosion in marine use
• Weld-free design reduces rust-prone seams and eases installation

Can these mounts be used outside the boat?

Yes — the design accommodates many non-marine applications where a sturdy, swivel seat base is needed. Use them for bar stools, counter seating, display stands, or any setting that requires a robust rotating base rated for heavy loads.

• Compatible with household and commercial seating like bar stools
• Useful for display stands and workshop seating that require rotation
• Two-piece set makes it simple to outfit multiple seats or spare mounts

They also suit workshop and hospitality settings needing reliable swivel seating. Confirm your seat/pedestal hole pattern and intended environment (freshwater or saltwater) to choose the right mount and protect it with routine maintenance for the longest service life.
