Description

As a Millennium Marine exclusive, the patented ComfortMax Seat is designed for years of solid use. It will not hold dew on those early morning fishing trips, drains water even in a downpour, and dries quickly - so say goodbye to wet seats. Unlike other seats made of exposed foam or rubber that breakdown and rot, the ComfortMax Seat will excel in use in all temperatures and weather conditions. The seat is also great in green for duck blinds and shooting houses. Arm rest straps on B100 are optional. All aluminum construction with tight, breathable, cool fabric that dries quick and is resistant to mold and mildew and is UV resistant to sun and elements.

  • “The Bass Throne You Didn’t Know You Needed”
The Millennium Marine B100 Boat Seat is like the recliner your grandpa won’t give up—except it’s made for fishing and doesn’t smell like mothballs. This thing’s so comfy, you might forget to cast a line. With its breathable mesh that keeps your butt cool and a frame sturdier than your in-laws’ opinions, it’s perfect for long days on the water. It’s big, bold, and built like a bass boat throne—just don’t blame us if your buddies start calling shotgun on your seat. ... show more

  • Cool and comfortable seat even for large folks
I bought the B-100 to replace our helm seat on an aging pontoon. To be honest I assumed that the side straps would be in the way, cut into my legs, or just be annoying. I was wrong...I am 6' and 300 lbs. The seat is very comfortable and holds my weight easily, even when sitting for an hour or two. Construction seems very robust and no raised eyebrow moments when first setting it up. The airflow is wonderful on warm days, and the side straps are not really even noticable. As others have noted the mount does slide the seat forward a bit, or at least it seems to, but caused me no issues. The way the seat frame is constructed a person could easily customize the mount bracket location. I don't know how it will hold up, but for the first 4 days of use I have nothing but good things to say. It's probably a little overpriced for what it is, but competes well with other seat designs and prices. 5 stars and would buy again.... Update after 1 month...seat rocks and wish my fishing boat had these instead of the standard crestliner seats. Elite CNC Routing and Woodworks makes some AWESOME accesories for this seat. I bought one and love it also ... show more

  • Best!
Best boat seat! Works great in my AlumaCraft. Need a post and bracket, so it gets expensive - but so worth it!
