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.

    • Most comfortable seats !!
I had chartered a captain for a fishing trip on Dale Hollow Lake. The boat had a couple of these seats My bad back found them extremely comfortable and very supportive as well as very strong with the metal frame. I was so impressed with them I ordered three for my boat and sold my six month old seats on marketplace. It’s an awesome product and i highly recommend them ... 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

    • Super nice Seat
I have a son that weighs around 350 lbs. last week I took him fishing at our favorite lake. I noticed that my swivel seat that he was sitting in was not doing a good job of containing his mass. When I got home that evening I started looking around for a heavy duty seat that would work for him. After reading several reviews on different venues I settled on the Millennium Marine B-100. It looked robust and simple. I ordered it on Amazon Prime and the shipment was supposed to take 2 weeks. I received it in 4 days!! I took it out of the box and installed it in my boat in less than 15 minutes. I climbed up in the boat and tried it out myself. WOW!! This seat is great. It is rigid and secure. I weigh around 200 lbs. and I felt like I was sitting in an oversized chair. The mesh bottom seat felt very comfortable and I could feel it breathe not sticky vinyl like before. I can't wait until my son get's a chance to sit in it. I would recommend this any day over standard cushioned bass seats. I am going to get one for myself now. ... show more
