Bumfortable kayak seat

Not a good option for a sea kayak..
The seat will NOT stick into a fiberglass kayak no matter what you use. Glue, velcro, nothing works. The minute you brace with your feet it dislodges. Also there is no thigh support so you have to figure that out and if you use any screws the seat is so flexible the screws will tear.
Last comment is the seat is too high for a sea kayak. So unless you are a craftsman who can shave off a lot of the bottom without ruining the seat, the boat will wiggle as your center of gravity will be too high.

I have been kayaking for about eight years and I own about a dozen kayaks, and one of my Valley Nordkapps has the Bumfortable seat. Although it is comfortable to sit in, and comfortable when sitting upright such as kayak marathoning, I do not find it nearly as useful for more dynamic kayaking. Rolling, deep bracing, reverse stoke are simply not side-supported enough by the Bumfortable seat. The foam is not really closed-cell, not truly open cell either, but something in between. This leads to flex, and flex is not good (except for comfort under the buttocks). The manufacturer has an optional band that goes around the seat, and my kayak came with the seat and band, but the band seemed not to make much difference. My other kayaks either have stock Valley or Prijon seats and backbands, or I have custom shaped and fit gray, closed cell foam. This option is much preferred if a kayaker is going to be dynamic and move in the cockpit and desires a form fit for dynamic use. Not only do I get a better "purchase" and more seat and back stability for forward stroke power with true minicell, closed cell foam, but it’s also more ideal for rolling, etc. The intimacy of the hips and thighs is mandatory for proper boat control, and is the virtue of traditional seating or minicell. The Bumfortable, however, has a higher back than necessary, in my opinion, and has an emphasis on comfort over performance, and does not permit the stability around the hips and thighs to allow for ideal boat control.

Two additional issues regarding the Bumfortable: the installation/gluing and the price.

The foam is so "flexy" that the seat quite easily pulls up from the kayak bottom. I use the traditional method of installation, which is to clean the fiberglass or plastic thoroughly, including alcohol, allow to dry then use DAP Weldwood and allow some drying for super "tack", and then adding the seat. While this tried-and-true method works wonders for minicell (hard to remove even if you want to get it off, actually), the flexing Bumfortable will untack and come off on you during paddling. Its’ just too flexy, too open-celled, and the one-piece high back nature of the seat will have you putting direct pressure through it on each forward stroke. A two-piece traditional seat plus backband, for instance, does not allow direct pressure on the backband to be translated to the seat because they are independent units. I have had the Bumfortable pull detach frequently and frustratingly, even once on the first paddle a couple days after meticulous gluing; I have never had minicell come off, ever. A dislodged seat would be catastrophic on an expedition.

The price of the Bumfortable is high. The cost of closed cell/minicell is relatively much cheaper. Minicell can be obtained from most kayak general retailers, and in generic form at online auction sites. Shaping is so easy with a hacksaw and rough grit sandpaper, I don’t know why anyone would use anything else. A custom minicell seat that one could make themselves would be, based on my experience, about 1/3 the price of the Bumfortable seat.

All in all, the Bumfortable would not be the best choice for a sea kayaker who values a roll, paddles dynamic (sometimes violent) seas-- the side support and back support are inadequate for bracing, cockpit maneuvers and strong support for a power stroke (e.g. I could never imagine a kayak sprint racer using a Bumfortable). A traditional stock seat and backband, or minicell custom, would be preferred for sea kayaking.

That said, in thinking who might use the Bumfortable seat successfully, I would guess that it might indeed be reasonable for a long-distance, non-rolling (esp. if flatwater) kayak marathoner. It would also be reasonable for a flatwater recreational kayaker, although rec kayaks are typically inexpensive and buying an expensive seat for an inexpensive kayak is counterintuitive. A kayak fisherman might desire a comfortable seat for a wide, stable kayak fishing vessel; I am not a kayak fisherman, and can say that the Bumfortable would be like a cushion on the buttock for long term sitting, but I do not know if the fisherman, with hands preoccupied by rod and gear, needs to control the boat with hips and body movements. If so, the Bumfortable falls short.

I appreciate being able to post my thoughts on two years of use of the Bumfortable, and a simple counterpoint to the opinions already provided here. Thank you.

Such was the case with my Thunderbolt seats. The stock seat held me snugly and left me feeling secure in the boat, but (and perhaps this seat was modified by a previous owner) the back of the seat was such that the edge would cut into my back, especially if I used any significant amount of rotation in my stroke. My legs and buns would get numb after awhile as well. Using a back strap took away the back discomfort - as long as I was paddling casually. When I got aggressive (as in racing) and used a lot of rotation, I would end up with significant back chafing from the strap. I tried various padding schemes, but nothing really worked well. My lower back looked like I had been whipped and beaten in a POW camp.

With the stock setup not working for me, I opted to try the Onno seat. Reviews of this seat were glowing in admiration for the seat, and my experience with other Onno products was very favorable, so I called Pat and got one on order, getting the seat installed and briefly tested a week or so before the 2009 USCA Nationals. Not wise. The Onno seat is an excellent touring boat seat, but in my race boat I found it too wide and flat, leaving me feeling disconnected from my boat (which seriously compromised my performance in the swirling waters of the Allegheny river at the Nationals). Also, when I tried it without the back rest, the edge of the seat cut into my back. With the back rest it was much better, and the smooth back rest chafed me less than the back straps I had tried previously, but it still was rubbing me. At the Nationals I picked up some padding and got a good fit with the seat, using it fairly well in an 18 mile race the following week, but it still didn't give me as much rotational freedom as I desired. It was also a little heavier than the stock seat, and seemed to place my center of gravity a little higher. The quest for a better seat continued.

During the course of my search for a better seat for the Thunderbolt, I came across an interesting kayak seat called the Bumfortable (as in, keeping your buns comfortable!) from Gurney Gears. A wildly colored seat, made from closed-cell plastic foam, the Bumfortable seat promised to be an ergonomic seat that would provide support and cushion in all the right places, while having a slippery enough surface to allow body rotation for a proper forward stroke. Other claims included: warmth, reducing pressure points by redistributing the load over a larger area, light weight, no water absorption, low center of gravity, and - very important to me - structural back support without the chafing of back straps, etc. As a bonus, I read on a racer's web site the story of an individual who had installed a Bumfortable seat into his Thunderbolt, and really liked it:

Time to get out the credit card!

I ordered the narrower model, even though others had said they were able to get the wider model to fit the Thunderbolt. I think it was a good decision; the seat fit the Thunderbolt about like it was made for it - and for me. Like most people, I tried sitting in the seat before placing it in my boat, and found it was a little uncomfortable. There's a rise in the middle of the seat that kind of feels like it's going to give you a wedgie. Once in the boat, however, the seat felt great.

Gurney Gears shows how to glue the seat in place, but I opted to use 2 inch wide industrial strength self-adhesive Velcro hook and loop fastener material instead, a trick used by other paddlers in the area. After removal of the Onno seat, I used a cleaner/degreaser to clean the inside of the hull, followed by the use of rubbing alcohol as a final degreaser. I then attached a couple of strips of the Velcro material to each side of the channel running along the bottom of the seat. Having already test fit the seat to the boat, I knew where I wanted it placed, so I attached the mating Velcro material to those strips, removed the backing, and placed the seat in the desired position. It was easy and worked great. When I sat in the boat, the seat conformed to the bottom of the boat, and the seat sides provided just the right amount of foam padding between me and the cockpit sides (actually the stock seat hangars).

A couple of days after installation I headed out to the river for an 18 mile run - 9 miles up paddling at race pace, and a casual return trip after joining up with a recreational group coming down stream. My experience in the past has shown me that some seat seem ok when you're pushing hard, but hurt your back when you slow down. Conversely, a good touring seat is usually poor when you're going all out.

When all was said and done, I was very pleasantly surprised to find this seat seems to do all things well. I felt more connected with my boat and more stable than I've felt with any other seat. At the same time, I was able to really put the power to the water, getting plenty of rotation without any rubbing against my back. I think I ran some of my fastest times ever on that section of my local river, a combination of feeling secure in the boat and the ability to put my full power into the paddle. The Velcro installation worked great - the seat never even hinted at moving. If necessary, though, I could remove it and relocate the seat to fine tune the boat. During my outing my back was comfortable whether I was running hard or taking it easy. It seems to provide support to the back in just the right places, while avoiding rubbing in more tender areas. The seat definitely feels warm and comfortable. It's not hot and sweaty, just warm. It should make the boat feel pretty comfortable in winter.

If you need an improved seat in your kayak, and you can get past the wild colors, I would highly recommend the Bumfortable seat for serious consideration.
