RE: [bolger] Trim to retain seat cushion

Slightly off subject—In my neck of the woods, kids start playing baseball in January and dutiful parents get to watch while sitting on aluminum bleachers. When it is in the 30’s (about 0 C), the bleachers never get warm and sitting is uncomfortable. A solution is a back packers’ ethafoam pad. Putting it on the bleachers will keep you warm and attract as many friends as can squeeze onto it!

Along this same line of thinking.  After we moved off our boat I bought myself a rocking chair that I thought might simulate the motion of a boat and put a one inch cusion on it.

Doug, this is really interesting. Now I know why I never liked thick soft cushions - thanks.

 

I sit comfortably for many hours a day on a computer chair with fairly thin, but stiff foam. On a wholesale level a major factor in the cost of foam is its weight because a foam that is twice as dense, has twice the expensive chemicals in it, and so costs twice as much to produce and then to ship as light foam does.

 

Cheap cushions have very light foam, don't provide much cushioning, but look thick and substantial and so sell well, especially because of their cheap price.

 

A thinner, but denser and stiffer (and more expensive) foam, will still provide adequate cushioning, and it will be less likely to squeeze the tail bone nerves because its dense and stiff and doesn't compress nearly as much as light foam does.

 

The best cushions use laminated foam, where you have a very thin layer of very soft foam (maybe 1/4" thick) on the outside, and then a thicker layer of stiffer denser foam on the inside. The most expensive cushions will tend to have 3 layers of foam, all with different densities and stiffness. This is much like a shock absorber for a car where there is a little bit of soft give, and then as compression increases it rapidly gets stiffer.

 

Sincerely,

Roger

Hi: For the stiff foam your wife doesn't like I have contact cemented two different foam densities together and on one mattress also tried a layer of the memory foam on top of the firm foam which was quite nice. The big problem in cooler climates is the condensing of body moisture in the mattress which one mattress company I visited was trying to eliminate with clear plastic and tuck tape. And then stuffing it into a mattress cover.
Depends on the foam density and thickness.
The berth cleats on my plastic boat dug in my legs bad,
After I made new cushions from top quality high density foam I never even felt the cleats. I loved my 4" thick 40# density cushions but they were too firm for my wife to sleep in comfort.

Put your foam blanks in and try a few different dimensions of cleat to see what you can get away with. Mock it up ashore if you can't do it in the boat yet.

BTW, my quick and dirty berth cushion method was...

Cut luan ply 2" smaller in each dimension than berth flat.
Cut the foam to shape with electric carving knife.
Couple spots of double side carpet tape to hold foam to board.
Then staple the upholstery cloth to the ply, just like a kitchen chair seat.
Just fold and tuck the corners. The tighter you pull the cloth the more "bullnose" you get in the cushion. If you get the foam a little rough at the cuts the "nerds" will telegraph through your cloth. You can pre-upholster with light cloth similar to peel-ply or with quilt batting to reduce print-through.

If you want I can measure cushions and the trim piece.

Tales was extensively remodeled in the early 80's by somebody who was
really good. I have her pretty torn apart right now refinishing what you
see in the photos. The remodel moved the cabin forward and made it a two
bunk off shore cruiser. The cushion retaining trim pieces fold down
across about two thirds of the bunk length, a couple of pieces of
plywood fit in and two of the back cushions fill in space to make a
double bed across the boat.

Thanks Harry. Two inches total or above seat? How thick are your cushions? A relevant point as someone else pointed out. Mine are yet to be built. ROGUE's interior was never completed past the roughed in stage, and castaway stuff got me by while I decided upon final solutions. Though I considered using velcro, I decided against it because I want the finished look of trim, and because velcro attached cushions will interfere with the seat locker lids.

You have a beautiful boat.

Depends on cushion depth. Make some test strips using scrap and see what
works.
