Thread: Memory foam

    Memory foam

    Has anybody tried the memory foam/egg crate pads from Wally World for a pad. Seems it would be softer but not sure how it would work insualtion wise. Seems like it would breath better?

    It would probably be war enough if you got one thick enough to support your weight. We have a MF matress that if I pull the blanket up when I leave bed in the morning it will still be warm for quite a while. The down side it that is is very heavy and once out of the plastic bag it decompresses into a very large size. Our mattress came packed down to 3 inches tall maybe and lofted to 12, and weighs over 100 pounds, same story on the MF pillows I have tried, they tend to be heavy. Not sure how big the pads would be but suspect they will be more bulk and weight than would be easy to pack.

    It will compress if you have it under you. And that means less r-value
    CCF does not compress much due to its stiff design.

    Memory foam can be sculpted/darted and made to fit the exterior of the hammock, and suspended from the outside. Take into consideration memory foam may absorb water.
    And may be subject to tearing/ripping if snagged.

    Actual memory foam would be way too heavy - it's somewhere around 5 lbs/cubic foot as I recall.

    I believe you are correct on that density for memory foam. If you could get some open cell polyurethane foam similar to the Hennessy Supershelter underpad, it should work as long as you had an appropriate covering for it.

    I am not worried about weight. The $20 1.5 inch memory foam pad at Wally World weighs probably 6lbs. My question is more allong the lines of insualtion. Would it provide insualtion needed?

    This thread is old, but one of the concerns was that the foam got hard when it was cold... there has been some discussion in the past (if you search on "memory foam" you'll find them) and it seems for one reason or another it was not the best solution overall. BUT ymmv.

    Cabela's sells something like that. It's a thin closed cell foam pad, 1/4" or so, glued to a 2.5" open cell foam pad. The whole thing is then enclosed in a water resistant bag/case (or they have a version without the case). The side with the ccf goes down, and provides insulation, and the open cell/egg crate style foam provides cushioning, and the cover helps protect it from getting wet. It's big, and heavy, but really comfy for tent or car camping. Not sure about long term use and how it holds up, but I slept on one that a buddy had, on a wooden tent platform, and I didn't feel the hard ground.

    If you're not worried about weight or size, you could always get one of the ones at WM you're talking about, and use some foam adhesive to stick it to a thin layer of CCF or Volara foam - or even get the Volara foam that has the adhesive layer made for sticking it down to pojer tables or the like. But at that point, you're in the ballpark price wise of getting one of the premade basic ones from Cabela's. *shrug* YMMV

    As far as using it in a hammock, it seems like it would be a lot of weight and bulk, for very little benefit. And if you add the layer of CCF like above, then it starts to get redundant.
