Lining a Fairtex Muay Thai heavy bag with memory foam?

[Capt.Canuck]

I was originally looking to purchase a filled bag, but due to logistical reasons (shipping $$$) I've ordered a 6' unfilled Fairtex Muay Thai banana bag.

I've read through a bunch of posts about filling a heavy bag. Lots of good information there.

A lot of the filled bags come with a closed cell foam liner. In thinking about sourcing the foam liner, the thought occurred to me that memory foam (the kind of thing used in Tempurpedic pillows and matresses for example) could be an even better choice.

Has anyone tried lining their heavy bag with 1-2" of memory foam? Pros and cons?

TIA for the input.

Memory foam, you mean the type that squeezes together and stays that way for like 30 seconds? Only if you want to hit it, then wait, then hit it, then wait for it to regain it's size again.

Don't worry about foam, just use rags cut up really small.

Seems like it would be soft on your wrists if it doesnt mold. may be nice if you are just starting training and want to ease into hitting the bag. But i feel it would be too soft to condition your legs or use for extended periods.

Good point, that was the downside I was thinking about - too little firmness (too much shock absorption) could be an issue.

In that case why do manufacturers highlight the use of "closed cell foam liners" in their filled heavy bags? I've seen this quite a few times and it seems to be marketed as a selling point.

Because they fll the bags with a pneumatic press. Bags filled traditionally will not be as dense. You will not need a foam liner unless you add a bunch of sand to the mix.

I have a Tempurpedic mattress. It's great for sleeping, but probably not for punching.

The foam reacts to body temperature, not just pressure. When you lie down on it, it takes a few seconds to mold around you -- a punch or kick is much to fast for the material to "do its thing". It reacts to a punch just like any firm, closed-cell foam.

Also, the foam is rock-hard when the surrounding air is cold. A friend of mine learned that the hard way last winter. She jumped onto the bed, thinking it would just absorb the shock and she'd sink right into it. She was wrong.

Ah, excellent point. That was the insight I was looking for, thanks.

I think you're right. A quick impact would not allow sufficient time for the properties of the memory foam to work.
