If you do step into quicksand, you'll only sink in a little deeper than your waist. I would say there would be some pressure on the chest, but not enough to cause serious trouble.

So how do you get out? Don't ask your friends to tug on you; they're likely to pull you into two pieces if [they] try hard to pull [you] out.
The way to do it is to wriggle your legs around. This creates a space between the legs and the quicksand through which water can flow down to dilate [loosen] the sand. You can get out using this technique, if you do it slowly and progressively.

A person will gradually begin to sink in quicksand, and movement will make the victim sink faster. This may be the origin of the advice to "never struggle if you're caught in quicksand."

So take the advice and never struggle in quicksand.

the following steps may help:-

Avoid quicksand. Any time you are in an area of wet ground, such as along beaches, marshes and rivers, or if you are in a place where underground springs bubble up, you might encounter quicksand. Be on the lookout for ground that appears unstable. Often, you can't detect quicksand just by looking at it. If you step on ground that ripples or shifts beneath you, step backward quickly and smoothly: quicksand usually takes a second or two before it liquefies.
Walk softly and carry a big stick. When hiking, especially in an area you suspect contains quicksand, carry a long, stout pole. You can use the pole to test the ground in front of you, and you can also use it to help extract yourself should you sink (see step 9)
Drop everything. Because your body is less dense than quicksand, you can't fully sink unless you panic and struggle too much (which will cause the sand to further liquefy) or you're weighed down by something heavy. If you step into quicksand and you're wearing a backpack or carrying something heavy, immediately take off your backpack or drop what you're carrying. If it's possible to get out of your shoes, do so; shoes, especially those with flat, inflexible soles (many boots, for example) create suction as you try to pull them out of quicksand. If you know ahead of time that you are highly likely to encounter quicksand, change out of your boots and either go barefoot or wear shoes that you can pull your feet out of easily.
Relax. Quicksand usually isn't more than a couple feet deep, but if you do happen to come across a particularly deep spot, you could very well sink quite quickly down to your waist or chest. If you panic you can sink further, but if you relax, your body's buoyancy will cause you to float.
Breathe deeply. Not only will deep breathing help you remain calm, it will also make you more buoyant. Keep as much air in your lungs as possible. It is impossible to "go under" if your lungs are full of air.
Get on your back. If you sink up to your hips or higher, bend backward. The more you spread out your weight, the harder it will be to sink. Float on your back while you slowly and carefully extricate your legs. Once your legs are free you can inch yourself to safety by using your arms to slowly and smoothly propel yourself. If you are very near the edge of the quicksand, you can roll to hard ground.
Take your time. If you're stuck in quicksand, frantic movements will only hurt your cause. Whatever you do, do it slowly. Slow movements will prevent you from agitating the quicksand—the vibrations caused by rapid movements can turn otherwise relatively firm ground into more quicksand. More importantly, quicksand can react unpredictably to your movements, and if you move slowly you can more easily stop an adverse reaction and, by doing so, avoid getting yourself stuck deeper. You're going to need to be patient; depending on how much quicksand is around you, it could take several minutes or even hours to slowly, methodically get yourself out.
Get plenty of rest. Other than panic, exhaustion is your worst enemy. Since it can take a long time to get yourself out of quicksand, be sure to take breaks and just float on your back if you feel your muscles getting tired. If you're in a dangerous tidal zone, however, you may be in a race against time (see warning below).
Use a stick (optional). A stick is not necessary to extricate yourself from quicksand, but it can be helpful if you have one.


As soon as you feel your ankles sink, lay the pole on the surface of the quicksand horizontally behind you.
Flop onto your back on top of the pole. After a minute or two, you will achieve balance in the quicksand, and you'll stop sinking.
Work the pole towards a new position, under your hips. The pole will prevent your hips from sinking, so you can slowly pull one leg free, then the other.
Stay flat on your back with your arms and legs fully touching the quicksand and use the pole as a guide. Inch sideways along the pole to firm ground.



Tips
There are a couple approaches to extricating your legs from quicksand. If the quicksand is very thick, you can move your legs in a circular motion. This will help introduce more water into the quicksand, which will make it easier to pull your legs out. If the quicksand is not particularly thick, you should just be able to pull your legs out slowly, one at a time, as you float on your back. If you try one of these methods and find yourself starting to sink, stop immediately and remain calm. Breathe deeply and let yourself rest and float before trying the other method.
Never hike alone, always have a buddy.
If you hike with someone else in an area where you're likely to encounter quicksand, bring along at least 20 feet of rope. That way if one person falls in, the other can stand safely on firm ground and pull him out. If the person on firm ground is not strong enough to pull the victim out, the rope should be tied to a tree or other stationary object so that the victim can pull himself out.



Warnings
While it's possible to die of exposure (hypothermia) from being stuck in cold quicksand for an extended period of time, most quicksand-related deaths result from drowning. Most people who drown because of quicksand do so on beaches or tidal flats, where quicksand is common and where a person can become trapped as the high tide comes in. If this is a concern try to get out as quickly as possible, but still do not panic, as that will only hurt your efforts. Keep your head as high above ground (and water) as possible in order to give you more time if you are still stuck as water approaches. Generally, however, by the time the tide comes, it is too late. The best solution is prevention. Avoid crossing mudflats or other tidal areas or exercise extreme caution when doing so. Know when the tides will come in, do not go alone, and carry rope, a stick and a flotation device that you can easily inflate should you become stuck. And, of course, whatever you do, avoid putting your head under the quicksand, even for an instant.
While choosing to hike barefoot may protect you from quicksand, it can expose you to parasites that enter through the skin, such as hookworms and strongyloides.

I just saw something about this on television had had completely missed an important factor, personal boyancy. The tactic for a skinny person is *not* the same as for one with higher body fat.

A fatter person can try to get level and relax and hope for help.

A skinny person who relaxes will just sink. It's not that they don't float because they're stubborn and won't relax, it's because their specific gravity is greater than the material around them.

All quick sand is not created equally. Some is deeper (skinnies are out of luck) and some is very heavy. The heavy stuff offers less resistance to s-l-o-w movement than to brisk movement. Panic makes things worse.

Work towards the nearest firm area and it's a good time for those who believe in prayer to do so, if only to avoid panic.

Quick sand deaths have been blown out of portion on the movies and TV; however, it can be dangerous and can suffocate a human at times. Generally, to avoid getting pulled down, you don't struggle, as while moving around you help create air pockets that give the pool of water, sand, mud and other sediments, the ability to have suction. Most of the time if you remain calm and spread your arms out, (your whole body if possible), you will not sink. You should always be traveling with at least another person when in swamp type areas or areas that have pooled waters. Traveling at least five feet apart will prevent both of you to hit the problem and the other can hand you a limb or rope or vine or something to hold on to, and then slowly pull you over to the side and then you can climb out, with the other person's help. If by yourself flatten out and slowly, I mean slow, inch over to the side. Just don't panic.

I heard (but have never tested) that you are supposed to lay down and roll your way out. Struggling and trying to use your feet to climb out will make you sink faster. I think it would be best to always travel with someone in quicksand areas. Then they can help pull you out while you lay on your side.

One last bit of advice (which I don't recommend) is from Homer Simpson
" It's okay. I'll just pull my feet out with my arms. And now I'll pull my arms out with my face. Blurbb"

How to Escape?If you ever find yourself in a pit of quicksand, don't worry -- it's not going to swallow you whole, and it's not as hard to escape from as you might think. The human body has a density of 62.4 pounds per cubic foot (1 g/cm3) and is able to float on water. Quicksand is denser than water -- it has a density of about 125 pounds per cubic foot (2 g/cm3) -- which means you can float more easily on quicksand than on water. The key is to not panic. Most people who drown in quicksand, or any liquid for that matter, are usually those who panic and begin flailing their arms and legs. It may be possible to drown in quicksand if you were to fall in over your head and couldn't get your head back above the surface, although it's rare for quicksand to be that deep. Most likely, if you fall in, you will float to the surface. However, the sand-to-water ratio of quicksand can vary, causing some quicksand to be less buoyant, if the quicksand were deep, as in up to your waist, it would be very difficult to extract yourself from a dense slurry, not unlike very wet concrete. The weight of the quicksand would certainly make it difficult to move if you were in above your knees.With quicksand, the more you struggle in it the faster you will sink. If you just relax, your body will float in it because your body is less dense than the quicksand.The worst thing to do is to thrash around in the sand and move your arms and legs through the mixture. You will only succeed in forcing yourself farther down into the liquid sandpit. The best thing to do is to make slow movements and bring yourself to the surface, then just lie back. You'll float to a safe level. When someone steps in the quicksand, their weight causes them to sink, just as they would if they stepped in a pond,If they struggle, they'll tend to sink. But, if they relax and try to lay on their back, they can usually float and paddle to safety, move as slowly as possible in order to reduce viscosity. Also, try spreading your arms and legs far apart and leaning over to increase your surface area, which should allow you to float.As long as you keep a cool head in the situation, the worst result will be a shoe full of wet sand

First, do not struggle as kicking your feet will only cause you to sink deeper. Relax. The truth is, most of us will only sink up to our neck in quicksand.

Slowly move your arms horizontally along the surface to pull your body into a horizontal position. Once you have achieved this, roll slowly to solid ground.
