I bought 2 of these not realizing how Huge they are... absolutely no room in my sons room for either of them and they both have their own rooms, but we started a home gym in our basement and that was a perfect place for both of these chairs. They actually made the whole room look perfect

I've been using one of these things for 3 years now, and absolutely love it. My living situation is currently temporary, and the space I have is very limited. This beanbag has been a perfect solution to replacing my couch and loveseat in my current situation, both of which had to go into storage. Usually beanbag filling gets squished over long term use, resulting in a totally flat bag that cannot retain its shape whatsoever after a year or two of regular use. The filling of the beanbag however is made of chunks of memory foam, and after 3 years of constant everyday use, this filling has remained bulky and retained its shape. The memory foam also allows the bag to conform to whatever shape it needs to to accommodate you sitting in whatever position is comfortable for you, and then retaining that shape perfectly until it is purposefully "fluffed" and reset. One word of warning however: the bag will likely be larger in reality than it may seem - I wasn't expecting how big it actually is when it arrived, but that did not cause any issues for me.

Very happy with this thing so far, the price tag is absolutely worth it in the long run since I would have likely replaced a cheaper beanbag several times by now.

TL:DR
I got short-changed on foam, and the foam was very lumpy. The bag itself is great, but I had to add finer foam to make it comfortable.

I'm breaking this into two parts; the bag and the foam.

5' micro suede bag: Excellent, 4.5/5.
The texture is comfortable and breathes well.
The zippers on both the cover and the interior sack move easily , and in both cases are double-zippers to prevent strain and foam going everywhere. One note is that the tab on one of the four zips was missing, and I had to fix it before I could open the bag to do the initial stuffing.
The bag itself is the perfect size for one person curling up and reading, watching TV, gaming, napping, etc. It is just big enough that a 5'10" me and my 5'0" wife can share it for a while comfortably.
The slip cover also has a strip of cloth that folds over to cover the zipper, which is a nice touch.
If I could buy JUST the inner and outter shells of the bag, I would get another of these and stuff it myself.

The Foam: Too little, too lumpy... 2.0/5
I wish I had taken a picture of the foam package on a scale before I stuffed my bag...
First, the bag is supposed to take 5-days to reach full expansion, with flipping/rolling regularly.. It's annoying, but sure, I'll wait. That said, I had to open the bag back up and break apart the foam by hand to get it to start expanding past just the edges.
Just to dispel the thought, the "chill sack" does not have cooling memory foam. It also is not what I would consider viscoelastic.... it's just kinda normal foam. It really doesn't seem to react to temperature at all, in either heat transfer or "thermo-reactive squish." But to make that worse, the foam is not well-shredded. We are talking fist-size lumps of the stuff. When sitting down, you really, really feel the lumpiness.
After waiting and working a lot with the foam, it was finally sitting at full diameter, but only sitting 24" high instead of 34" when freshly fluffed. That made me finally weigh the thing, which was supposed to be 51lbs. It was only 42 with the bag. When you sat down, if you didn't pile foam into where your butt would be, you felt the floor. It was also loosely packed enough that there was no back support, and even with a pillow you were not upright enough to watch TV. I had to add more foam.
There were just SO many issues with the foam on this one. I ended up buying another 15 lbs of foam from better foam dealers, and I'm still not up to 34" high.

Now that I've added a bunch of foam, its finally up to where I can enjoy watching TV and playing games in it. The finely shredded foam is helping make the large lumps more bearable.

My son purchased this chill sack for me for Christmas last year because I kept insisting that I wanted it. It is a staple of my living room now, and I use it every day. I love to plop in it first thing in the morning, cover up with a blanket and play fetch and toy tug with my little dog. I can comfortably throw the toy various directions. He runs and gets it and then leaps up in the sack with me. Then we do it all over again. It's wonderful to drag out into the middle of the floor (though it is pretty heavy) and snuggle down in it to watch tv or a movie. I've fallen asleep in it a couple of times. The cover is nice and soft and the perfect color to match my furniture. It is very easy to put on and take off and washes wonderfully. Everyone who visits loves it and wants to sit/lie in it over other furniture. The one who loves it the MOST though is my chihuahua, Chaco. He has taken it over as "his bed," and is in it more than me! My son recently visited and brought his dog. She is a Labrador Retriever. She loved the sack as well! You can see in the included pictures how large and accommodating it is! When the sack starts to get too sunken in for my liking, I just take a few minutes and flip it over a few times to fluff it up. Then it's usually good and fluffy for a week or so. The only thing I think would make the sack better is if the cover had a sewn-on handle on it. That would make it a lot easier to move around and to fluff up. Otherwise it is awesome!

This Chill Sack was a big hit for Christmas! As you can see from the pic, 2 adults can be on it comfortably (legs hang off) and room for kids. Two kids can sit comfortably for watching tv or gaming. They LOVE it and everyone who sees it, wants one! Big, comfy, what more could you want?
You can see from the pictures, it's huge. One picture has a moon pod in front...sigificantly smaller and only for one person. Moonpod is in front, so looks a bit larger than in real life. Moon pod is beads, Chill Sack is foam, both comfy. Moonpod has more support if you want a straight back, but Chill Sack is more comfy, snuggly.
I bought the extra 10 lbs of foam after reading reviews and it was worth it. It is so high and full now. Even my 250 lb husband doesn't bottom out.
Construction is great. Inner sack has two zippers (inner one does not have a pull on it, so kids cannot get into foam)!!!! Great feature. It was some work to get it open to add the extra foam, but that means the kids cannot get to the foam! Outer sack has 2 zippers too. Very sturdy.
When we opened the box, it was small and compacted, in the inner sack only. We dug our hands in and fluffed and pulled apart the compacted foam pieces. We were rough, but the inner sack is strong! By doing this right off the bat we got good expansion that day. Next two days we rolled it, kicked (gently), dug our hands in to feel for clumps to pull apart. After a few days, we opened the inner sack and added the extra foam, carefully so as not to make a mess. It was compacted too, so picked and pulled it apart ( again through the cover). The foam pieces are a variety of sizes, shapes, colors, and it is all clean and new. I don't know that it's "memory foam" but it does the job!
Construction is great...Strong, somewhat stretchy, inner sack with 2 zippers, nice microfiber outer sack cover with 2 zippers. I am impressed with the quality! Highly recommend! Spend the time in the beginning to pull apart clumps, get the extra foam (if you want a higher, firmer seat)...or start with the sack and see if you need extra foam later. You will not be dissappointed!
