This product arrived on time, at my door, no signature required. It does in fact arrive in a duffel bag-shaped shell, but once you cut the drawstring and remove it from this encasing, it does the rest on its own. It expands to most of its intended size in the first 12 hours. The next 12 hours, the growth stabilized. I flipped it over and let it expand on the other side for another 12 hours, and by then I could tell it was ready to be used. However, be sure to roll it around the room for a while first; this fluffs it like a pillow, and it didn't arrive at its final shape until after being rolled around like a ball. If you find it too heavy to roll around, get a friend and make a game out of it! Expanded and fluffed, this Lounge Bag proved to be the crown jewel of my game room. I find it supremely comfortable, like a firm, 6-foot pillow. I'm a medium-build guy over 6 feet, and I sink into the bag really easily. With a blanket I could sleep in/on it. It does not feel overstuffed or lumpy, and the memory foam retains a small imprint of my last position on the bag. However, other reviewers report some problems with both of these elements, so it's possible there might be some variation in quality. There are two positions recommended in the sparse instructions provided. Each requires that you orient the zipper (which signifies the "back" of the bag) in a particular direction for either lounging or upright sitting. Both work fine, but the lounging position is a little more comfortable. The upright position makes the bag look oddly tall when not in use. The lounging position is really aesthetically appealing, even in a smaller room. The footprint for the lounging position turns out to be 4.5' by 4.5', and it ends up being between 1-2' tall. To contrast, a papasan chair is around 3' by 3' and most chairs in my house are a bit under 2' by 2'. The only complaint I might have is the sparsity of documentation that comes with the product; for example, I had to figure out on my own how rolling the bag around affects the shape prior to first use, etc. It's not even that clear who makes the product (Praxis, I guess?) and there's no company information besides the Overstock.com return policy. But the documentation does provide basic directions for first use, cleaning, and suggestions for positioning the bag. Still, my experience was entirely pleasant and I am delighted with the product. It was exactly what I was looking for. And the sheer value of the product, considering how rare it is to find this sort of item in brick-and-mortar stores, pushes my review score to a full five stars.
