I've had two LoveSacs in the past (SuperSac size) and they were great. They're huge Durafoam-filled bean bags, and they are very sturdy and comfortable. If you live in a US metro area, try Craigslist since they're kinda pricey new (I found and sold mine there when I moved). More on reddit.com

I own 2 LoveSacs. A CitySac (which has gotten heavy use) and a SuperSac which still resides packed up not opened in my basement. Wait for their crazy sales where it's almost 70% off. They're worth it quality wise.

The Sumo, Comfy and other competitors I've seen seem to wear too easily. Never pay full price.

I sit in a big joe shredded foam beanbag all night after I get home from work. When I was looking for bean bags I saw a ton of reviews saying these things go flat after a while. As a big guy I can say my bag is as comfortable as the day I got it around a year ago, I just have to fluff it every so often. I bought mine on prime day for about $100. To make it even comfier to sit up on, I use one of those pillows with arms. More on reddit.com

I worked lovesac production while in college. They are legitimately BIFL. Most people get rid of them because they're over it, few get to be worn out. They used to have a lifetime warranty that they would honor as well. LoveSac is using closed cell memory foam which is one of the reasons they're expensive. It's the 40-60 lbs of foam (several lay z boys worth) and shredding and shipping it is not an easy process. Regardless of age, when you pick them up and flip them over a few times they'll puff right back up as if they're brand new. They can hold you like a chair without being up against a wall. The big LoveSacs require about 10 yards of fabric, heavy duty zippers, stitching, etc, thats to both to removable covers and to shroud the insert, which is the other reason they're as expensive as they are. If you keep it 10 years being able to swap out the cover can refresh the look as the insert is the most expensive part. if instead you're going for a traditional bean bag, small, up against a wall, or just want to stay cheap, or plan on throwing it away in a couple years, that's fine, but note the ones filled with styrofoam peanuts or anything similar: they compress and don't come back. If you intend to keep a cheap one expect little, or that you'll need to refill it over and over and over. I'd avoid it as it's a nightmare mess to refill, you can't shape it as it has the structural Integrity of sand, and cannot hold you in a sitting position in the middle of a floor The competitors to Lovesac used to ship you a half empty bag and another bag of filler and have you fill it yourself. Not sure if this is still the case. Tldr. They're spendy, but do deliver and can be shaped to act as a chair / bed / recliner for 10 years±. More on reddit.com
