Going to have to look at Masland or tuftex. Nylon is scarce now and gonna cost you these says

Triexta is pretty on par with nylon but not as expensive. Mohawk Smartstrand is the brand name. We have this stuff and it is very nice. I would generally avoid polyester unless you are thinking short term.

I know the Stanton Jazzy and it's brethren are likely from Belgium (at the very least the fiber is almost certainly). Unlikely to be solution dyed. Will almost certainly have some dulling after the first cleaning (if it's anything like their other glossy carpets). Not taking care of that carpet with the correct vacuum or not vacuuming a lot is going to be really bad. My guess is like all Stanton carpets that aren't wools, is it won't wear as well, at that price to anything that Shaw or Mohawk have for 1/2 as much. Plus the warranty is like 15 year wear ( https://cdn.bfldr.com/PMOA7OGQ/at/xnfctghkb8p4g5c8ffmrrcvf/W005.pdf?format=pdf ) That's partially the catch, they don't really warranty their residential carpets, if it's not manufacturing defect in like the first year it's gong to be challenging. It's also heavy as all hell, gets wrecked in shipping because 13'2", cones like an absolute devil on an Accucut. Is guaranteed to have a broken core. I've been to a store that stocks it. I've handled a few rolls of it and it was miserable to process. It looks and feels incredible when it's installed. It's exactly what Stanton is, a luxury brand that's about looks and feel above and beyond durability and price point. You can explain all this and people will still buy it because nothing else I am aware of feels like it, which is why Stanton, Nourison, Kane, Miliken and Joy exist, because if they have what you want no one else does, but you will pay for it. My Mom wants it in her living room really bad and I wouldn't turn her, or anyone else away from it. Stanton is also supplying Jazzy or one that is similar, to distributor/s, though I cannot get anyone to confirm that it's for 100% certainty is. Usually there is more gossip than church about these kinds of things, but I cannot get the full scoop. Though both side don't want me to figure out eithers margins so I guess I understand. It's also one of Stanton better selling lines. That's pretty much what I know. Edit: For selling the product I would tell what you feel about it, give the stats show a "comparable" Smartstrand/Anso /(whatever dixie/fabrica calls their nylon now). Say hey if you are looking for warranty, Mohawk/Shaw (i have more experience with them and claims, you may have different brands) they I know they will do X for you their wording especially with pets mean there is a chance, Stanton is likely no chance, it's a nylon, it's obviously soft it's got good density and it's pure luxury, they'll make the decision and you informed them of the risks, then sleep easy. I was in a store that stocked it Lady touched it said "I want this carpet right here, it's my dream carpet," sales person explain what I said above, she said "I'm old, don't have pets, I want that carpet through my whole house" sale was like 200 yards, swiped the card no questions.

Get triexta or smart strand carpet. Better wear than nylon or poly, the strand is smaller which makes for a softer feel. Get the nap/density you like, if it’s good carpet it’ll hold up. Go for a 10# pad, and make sure installers use power stretchers, not just kick it in. If you buy from a decent dealer you should get a good warranty on everything. More on reddit.com
