Futon recommendations

[Chuchum Ainer]

Anyone have any recommendations for a good futon?

I need something that looks ok, though "rustic" is fine.
The issue I'm running into is that the vast majority of convertible sofas etc are tiny. I want something at least standard twin length (74"), and preferably a full or queen size when open (~50" wide)

I found this
https://www.wayfair.com/furniture/pdp/wade-logan-flodin-80-futon-frame-includes-full-size-innerspring-mattress-w008511167.html seems perfect
and I'll pay $520 if that's what it is, but it seems to me that a whole bunch of sellers sell the same rebadged china item, and I'm wondering how durable and comfortable it is. eg https://www.amazon.com/Kodiak-Furniture-KFMOBBLCHALF5MD3-Monterey-Barbados/dp/B0719JSVM5 ,  https://www.amazon.com/Stanford-Futon-Set-Mattress-Available/dp/B00CHV2UHQ
