Our take
Cosac 6ft has the larger stated round diameter. The named Big Joe Fuf 7Ft costs less and has a narrower stated footprint, despite the larger nominal size label. Both use foam and a removable washable cover in the configurations compared.

What changes the decision.
Six feet and seven feet use different conventions
Cosac’s 6ft is a 72-inch diameter. Big Joe’s 7Ft refers to an approximate diagonal; the maker lists about 62 by 51 inches across the floor. Do not choose between them by the label alone.
The price and fill both need their own lines
Cosac describes shredded memory foam. Big Joe describes recycled polyurethane foam from unused scraps. The lower listed Fuf price is a purchase fact; it does not establish lower comfort or an identical fill.
The fabric choice changes care
This Fuf recommendation concerns Midnight Blue Corded Plush. Other fabrics can have different cleaning rules. Cosac’s sherpa cover and the Fuf cover both require attention to their exact care instructions.
What we have not established
We have not compared these products in a controlled sitting, washing or long-term wear test. The model descriptions support conclusions about the purchase, format and published care, but not a universal winner for comfort or quality.
Cosac 6ft: Dimensions, weights and capacity descriptions are manufacturer specifications, not measurements taken by the Edit.
Big Joe Fuf 7Ft: Do not compare its nominal 7Ft label directly with a seven-foot diameter. The listed dimensions and price apply to this configuration.
