Our take
Choose Cosac 6ft if your priority is a lower-priced complete foam seat with a 72-inch listed diameter. Investigate SuperSac if the interchangeable Lovesac cover system is worth the higher named configuration price to you. We have not established that either is universally more comfortable.
Our picks compare published specifications and named configurations. We have not physically tested these products. Prices were checked on October 1, 2026, before tax, with no coupon assumed. How we choose
The comparable details.
| Model | Complete price | Published dimensions | Fill | Outer cover |
|---|---|---|---|---|
| Cosac 6ftSherpa-fleece cover, inner liner and filling included | $299 | 72 in diameter | Shredded memory foam | Removable, machine-washable sherpa-fleece cover. Follow the sewn-in care label. |
| Lovesac SuperSacInsert and Charcoal Wombat Phur cover | $1,325 | About 60 in wide × 46 in high | Shredded Durafoam | Remove cover; wash separately in cold water on the gentlest cycle and lay flat to dry. Confirm the exact cover label. |
Dimensions describe different forms: width, diameter and diagonal are not interchangeable. All figures above are manufacturer-reported. See each linked profile for caveats.
Choose Cosac 6ft if…
You want more stated diameter at a lower complete price and like the fixed sherpa-cover offering.
Choose Lovesac SuperSac if…
You value Lovesac’s interchangeable upholstery system and want to investigate its published 46-inch fluffed height.
What changes the decision.
The complete-price difference is specific
The Cosac figure covers its sherpa cover, liner and filling. The Lovesac figure covers the SuperSac insert with Charcoal Wombat Phur. These are two dated configurations, not a comparison with every Lovesac size or sale.
The larger footprint is not the heavier product
Cosac lists a 72-inch diameter and approximately 40 lb. SuperSac is about 60 inches wide and 75 lb. That illustrates why neither diameter nor weight should be used alone as a quality score.
The filling labels do not establish equivalence
Cosac calls its filling shredded memory foam; Lovesac calls its fill Durafoam. The retrieved descriptions do not establish identical composition, density or performance.
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.
Lovesac SuperSac: The price is for the named insert-and-cover combination, not a cover alone. Dimensions are approximate maker specifications.
A few useful answers.
Is Cosac more comfortable than Lovesac?
The source record does not support a universal comfort winner. A controlled comparison with named models and actual users would be needed.
