Our pick for oversized lounging: Cosac 7ft
The 7ft Cosac is our choice here for a sprawling foam seat. At a listed 84 inches across, it is a full foot wider than Lovesac’s 6ft BigOne. That extra room is a central reason to choose it: this is a comparison of two oversized loungers, and Cosac offers the wider footprint.
The BigOne earns consideration for its fabric selection and lifetime limited insert warranty. Those are useful ownership features, but they do not make it the larger seat. Our recommendation weighs the published specifications and complete purchase; we have not run a side-by-side comfort test.

| Size & weight | 7 ft size: approximately 84 in wide and 55 lb. Other dimensions should be confirmed with the seller. | Approximately 72 in wide × 49 in high; 95 lb. |

7ft vs. 6ft: the actual measurements
Cosac lists the 7ft model at approximately 84 inches in diameter and 55 pounds. Lovesac lists The BigOne at approximately 72 inches wide, 49 inches high, and 95 pounds. These are manufacturer measurements; foam seats change shape with fluffing and use. Diameter describes the outside of the bag, not a flat usable seat.
MovieSac is approximately 4ft wide and SuperSac approximately 5ft wide. They are smaller Lovesac options, not the 6ft model in this comparison. Cosac also sells 5ft and 6ft versions, so check the size selected in the cart rather than relying on the brand name alone.
Mark out a seven-foot circle where the Cosac will go and a six-foot circle for The BigOne. Leave a route around the seat and room to open nearby doors. This makes the difference tangible before either expanded foam insert arrives.
Compare the complete seat price
Cosac’s size table listed the complete 7ft package at $399 when checked on September 9, 2026. That includes its outer cover, inner bag, and shredded foam. Use the 7ft price when comparing: the brand’s lower starting price belongs to the smaller 5ft model.
For Lovesac, select a BigOne insert-and-cover package in the fabric you want. Cover-only prices and bundles with a Squattoman are different purchases. Promotions also change, so compare the final total for both complete seats before adding accessories.
Covers, upkeep, and delivery
Cosac’s removable Sherpa cover is washable, and the brand lists replacement parts. Lovesac offers a wider cover selection; follow the care instructions for the fabric you choose. Its lifetime limited warranty applies to the insert under its terms, with different coverage for covers.
At our check, Cosac’s product page warned of roughly four weeks from manufacture to arrival, despite a faster estimate elsewhere on its site. Confirm the selected configuration’s delivery date. For either brand, check return eligibility and how an expanded bag is collected before committing.
Which would we buy?
We would choose the 7ft Cosac for a large lounge or movie room where stretching out is the point. It gives you more width than the 6ft BigOne, and the complete package makes the purchase easy to compare. Choose The BigOne when a particular Lovesac fabric or its insert warranty is worth the additional cost to you.
If neither fits the room, step down to a smaller model from either brand. For this oversized comparison, though, the size advantage belongs to Cosac.
