The short answer
The Cosac 7ft is our first shortlist choice when maximum stated round diameter is the priority: the maker lists 84 inches. Jaxx Cocoon 6 suits a flatter, full-length lounging arrangement. Big Joe Fuf 7Ft offers a lower-priced foam option, but its 7Ft label refers to an approximate diagonal.
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
What earns a place here
We looked for large foam-filled seats with published dimensions and a cover or liner system that can be explained clearly. We compare dimensions in the same unit and keep diagonal size, width and diameter distinct.

Our shortlist.
01 / For the largest stated round diameter
Cosac 7ft
Its 84-inch published diameter is the clearest reason to put it first for a room with abundant floor space. The $399 complete price also makes the package easy to compare.
$399
Sherpa-fleece cover, inner liner and filling included
- Cover, liner and filling are included.
- Filled liner stays separate when the outer cover is removed.
- Requires a substantial clear floor area.
- Foam density and an independent durability test are not available in our source record.
Plan the room around its seven-foot diameter, including space to walk past.
02 / For a flat lounge surface
Jaxx Cocoon 6
The 72-by-72-inch flat layout offers a defined surface for sprawling. Choose it for the low form, while allowing room for the entire circle.
$220
6ft, Dark Gray Microsuede
- Supports a flat or upright lounging arrangement.
- Removable cover and replacement-cover options.
- Its 55 lb listed weight affects repositioning.
- A round lounger is not a rectangular guest mattress.
The full 72-by-72-inch footprint applies when it is flat.
03 / For a lower-priced large foam seat
Big Joe Fuf 7Ft
The exact Corded Plush configuration is priced below the other large named Cosac sizes. Compare its 62-by-51-inch floor dimensions rather than assuming a seven-foot diameter.
$224.99
Signature, Midnight Blue Corded Plush; formerly Fuf XL
- This Corded Plush cover removes for machine washing.
- The maker publishes width, depth and height.
- It weighs about 57 lb and needs periodic fluffing.
- Other cover variants may have different care instructions.
“7Ft” describes an approximate diagonal, not an 84-inch-wide seat.
04 / For another substantial foam option
Ultimate Sack 6000
The maker gives a 60–68-inch range across and a washable cover. It belongs in the comparison, but its name alone is not a reliable room measurement.
Check current price
Complete chair; fabric selection varies
- The filled liner separates from the outer cover.
- The maker specifies double stitching and a child-lock zipper.
- The fully fluffed size varies with use and floor surface.
- A single current complete price was not unambiguously verified.
The listed 70–75 lb weight is a consideration for frequent moves.
Make the choice that fits.
Why the size labels disagree
Cosac describes its 7ft model by diameter. Big Joe explains its 7Ft label as a diagonal and separately lists the floor dimensions. Ultimate Sack 6000 is described as approximately 60–68 inches across. These are different measurement conventions, not interchangeable categories.
Make a floor plan before you buy
Mark the full listed width and depth with removable tape. Leave a route past the chair, clearance from nearby furniture and space for your legs in the position you prefer. The occupied shape can spread differently from the fluffed product, so avoid filling a room right to its stated maximum.
A few useful answers.
Which beanbag has a true seven-foot listed diameter?
Cosac lists its 7ft model at 84 inches in diameter. That is a manufacturer specification; we have not independently measured it.
Are XXL beanbags easy to move?
Large foam seats in this shortlist have listed weights around 55 pounds or more. Their size also makes them awkward to handle. Consider who will move or fluff the chair, not just where it will sit.
