1. COMAX Boneless Futon Sofa Bed, 59″ Small Low-Profile Floor Couch, Black — Largest listed footprint

Listed details: dimensions 35.4″ D × 59.1″ W × 11.8″ H; item weight 39.7 pounds; material Polyester; color Black. The listing is inconsistent on capacity: the specification field says 220 lb, the bullets say 39 lb.

The COMAX Boneless Futon Sofa Bed is a low-profile floor couch listed at 35.4 inches deep, 59.1 inches wide and 11.8 inches high, a 14.53 sq ft footprint and the largest of the three. The seat height is 11.8 inches and the seat depth is 27.56 inches. The listing says it unfolds to a 59 by 71 inch full-size bed (not queen), uses two high-density foam layers, and ships vacuum-packed with no assembly, though it needs 24 to 72 hours to expand. It is polyester, weighs 39.7 pounds, and the spec lists a weight limit of 220 pounds.

Pros

• The listing states it unfolds to 59 by 71 inches, so the sleeping size is clear.
• Deepest seat of the three at 27.56 inches, which suits lounging.
• No assembly; it ships vacuum-packed in one box, per the listing.

Cons

• Biggest floor footprint at 14.53 sq ft, yet only 59.1 inches wide, so it seats fewer people than the 68-inch couch.
• The seat sits just 11.8 inches off the floor, which can be hard to get up from.
• The data flags a capacity conflict: the spec says 220 pounds but the listing text differs, so check the weight limit on the listing.

Who it is for / who should skip it: Pick it if you want a deep lounging seat that doubles as a 59 by 71 inch floor bed. Skip it if you need seating for three or a higher seat.

2. Erament Loveseat Boneless Convertible Sofa Bed, Folding Floor Futon Sleeper Sofa Couch Bed- Boneless Foldable Couch, Corduroy Pull Out Sofa Bed with 2 Pillows for Living Room & Bedroom — Middle listed footprint

Listed details: dimensions 33.8″ D × 53″ W × 26.4″ H; item weight 21.32 kg; color Black.

The Erament Loveseat Boneless Convertible Sofa Bed lists 33.8 inches deep, 53 inches wide and 26.4 inches high, or 12.44 sq ft. The seat height is 25.6 inches and the seat depth is 24.8 inches, the highest seat of the three. The listing describes soft corduroy over high-density memory foam, reinforced stitching, and a change from loveseat to full-size sleeper. It says the sofa arrives 100% assembled. The spec gives an item weight of 21.32 kg and a weight limit of 500 pounds. The listing excerpts do not state the unfolded bed dimensions.

Pros

• Highest listed weight limit of the three, 500 pounds.
• Seat height of 25.6 inches is much higher than the COMAX at 11.8 inches.
• Arrives fully assembled, per the listing, so there is no waiting for foam to expand.

Cons

• Narrowest at 53 inches wide, so it works as a loveseat rather than a large sofa.
• The listing excerpts do not state the unfolded sleeping size.
• Weight is listed in kilograms (21.32 kg) while the others use pounds, which makes quick comparison harder.

Who it is for / who should skip it: Pick it if you want a loveseat-sized convertible with a higher seat and a stated weight limit. Skip it if you need to seat three people.

3. 70” Boneless Couch, 3 Seater Sofa Couch with Extra Deep Seats 3 Pillows,Corduroy Modern Small Couch for Living Room, — Smallest listed footprint

Listed details: dimensions 23″ D × 68″ W × 20″ H; item weight 21 pounds; material Foam; color Black.

The 70-inch Boneless Couch is the smallest of the three on the floor at 23 inches deep, 68 inches wide and 20 inches high, or 10.86 sq ft. It is described as a three-seater with extra deep seats and three pillows, in corduroy over high-density memory foam. The spec gives a seat depth of 23 inches, a seat height of 31 centimeters, foam as the material and an item weight of 21 pounds. The listing states no weight limit and does not say it converts to a bed. The title calls it a small couch, so it is compact rather than truly large.

Pros

• Widest of the three at 68 inches, the only one described as a three-seater.
• Smallest footprint at 10.86 sq ft despite the width, because it is only 23 inches deep.
• Lightest listed weight in pounds at 21, easy to reposition.

Cons

• The listing does not state a weight limit.
• The listing does not say it converts to a bed.
• Shallowest seat at 23 inches, and the listing calls it a small couch, so the ‘large’ in the keyword is generous.

Who it is for / who should skip it: Pick it if you want the most seating width for the least floor space. Skip it if you need overnight sleeping or a stated weight limit.

What to check before buying large sofa

Be clear first that all three are boneless, low-seat foam couches, not framed sofas, so ‘large’ here means width and seat depth. Rank width first: the 70-inch model is 68 inches wide, the COMAX is 59.1 inches and the Erament is 53 inches. For a three-person couch, only the 68-inch model has the width, though its listing does not state a weight limit.

Second, compare footprint against the room. Depth times width gives 10.86 sq ft for the 68-inch couch, 12.44 sq ft for the Erament and 14.53 sq ft for the COMAX. The COMAX is the biggest on the floor but only 59.1 inches wide, because it is 35.4 inches deep.

Third, check seat height and seat depth. The COMAX sits 11.8 inches off the floor with a 27.56-inch seat depth, the Erament sits at 25.6 inches with a 24.8-inch depth, and the 68-inch couch lists 31 centimeters with a 23-inch depth. If getting up from a low seat is hard for you, the Erament’s 25.6 inches is the highest listed.

Fourth, decide whether you need a bed. The COMAX says it unfolds to 59 by 71 inches, and the Erament says it becomes a full-size sleeper without unfolded dimensions in the data. The 68-inch couch does not state a bed mode.

Fifth, read the weight limits carefully. The Erament spec says 500 pounds and the COMAX spec says 220 pounds. The COMAX also has a flagged capacity conflict between its spec and listing text, so verify its limit on the listing before you rely on it. The 68-inch couch states none.

Finally, plan for delivery. The COMAX ships vacuum-packed and needs 24 to 72 hours to expand; the Erament says it arrives fully assembled.

Worked example: fit math for these three options

This worked example is our own planning arithmetic from the listed dimensions, not test results. The wall length and walkway width are assumed example values; replace them with your measurements.

Wall example. Assume 84 inches of clear wall.

• COMAX Boneless Futon Sofa Bed: 84 − 59.1 = 24.9 inches spare; centred, 12.45 inches on each side before trim, plugs or curtains.
• Erament Loveseat Boneless Convertible Sofa Bed: 84 − 53 = 31 inches spare; centred, 15.5 inches on each side before trim, plugs or curtains.
• 70” Boneless Couch: 84 − 68 = 16 inches spare; centred, 8 inches on each side before trim, plugs or curtains.

Walkway example. The US Access Board gives 36 inches as the minimum clear width for an accessible route. That figure is a yardstick, not a rule for private homes. To keep 36 inches clear beside each product, the walkway between it and the opposite obstacle must be at least 36 inches plus its depth:

• COMAX Boneless Futon Sofa Bed: 36 + 35.4 = 71.4 inches of total path width.
• Erament Loveseat Boneless Convertible Sofa Bed: 36 + 33.8 = 69.8 inches of total path width.
• 70” Boneless Couch: 36 + 23 = 59 inches of total path width.

Footprint. Depth × width, converted at 144 square inches per square foot:

• COMAX Boneless Futon Sofa Bed: 35.4 × 59.1 = 2092.14 sq in, or 14.53 sq ft.
• Erament Loveseat Boneless Convertible Sofa Bed: 33.8 × 53 = 1791.4 sq in, or 12.44 sq ft.
• 70” Boneless Couch: 23 × 68 = 1564 sq in, or 10.86 sq ft.

Mistakes to avoid

• Expecting a framed sofa. All three are foam boneless designs with seat heights from 11.8 inches to 25.6 inches. Do not buy one expecting standard sofa seat height or arms.
• Reading footprint as seating width. The COMAX takes 14.53 sq ft but is only 59.1 inches wide. The 68-inch couch seats more people on 10.86 sq ft.
• Trusting one weight limit without checking. The COMAX spec says 220 pounds, but the data flags a conflict with the listing text. Verify on the listing before relying on it.
• Ignoring expansion time. The COMAX needs 24 to 72 hours to expand after unpacking, so do not plan to use it the same day.

Frequently asked questions

Which of these is widest?

The 70-inch Boneless Couch is widest at 68 inches and is described as a three-seater. The COMAX is 59.1 inches wide and the Erament is 53 inches. Width matters more than footprint if you want to seat several people.

Do these fold out into a bed?

The COMAX listing says it unfolds to a 59 by 71 inch full-size bed (not queen). The Erament listing describes a change to a full-size sleeper but the excerpts give no unfolded size. The 68-inch couch listing does not mention a bed mode.

What are the weight limits?

The Erament spec lists 500 pounds and the COMAX spec lists 220 pounds. The COMAX data also shows a conflict between its spec and listing text, so check its limit on the listing page. The 68-inch couch does not state a weight limit.

Are these really large sofas?

Not in the framed-sofa sense. They are boneless foam couches with footprints from 10.86 to 14.53 sq ft. The 68-inch couch is the largest in seating width, but its own title calls it a small couch.
