mikibama vs Shintenchi
110″ Boneless Modular Sofa against 105″ L-Shaped Modular Sectional. Both are foam-built couches sold on Amazon; the differences that decide it are footprint, what the seller documents and how each is configured.
THE SHORT ANSWER
mikibama or Shintenchi?
Shintenchi suits a buyer who wants an L-shape with a simpler return path, since Amazon.com sold it at research time, and mikibama suits someone set on a straight velvet three-seater. Shintenchi publishes 104.3″ by 67″, while mikibama gives only a 110″ nominal width, 5.7″ wider and with no depth.
mikibama 110″ Boneless Modular Sofa
110″ nominal width
The 110-inch mikibama listing is described as a three-seat velvet boneless sofa with deep seats, anti-slip treatment and no assembly. That differs from the brand’s better-documented framed chenille sectionals, so construction and policies from the wider catalog cannot safely be applied to this foam model.
- Choose it for: A straight three-seat boneless sofa with a deeper lounge profile.
- Check first: Mikibama also sells framed sectionals; do not transfer their construction or warranty details to this model.
Shintenchi 105″ L-Shaped Modular Sectional
104.3″ L × 67″ D × 23.6″ H; 49 lb listed
This 105-inch L-shape is one of the few in the category sold directly by Amazon.com rather than a marketplace seller, which simplifies returns. Against that, the listing is comfort copy end to end: high-density foam is claimed with no density figure, and no seat height or care label appears anywhere.
- Choose it for: A large L-shape sold directly by Amazon rather than a third-party seller.
- Check first: The listing repeats comfort language without a single measured internal specification. Ask for the foam density and seat height before committing.
DECIDE FOR YOUR HOME
Which one fits how you live.
Pick mikibama if
- you want a straight sofa with no chaise reaching into the room.
- velvet is the fabric you want and you will check the care instructions before ordering.
- you can get the seller to state the depth before delivery, so the 110″ run can be planned properly.
Pick Shintenchi if
- you want Amazon.com as the seller, as it was at research time, and you confirm that on the order page.
- you need an L-shape whose chaise side runs 67″ deep.
- you can accept a listing with no foam density figure and no seat height.
Room and delivery check
- Width: Shintenchi is 104.3″ long and mikibama 110″ nominal, a 5.7″ gap. A 14-ft wall leaves 63.7″ for Shintenchi and 58″ for mikibama; a 12-ft wall leaves 39.7″ and 34″.
- Shintenchi's 104.3″ by 67″ box is 48.5 sq ft, 28.9% of a 12×14 ft room, with 77″ of depth left on a 12-ft side. mikibama's depth is not published.
- Height: Shintenchi stands 23.6″. mikibama's height is not published.
- Shintenchi arrives in two boxes and needs 72 hours to expand. Its 49 lb listed weight is light for a 105″ sectional and may describe one carton. mikibama's weight and box count are not published.
Risks to clear before ordering
- Shintenchi claims high-density foam with no density figure, and mikibama's foam density was not verified. Neither publishes a seat height, so comfort and ease of standing are unknown for both.
- mikibama's better-documented sofas are framed chenille sectionals, so match the 110″ boneless listing exactly before relying on any detail.
- Shintenchi's Amazon.com sale meant standard Amazon returns at research time, subject to the item's own terms. mikibama's seller and opened-box terms still need confirming.
BEFORE YOU ORDER
Questions to send both sellers.
- Shintenchi: what is the foam density, and how high is the seat from the floor to the top of the cushion?
- Shintenchi: is 49 lb the weight of the full set or of one of the two boxes?
- mikibama: what are the depth and seat height of the 110″ velvet sofa?
- mikibama: how does the anti-slip treatment work, and does the velvet cover come off for cleaning?
- Both: does an opened, expanded sofa still qualify for return, and who arranges the pickup?
