Customer Reviews
Overall rating: 4.9 / 5 from 162 reviews.
Just added this corner seat to our existing M1 set, and it totally transformed the living room. The low-profile design keeps things airy, and the foam remains firm after weeks of use.
It completes the sofa. Perfect to cozy up.
Great sofa.
I haven’t received the rest of my sofa. All I have is the corner. 🫤. It looks kinda sad sitting there all by itself. It looks more like a foot stool.
Bad product. No quality control. Every piece I bought is a different resting height and firmness. 0/10. Will be warning everyone about this brand.
This is the perfect addition if you’re looking to turn your sofa into a sectional, remember the additional seat for equal space on both sides.
Took a long time to get it but it was worth the wait!
So happy with the flexibility and modern look
Perfect piece to complete my couch!
Ordered the corner section as an expansion to my sofa and it is great! It's a bit firm once you adjust, it is perfect. Everyone who has sat on it in my house has said the same thing and once they leave, they say they miss it. Would recommend if you're looking to expand!
As an Airbnb host, I appreciate the modular design that lets me switch up layouts between guests. The eco-friendly materials and spill-proof fabric are perfect for busy rentals.
My back feels supported but not stiff on this sofa.
It’s stylish yet practical for everyday living.
Beautifu, clean modern lines, and comfortable (with pillows!).
We are a household of two big dogs, and one toddler, and this corner piece has survived all of them. The pet friendly performance fabric repels slobber and paw prints, and a lint roller handles the rest. When we host Sunday football, the corner becomes the prime seat because you can drape a leg and lean into the back without any wobble. I moved the sofa twice to rearrange the room, and the easy to move upstairs packaging from delivery day is still sitting in our garage because it was compact and tidy. The only mini issue was waiting overnight for the foam to fully fluff, and by breakfast it felt perfect. We love the lifetime warranty for peace of mind too.
My dog love it, it's his corner
It’s a surprisingly cozy spot for morning coffee.
The vacuum-sealed packaging made setup stress-free.
Great couch and great service!
Great item!
We bought the M1 Corner Sofa Seat to finish a U shape for the basement den where my teenagers watch sports, and it is now the most fought over spot during game days. The vacuum sealed packaging was impressive. I could not believe a full corner could arrive so compact, and the foam popped back with no creases by the next morning. I like knowing the company uses a condensed packaging process so the boxes are lighter and neater to deal with. The corner gives a perfect backrest for side sleepers during late night marathons, and the anti slip bottom means the arrangement never drifts on our rug. There was a minor three hour delay on delivery due to weather, but the final comfort was absolutely worth the wait.
We’re a family with two toddlers, so durability and easy cleaning are a must. The performance weave repels spills effortlessly, and the sofa is perfect for families like ours. With the corner piece, we’ve created a big U-shaped setup in the TV room.
We are newlyweds in a one bedroom, and the space saving design of the corner seat changed how we use our living room. It frames the balcony doors without blocking them and makes our small table feel intentional instead of floating. The comfort engineered foam settles quickly after you stand up, so it never looks slouchy. We had a slight delay of a day because of a regional carrier issue, but customer service proactively emailed updates. I set everything up by myself while my spouse cooked, and there were zero tools involved. The low profile silhouette makes the room feel calm after long workdays. Now breakfast on Sundays turns into a two hour lounge session, which is our favorite new ritual.
The modular design means my sofa feels new every time I rearrange. The corner seat was key to making my space feel complete.
The zip modular connectors hold the piece securely in place with the rest of the set.
It’s the perfect spot to relax after work with my tea.
Super quick assembly. I just opened the box, let it expand, and connected it to the rest of the set in under 10 minutes.
We added the M1 Corner for our family room upgrade after baby number two, because we needed a safe, low profile corner where our toddler would not tumble off sharp edges. The pet friendly performance fabric has already shrugged off applesauce and a rogue marker swipe. The SmartFoam feels supportive in the back yet soft on the seat, which makes nursing at 3 a.m. less of a chore. It was nice to see the fabric is Oeko Tex certified and the whole thing is spill resistant, which takes stress out of snack time. The color looks true to the photos under daylight. The foam took about 24 hours to reach full plushness, and then it settled into that sweet spot between soft and firm. Customer service answered my sizing question in minutes, and the corner module completed our L shape perfectly.
This corner piece really completed our sectional perfectly.
Being able to add more pieces later is a big plus. I had the sectional and bought the corner to complete the set. love ittttt
I had a small delay in delivery but it was worth the wait.
The perfect piece to finish off my corner Sofa! Ties it all together. Incredibly comfortable.
I am a grad student sharing a small urban apartment, and I bought the corner piece to create a study nook that doubles as a nap zone. The space saving design is real. The seat height is lower than the hulking sofas I grew up with, which somehow opens up our tiny living room and makes it feel calm. When I measured, the corner dimension fit right into a 38 inch gap with a few inches to spare, which felt like winning Tetris. It is firm enough that I can sit cross legged with my laptop for hours, and the ultra soft fabric does not make me overheat. I noticed the low profile makes the whole room read wider, and that is exactly what we needed.
The zip modular connectors make it easy to expand or rearrange whenever I want. I’ll probably buy more corner modules, maybe even the full set.
My roommates and I finally found a couch that truly fits our open-plan living space. The corner piece zips in snugly, and the fabric holds up nicely against daily wear.
Spill-resistant fabric saved me during snack time.
Perfect for my small workspace, the M1 Corner makes lounging during breaks more relaxing. Ergonomic, supportive foam gives my back relief without feeling stiff.
I love that this piece is lightweight yet sturdy. Moving it around to create new seating arrangements is hassle-free. Also, the vegan smart foam feels surprisingly luxurious.
Recently married, and this modular system fits our evolving living room perfectly. The contemporary look and easy-to-clean fabric won us over immediately.
