An okay sectional
Color: Dark Grey, Size: 5 Seat, Color: Dark Grey, Size: 5 Seat
I want to give my honest review of this couch. One significant difference in the actual couch vs the photos here is the back of the couch is actually much thinner than in the photos. It’s made with metal framing that is very thin covered in fabric with no sort of padding. Also, the back of the couch does not angle back far. Which makes the couch pretty uncomfortable, as your back is up at almost a 90 degree angle.
The quality of the couch overall is good. It was easy to assemble and I didn’t really run into any issues in that regard.
Like others have said. The cushions are quite thin and also not super soft. The couch is also quite low to the ground, so if you’re looking for that oversized super soft couch, this probably isn’t the one.
I do love the pull out bed/chaise which is super nice, ans the storage is great too. For the cost of the couch I think the quality and comfort are good.
I don’t love it, I don’t hate it.

Versatile and easy to use
Color: Dark Grey, Size: 7 Seat, Color: Dark Grey, Size: 7 Seat
This couch was great for the price! Came in about 5 boxes with instructions in each box and the necessary parts for each piece in the corresponding box. It took my husband an afternoon to put it all together and he said it was very easy.
The back cushions attach by velcro which is great in some ways but in others not so much. Our cat likes to lay on the back of the couch and that has caused the cusion to indent and pull away from the velcro. We've only had the couch a week and that cushion is already not wanting to reform.
The pull out bed is very easy to use even with my back issues.
The storage is fantastic.
Every cushion comes off for easy washing.
Cushions are firm and comfy.
All in all 100% worth the money so far.

Favorite Couch Ever! 💗
Color: Dark Grey, Size: 7 Seat, Color: Dark Grey, Size: 7 Seat
This couch far exceeded my expectations. It was on sale for $750 when I purchased it which is a steal! The cushions are EXTREMELY soft and comfortable. Its appearance is very modern and saves up so much space! The height is perfect and it easily folds back to make it not like a day bed. Personally we leave it like this especially with a baby because it gives us a lot of room to stretch out and again SUPER COMFORTABLE. The fabric is phenomenal and very easy to clean! 10/10 definitely recommend! Would purchase again! The storage area is perfect for pillows and blankets as the ottoman can hold things as well as the chase WHICH can be accessed while the couch is in “day bed mode” as I say. Nothing but good things to report!

Nice couch for the price
Color: Black, Size: 7 Seat, Color: Black, Size: 7 Seat
Nice and firm I was able to put it up by myself in about three hours. It is really cute The material is soft. I really like it. It was super easy to put together. It came in 4 different boxes, I was worried because people said they got the boxes on different days luckily, I got the whole couch the same day and put together that night. I’m happy with this purchase. Can’t wait to sit on it and watch TV. I just wanna give it a few days to let the seat cushions recover.

Love the storage and pull-out
Color: Dark Grey, Size: 7 Seat, Color: Dark Grey, Size: 7 Seat
The size is great and fits nicely in the corner without feeling too bulky, but still has plenty of seating. The dark grey color looks clean in person and matches my space really well — not too light, not too dark.
The pull-out part is honestly one of my favorite features. It slides out pretty smoothly and turns into a big lounging area or bed. I’ve already used it to relax and watch TV and it’s really comfortable. The storage compartment is also bigger than I expected — I can fit blankets and a few extra things in there easily, which helps keep everything more organized.
Comfort-wise, I’d say it’s medium-firm. Not super soft like a cloud couch, but still comfortable enough for everyday use. The cushions seem to hold their shape pretty well so far.
Assembly took a bit of time and it’s easier with two people, but overall it wasn’t too complicated. Once it’s set up, it feels pretty sturdy.
If I had to nitpick, the cushions do shift a little after sitting for a while, so you may need to adjust them occasionally. But for the price, I think that’s pretty normal.
