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.

very nice for the money
Color: Dark Grey, Size: 5 Seat, Color: Dark Grey, Size: 5 Seat
Very comfy. The color is perfect. The back pillows do shift when leaning against them but a throw pillow or two helps comfort. The material is soft. And it was fairly easy to assemble with 2 people.
