The worst thing in terms of construction, stay away, I should mention that the sofa, as well as possibly all products of the woodwell company, is Chinese, which means that if it comes to you defective like us, it will be difficult if not impossible for them to fix it for you.
We received it with one pillow wrong (as you can see in the photo, the pillows are 6, for some reason they have different sizes (2) in their corners and instead of coming as 3+3 for example, they came as 4+2, resulting in one not fitting and not going in). After multiple phone calls and after 5 months, they managed to replace it for us, and that is the least they could do.
The sofa also emitted insects like bugs occasionally, and without the seats sinking, it was terribly uncomfortable, the pillows were too far back and put you in an uncomfortable position for your back. After just 6 months, it had made terrible sinkings, without exaggeration, when I sit on it, it feels like I'm in a squat position. If the photo helps, I have placed my knee without much pressure to show you how much sinking it has in various areas.
And a piece of advice for those of you who have issues with your waist/back like me, since I suffered to learn it, go to a store to try out any sofa before buying it, otherwise it's not possible even if you eventually buy it online, go and try it because you can't tell anything from the photos, like this one in the photo looked nice but it's going to be thrown away after 1.5 years of use. Oh, and I forgot to mention that I bought it for 340 euros and not for the 650 they are asking for it now...

Easy to assemble. The legs are screwed in with a suitable screwdriver, no need for a drill. Comfortable and sturdy construction. It is not a deep couch and even someone not very tall will sit almost upright and will not have support on the neck
