we went there after they first opened to get new living room furniture. We were on the fence with 2 sets. We finally decided on one.
3 mpnths after owning it, the foam cushions inside the microfiber cover was shifting. Every single cushion was lopsided with a huge luimp in it. I called to request new cushions. There was no issue since it was within the waranty. HOWEVER, when the cushions came in, it was again only the foam inserts, which would eventually do the same thing.
I called and spoke with the manager, and told him that there was no way I was keeping this furniture set. After some resistance he finally agreed to a full credit. We then went in and got the other set we had wanted. That was 4-5 years ago, and this set has held up well.
Don't back down until you are satisfied. There is not reason year old furniture should be falling apart.
