I've bought several things on line, but not from those companies. Way back in the beginning of the internet age, I found a company that made custom sofas. I have an odd shaped living room, with a woodstove in a diagonal corner (so 2 short walls) and a wall with cutouts to the hallway. While we had a sofa for the long wall, we needed a shorter option on the other side of the room, so I got a 52" loveseat in a fabric I chose. I bought a leather sofa from Ikea, but I had visited a store to see what it felt like. We bought our dining room table and chairs on line, that was the scary one as that was a lot of money. All have been great- no issues.
