I just received the shelf today and it took my husband and I about 30 minutes to set it up.  It appears to be super sturdy.  I have it in my dining room and have our plates, platters, wine glasses etc. displayed, and it appears to hold really well.  We bumped into a few times to see if it would tip and it stood strong.  I like that the shelves are screwed into brackets adding another layer of stability.  No 5 star because the wood is a bit more grey than brown but I might just add some stain to darken it up in the future.  I am very happy with this purchase.
