Question: How heavy is the 48" shelf?
Document: Needed a shelf over 48&#34; for my daughters nursery. She has a long name and we were displaying it with wooden letters. Most of the shelves we saw in person were too small. This shelf not only was long enough, but very pretty too!
This is an awesome way to decorate. Looks so much better than a simple shelf. It brings elegance into the room
The shelf is made well and is easy to install. The shelf is made out of MDF and has a nice white finish that can be painted.
Nice quality shelf and looks great on the wall.Mine came without hanging hardware but they were quick to deliver it.Hung this by myself without a problem and it looks great.May buy another one!
I am very pleased with my new shelf. Very easy to install and looks perfect over our bed. The shelf arrived quickly without any damage. Light wieght so easy to hang and is very secure on the wall. I would recommend this item.
I was searching for a fireplace mantle and found that they were rather expensive. Then I came across this shelf and thought the price was right.When I received it I was very pleased, it looks great above my fireplace, and is super easy to install, and since I am renting, it can be easily removed.
The shelf came much quicker than stated. It was very easy to install and looks great. I feel the items I have on it are safe, as the shelf seems very secure. The quality is better than I expected. It is just what I was looking for. I like it so much I just ordered another one.
I really like this shelf. I'm using it as a mantle for my fireplace. Much cheaper solution than having one made. I would've given it 5 stars if it were a bit deeper. As it is now, a wide based bath & body works candle just fits. Great price though!
The shelf was bought to hang over my couch in the living room.....It looks great and was easy to hang. There was damage to one side of the shelf but rather than return it I just touched it up with some brown paint. The person who hung it on the wall commented that it was somewhat bowed in the middle and therefore it took a bit of effort to level it.
I ordered this to put on the top of the beadboard in our bathroom. My boyfriend was skeptical at first but ended up liking it much more than he thought he would. It was easy to install and looks great! I love it and now I have a place for candles and bath salts. It was much cheaper than buying trim to make our own shelf. 100% satisfied and happy!
