Great for pre-teen or teenager.
Style: White, Style: White
Nice gift for my 10 year old. It took abt 1.5 hours to put together for a handy guy. It was small enough to go into the corner of her bedroom. There was no damage to the wood, no missing parts. Will probably last 3, maybe 4 years im assuming. Just what she needs for now at a great price. Would recommend.

Excellent quality
Style: White, Style: White
Beautiful vanity. Great quality made of sturdy wood. Looks expensive. Was easy to put together because it had step-by-step instructions. It took me a long time because I did it by myself, but easy. The only thing that did not look nice on it was the silver screws showing on the outside and they just give you little white paper stickers to put over them. Would have been better if the screws and bolts would’ve came colored white to match the vanity. I will paint them white myself, but that’s the only thing that didn’t look nice on it. The rest of it is very nice. Highly recommend for anyone to purchase! My granddaughter will love it!

Beautiful Vanity
Style: White
It’s a very nice and spacious vanity. It definitely took a while to put it together but it was worth it in the end. It comes with everything all the pieces were labeled. I love the mirror and the lights. It comes with three different settings for the lights. It’s definitely worth buying.

long building process
The package came very quickly but the box was very damaged. Thankfully, nothing was broken and all the pieces were in tact but the white styrofoam pieces came out EVERYWHERE! (so be careful and make sure you build in a bigger space). It took over 4 hours with 2 people and the directions were a little confusing, especially when it came to installing the lights around the mirror, but after awhile it all came together. It is not the sturdiest vanity but it’s very nice looking. Only thing I wished for was a +/- dimmer for the light settings!
