Very simple assembly. Was sturdy after all screws were tightened. Be aware that this is particle board so it will bubble up if it gets wet. I learned this the hard way by putting a plant on it that sweat through the pot and damaged it. I have 4 stars because two of the screws stripped in the home because of the cheap wood (I was even being careful not to yet m tighten them too much). Additionally, the screw hole covers were only cheap stickers that started peeling off within 24hrs. Otherwise the product was solid. If you don't mind exposed screw holes then those is a good deal. One other thing to note is that it only comes with 4 square backing pieces to cover 4 of the cubbies, not all 8. I wasn't expecting any but only 4 was a little odd.

Worth the money.

Was surprised with the way it was to be positioned, vertically. It’s perfect for where I wanted it. While it was different to my plan, I love it. It’s a good value for the price. It held bigger totes than I thought, it was easy to put together and seems to be well worth what I paid.
