These are pretty good shelves, but there is no way the particle board will support 800 lb. These are not as heavy duty as the ones I bought from Sam's before for a similar price, but that was a long long time ago. Overall, I have no complaints.

Great price for a great rack. Very sturdy and uses metal interconnect pieces where other brands use plastic. I'll be ordering some more for the garage and basement soon!

I have been very pleased with this 5- shelf rack. I like that it is 4 ft wide and the shelves will easily hold a lot of weight. It was easy to assemble and put in place.

Awesome shelving. Snaps together quickly. Strong, durable, well-made and a nice addition to basement storage area. The unit is not over big yet the shelves hold a lot of items and storage bins fit great!

Great durable shelves, perfect for garage or basement storage containers on adjustable shelves; easy to assemble and good quality. We even ordered two more!

Works at least as well as anticipated to organize my garage - would buy again. The pickup process from the store was not as fast or smooth as I would have liked.

I purchased this for our office to hold inventory of promotional items. The price was great and it assembled quickly. I purchased a second one because the first was so nice.

Perfect for the garage shelves. Very sturdy and fits large totes easily. Adjustable shelves helps you manage different box sizes. Only downside i had was the wood slabs were broken in shipping but Sam’s team refunded.

Easy to put together once you get in the groove. They look nice and hold a lot of stuff. I love the solid shelves. I did have trouble getting one of the shelves to fit in and cracked it.

This is the 4th shelf unit we’ve purchased after the first purchase for our basement we were sold! Since then got another for the basement one for the garage and a fourth for my shop. Really nice shelves sturdy and deep. Easy to assemble.
