WOW, this shelf is making clutter disappear, b/c I bought smaller tubs like 28 qt Sterilite containers which nicely fit multiple ones per shelf (I chose to use more smaller containers instead of larger plastic containers to keep things more organized). Unless you NEED to be able to consistently wheel the shelving around I'd recommend no wheels, as they sit nicely on the floor, you could put the four bottom spots on those little carpet or floor protectors but I have slid mine across hardwood floors with no problem. Also, the weight capacity is significantly increased withOUT the wheels. A little pricey, but sure beats the many times I've put together mental shelving for storage and spent hours when this took 5 minutes. The hardest part? Getting the 40# boxed item into the location I wanted it, and then figuring out which end was up (much easier if you figure this out first)! Am waiting to get more, but will be getting more.
