I look at several dumbbell rack on Amazon and finally decide to go with the apex 3 tier . very happy with this product . as many item I have receive from Amazon , the box be destroy . not sure what go on at they facility but they be hard on some cardboard ! regardless , all the item need to assemble the rack -lrb- nuts\/bolts -rrb- be in the box and I put it together in about 10 minute . this thing be very well build and extremely sturdy . I have dumbbell pair include 15 , 20 , 25 , 30 , 35 , 40 , and 50 pound on this rack . I would have give this rack a 5 star rating if they have make it about 4 inch wider because I could have stack my 45 and 60 pounder on it as well . regardless , great product . it be like sit you dumbbell on a concrete floor except now I do not have to bend over and pick they up .
