Question: What is the total  height from floor to top shelf?
Document: I guess u get what you paid for, the top plank which has 5 tubes that need to be screwed in is drilled with 5 holes and as i began screwing in those tubes, the wood just chipped off. The material doesn't look like wood at all. So now i do not have the top plank, planning to buy a pedestal to put on top to increase the height of the platform. The shelves are well designed but i am scared to put my tv on top of this structure.
The fifth one? When I started screwing it in, the wood around the nut cracked and the tube fell off. Fortunately, the other four are fine, and the TV pushes down on the top shelf, so the tube in question is not going to slip or fall off.
very cheaply and poorly designed. The top and middle shelf are already bowing inwards and I've only had it for a month or so. u can see by the picture, where the metal stands are there are none in the front middle so there is no support..dont' purchase..going to be a pain in the butt to send back.
I know this unit is only recommended for 46 inch and smaller, but my TV is a thin panel and weights less than 70 pounds. The top shelf is rated for 95lbs, so I feel safe.The cabinet doors were a little tricky, but not as bad as some reviews claim.The shelves inside the doors can not be arranged for 2 rows of DVD's to stand upright.
The wood is particle board fairly easy to screw into. The hinges are decent. The top black shelf that the tv sits on is heavy and sturdy. Overall I love the product and it's what I expected some of the parts did come defective like one of the legs but I'm hoping they replace that for frees along with a broken hinge but everything else went together nicely
This is the perfect size and shape for my needs: to hold cable box, dvd player on top wide shelf, printer for wireless printing on very bottom shelf, and a bunch of DVDs tucked inside the cabinets and on the middle shelf. The one thing is that the holes drilled on one side of the cabinet for the hinges did not quite line up properly (were too far from the edge) which affects how you open the door.
I specifically bought this stand because of the large, open shelf below the top of the stand. The silver post shown in the back-center of that shelf is actually located in the very center of the shelf, effectively cutting the usable space on that shelf in half. I made do because it would have been such a pain to return. The hinges are also an enormous hassle during assembly. On the upside it is aesthetically pleasing and does seem to be pretty sturdy.
I've had this for a couple days now, when I purchased it initially my main concern was how much weight the top shelf would withstand.The manual that comes with for assembly indicated that it could sustain a weight up to 80 lbs, but some recent changes to the manufacturing of this piece seems to have improved that. You'll notice in the stock image provided that the middle brace is in the far back, which could easily make for the wood to bow under weight.
I purchased this for my TV. Here is what I use it for:Vizio 42 inch on top with vertical XboxMiddle shelf: modem, router and Vizio Sound bar (which fits PERFECT)Bottom storage: DVDS, Xbox accessories in the cabinetsMiddle bottom storage (no shelf): Epson Printer/scanner/fax fits PERFECTLY!! !it sits between two large bookshelves from target and looks like a matching set!!! very happy with the item!
Looks very nice, and the 53 inch flat screen fits on the top perfectly. Sound bar fits between the top and 2nd shelf perfectly. The instructions were good (readable) with a couple of imperfections (it's a lot easier to attach door hinges *before* putting side panels on.) I took one star off due to a quality issue. The pressed (or whatever) composite boards have nuts embedded in them, so you can screw the tubes in that separate the top and 2nd shelf.
Answer: 21"
