Question: what are the dimensions for the top shelf?
Document: We bought this recently and it looks awesome in our kitchen! It actually looks more expensive than it was. It only took my husband a short time to put it together. The only downfall, our microwave doesn't fit on the top shelf. But it still works well and gives us some extra storage.
Although it took my husband quite a while to put this thing together, he didn't seem to have a hard time. Included all of the hardware and had pre-drilled holes. The final product is just the right size for our large microwave. Lots and lots of room on the top shelf and underneath in the cabinet.
Fast Shipping ,  Easy to assemble,  Looks very nice,  Works great for our large microwave, we have it in the middle shelf, lots of storage room underneath
Sturdy and looks very nice. Fits under our wall phone. Sturdy shelf in side with magnetic latched door. Very pretty color. Can be found for a reasonable price.
This requires quite a bit of assembly, but all the parts were there and the directions were pretty clear. It looks just as described. I put a small tv on top of it and use it to hold cookbooks and table linens.
We just got this yesterday in the mail. Setup takes about an hour, but it's very easy with detailed instructions. The quality is great for the fairly low price. It fits a standard microwave and we put our toaster over on top. Looks great in our kitchen! Definitely recommend!
It doesn't even fit nicely on the top of the printer cart that currently holds it. I could wish it had casters simply so it's easy to move and clean underneath, but if I want them that bad, I'll figure out a way to do it.I got this in my 2 day prime shipping, and am just waiting for a new door and side to arrive from the Sauder replacement center.Be aware, this box is heavy to handle alone.
That being said, it just fits with no room to give. Maybe it was my fault; perhaps I misread before buying. Either way, my microwave looks like a giant in this thing.My real issue with this item is the quality. I knew I wasn't purchasing some top of the line piece of furniture; I wasn't trying to. I was, though, expecting something a little nicer. It is heavy and the areas that need to bear the most weight are sturdy enough to do so.
We use this microwave stand next to our kitchen table for extra storage of items we use all the time. It keeps us from having to jump up and run into the kitchen.Our microwave is too big to put on the stand, but it's pretty big as microwaves go. A smaller one would work fine on it. We put our telephone on the top, and other things we need.Also nice that this stand matches the Stauder pantry we recently purchased. They both match our oak kitchen cabinets almost perfectly.
perfect size classic look strong and durable easy to assemble even good in living room not just for the kitchen
Answer: The very top shelf is 28" wide and 13 1/2" deep.   The shelf where the microwave sits is 24" wide and 19" deep.  We are very happy with this purchase.
