Question: Do the wheels lock tightly?
Document: Like the size and how functional it is, but it not sturdy, I have it next to a wall with the wheels lock and it still moved so much I can't cut my steak on my plate without spilling my wine.
This table was very easy to assemble and it's very practical.The instructions are clear, the holes are all in the right place and sooner than you think, you'll have a nice sturdy table.My advise though is to put it against the wall. Even tough you can lock the wheels, If the table is not against the wall  it's very likely that will move around a bit while you're using it.
This is a surprisingly sturdy unit, assembly was not difficult. Looks very nice, and does what we need it to do- serve as a pub table/kitchen island in a small space. I like the way the stools tuck away underneath.The only minor quibble is that the wheels are supposed to lock, so the table doesn't roll when the cats jump on it- and this feature doesn't work too well. The wheels do move a bit, and the table does get repositioned.
The wheels can allow it to move about and it can lock in place for a permanent spot in your kitchen or dining space where ever it may be! The small drawers hold napkins and placemats, and utensils for extra storage.It's also nice to move it away against a wall if you need to have the room and just use it as a small buffet side table.We had no problem putting it all together - and it was delivered much faster than we thought.Thanks again Amazon -
I like how it has wheels so I can easily convert it from the small breakfast bar to the drop-leaf table.
...and its also a great value. I dont use the wheels that were provided and its still perfect. Solid wood.
Table is good quality and easy to assemble. expanding and contracting of the table is effortless. Price was very fair. My only concern is the durability of the plastic wheels it rests on. Overall I am very happy.
Not, as a result of my assembly ability.My suggestion, if you buy this, screw in the table top to the legs first, to make sure it's straight and save your packaging.Also, it wobble when you're trying to cut your dinner. But then, the thing is on wheels.
This little table looks great was easy to put together,and with the wheels stores easy or moves where I need it. this table is great for the small apartments, or just an add work space.The table is very strong, and sturdy. I love it and use it all the time.
Like this product very much. We use it daily. The only problem we have with it is that when folded and in place is hard to move around. The wheel (5th one) on the support for the extension does not move smoothly like the other wheels do. This is reason I'm not giving it a 5 star rating. Thanks
Answer: Two wheels lock tightly enough to prevent unnecessary movement, but if you push it hard enough, it will slip just like a table without wheels.  Ya' gotta use a little common sense.  If you unlock the wheels, it rolls nicely as long as you steer it where you want it to go.  That's good for parking the table out of the way when you don't need it, but not for rolling with food on it.  It's not a serving cart.
