I've never had any issues with any parts of these chairs. They fold up nicely and stay that way. The side tables are an excellent option as well.

It is sturdy. I have had my 50" lg on it for almost a year now. Just make sure you tighten the locking screws good or it could wobble. The doors are cheap plastic and I didn't use them. It looks better without them.

I could see where you could damage door knob if you don't allow about a quarter of an inch margin before you lock it in place. It mentioned that in instructions.

Haven't experienced a problem with the locking system. Plastic is very thick, & sturdy. Given the correct size for your waist, the velcro is strong enough to keep the belt locked in place even when lifting heavy. I also own a heavy duty leather lifting belt as well, but this one is more comfortable because it doesn't pinch or seem to cut into my waist when I bend over. I also agree with the previous comment that if you plan to lift heavier than 500 lbs, you may prefer the security of the leather belt.

Yes, the bracket is a sturdy metal bracket. The tilting knob is also sturdy, I don't worry about slippage.

No - that is why I chose it over a replacement steel knob, even though the steel knob will neve break and this one can if you drop the lid.

It does slide very slightly but has not interfered with my use of the product. No trouble with the lock so far.

Once this unit is completely assembled, the knob really should not be able to be removed. It should remained tightened, or the knob wil become too loose, if taken on/off. We have been using the table for various purposes since obtaining it and find it to be very sturdy and versatile, with the drawer and shelving.

There is no positive lock but on mine the hinge is very tight and does not swing easily. I am enjoying using mine.

If you tighten the lock adjustment knob it stays true. I have noticed that it isn't the most positive lock, to it doesn't seem to affect performance at all. This is after 8 years of fairly heavy use.

There isn't a knob. On each side there is a clip, I guess you could call it, that flips up and down. There are holes along the side rail where the crossbar slides...that clip locks into those holes to lock the bar into position.

No after a few seconds it automatically locks at least I haven't found a way to have had it for 4 months it's a great boor knob

No. It has a smaller disk shaped thing on the knob. You have to turn it to lock and unlock it from the inside and you have to use the key to lock or unlock on the outside.

Love mine! The knobs lock in place at whatever you set them to. They're not prone to loosening on their own. Set it and forget it!

The knob is strong with good grip; it works fine. If you prefer a metal knob, you can get a modified Progress known as Mergress.

No, unless you turn the lock on the inside, the door knob remains locked. As for having them keyed alike, I cannot answer that one. We purchased two knobs and have not re-keyed them. We have been very pleased with these knobs.

It is easy to install. I removed the old knob and installed the new lock. You have to drill one hole in the door but they give you a template to male alinement easy. I have had it for about 1 year and it works well.
