Can the seat be locked up during use?

The seat has a lock in the vertical position to facilitate walking safely. In the horizontal position there is no lock because it is not needed.

No, it does not lock. You can adjust the height setting to make it easier to balance your weight. I would imagine it would be quite dangerous to have a locking position.

The wheels don't have locking mechanisms, but my chair is on a fairly thick rug and it doesn't move unless I really want it to. I had initially planned to leave the wheels off, but I wouldn't advise it unless you have some sort of protective barrier between the feet and the floor.

Yes you can. But the locking hole is not very large, so a small lock is needed.

Unfortunately I don't think locking mechanism exists for the wheels for this chair. But these wheels are just inserted in the legs of the chair. So if you have something else that fits in the legs instead of these wheels, you should be able to use that.

Yes. It is important to make the clamps very tight. The chair must not be able to move at all.

You should be able to. I've been using it with my son (and seat fully reclined) since about 2 months.

My seats just fold down over the Duha and works just fine. There is no way that I know of to lock it down unless there is some aftermarket gadget.

It's designed to be locked, however, if you leave the top clamp loose, it will spin. I honestly don't think it would cause any damage to do so.

I have one and love it. Very sturdy. But no you can't lock it unless you put chains around it. Otherwise there is no mechanism to lock it.

Yes, it can be used as a seat and the wheels can be locked. My grandmother says it is comfortable.

If you mean can you lock the top and bottom together, the answer is no. There are provisions for a strap to secure the top and bottom.

No its locks into position once you open it all the way,seat being down is just necessary if you want to sit down

You can yes, but because the seat is fixed its very uncomfortable and puts strain on the lower back

This chair cannot be locked while reclining. It can lock, however, in the upright position to prevent reclining.

No, there is not a lock but the chair is quite heavy and requires some amount of force to swivel. You cannot sit and swirl around freely. The chairs are very substantial and sturdy.

You can lock it into place or you can release the latch and lean back - If you are considering buying this chair, know that the wheels break - I bought two of the chairs and the wheels broke on both. Just order yourself a good set of replacement wheels....not a big issue. The chair is very nice and has held up well. I have one of home and office and get compliments almost daily. I hope this helps.
