First off a huge thank you to everybody who contributes here. This is a phenomenal resource for piano info and has helped me a lot. It helped me decide on my Kawai ES8 and later, the mp11se.

Now, my situation/question:
I just purchased the K&M 18810 (omega) stand to use with my mp11se. (Before this stand, I had a sort of shelf setup that was solid but kind of unsightly and completely inflexible. I would prefer not to do that again since it was built into the wall and could not be moved.)

The stand is positioned either on the lowest setting or near-lowest. There is no wobble left to right, but considerable wobble front to back. (A little wobble when I move it just to test, but big wobble during a Rachmaninoff piece.) There aren't any troubleshooting notes in the instructions, and based on nearly everything I have read on the internet about these stands, it should be rock solid.

What should I fiddle with? I am going to try and tighten the knobs when I get home, but I am unsure what else to try.

[I used the K&M 18953 with my ES8 and know there is the 18950 that would fit the mp11se. My only beef with those stands is leg clearance. It was always a struggle with the 18953.]

You're sure the feet are solidly and evenly on the floor? None of them are even slightly above the floor? If you have it sitting on a soft surface like a rug or a carpet maybe it's just sinking into the nap or the backing.

The feet are not sliding at all on whatever floor covering you have it on?

I have my MP11SE sitting on the 18810 Stand and there is basically no movement at all. Are all parts assembled the right way? The supports on the top must be mounted in the same direction as the feet, as they are not the same length on both sides.

Well I would say it wobbles a bit front to back but is very solid side to side.

I think they should have had a gusset on the base between the legs and the vertical piece.

I never notice any wobble when playing.

Just sold mine but it was rock solid - even when I had a VPC1 on it which is quite heavy - so it is not an inherent defect.
Which part is moving about ?

Thanks, everybody.

Feet are not sliding. Floor is tile and the feet are not on any grout lines.
It is assembled correctly.

The piano is moving front/back when I play hard and fast. Playing light or slower seem to be fine.

We have just decided to add a rug to the room to help with acoustics, and the stand may end up needing to rest on it. This is probably even more troublesome.

I can only report my experience with the same stand in conjunction with the Kawai ES 920. The stand stands flat on the floor. Makes a quality impression, adjustment options completely sufficient. No wobble, no yielding under pressure

Is it the joints in the stand wobling or just the very top part that the instrument sits on ?

The legs should be pretty tight in the outer tubing once the large height screws are tightened. I have no wobble on mine, and I also have a second tier keyboard on top.
Are you sure it's not the keyboard wobbling on the horizontal stays. It's possible the stays could be slightly misaligned? Look horizontally to see that they are parallel.
I've in the past had some wobble if the keyboard is placed with one its the bottom base screws sitting on the rubber feet needing some sideways adjustment.
I'm sure you've checked all these things, but thought I'd list them anyway :-)

No, I haven't actually! I have had to wait for my husband to help me move the piano to and fro, so no troubleshooting has happened yet. We hope to empty the room and reassemble it with the rug tomorrow, this time going through every screw on the stand to make sure it is tight and correct.

I'm sorry that I'm not being specific enough. All I can say is that the piano feels like it is bouncing around once I really start playing. So the piano itself gets a bounce going in the forward/back dimension. It does not seem like the stand will collapse, but it is quite noticeable and detracts from the experience. I can ask my husband to watch it tomorrow while I am playing to see if he can provide more helpful guidance.

A video would perhaps be helpful for understanding

Yes! Exactly that video. The oscillations/bounce/wobble is front-back and is worse without the added straps. Considering it does not fully go away with the straps, I might have to consider a different stand.

The thing that keeps perplexing me is that there are *so many* reviewers and players who comment on this stand's stability. So either there is something up with *my stand* (assembly, location on floor, individual defects) or piano players are all unique and perhaps most of those reviewers aren't playing very hard. (Or both)

Thanks Quatschmacher for digging up that video. It's good to know I am not the only one!

Now, onto getting the hubby to help me lug my instrument around so we can further troubleshoot.

I would stop "troubleshooting" it and return it.

Get one that works.

Sorry if I add to your confusion, but I have the exact same setup you have (MP-11SE + K-M 18810) and had it for maybe one year. And it's allways been rock solid AFAIK. I usually don't bang the heck out of it when playing, but seeing your post I tried to rock it in all directions, but - won't wiggle a single mm.

Suppose you might have a lemon. Just return it if you can't find what's wrong.

I suppose it could be variations in the machining tolerances between batches etc. The horizontal stays have cutouts to avoid any movement when tightened underneath. I do have a slight amount of movement of the legs with respect to the outer verticals, but I have to deliberately rock the stand itself pretty hard to get a noticeable wobble. I have 2 of these Omegas and both are acceptable to me. Perhaps a Z type stand might suit better, as there is no back to front wobble by the design with its downward force leveraging against the joints.
The one thing I've always complained about with the Omega, is the second tier, when there isn't much weight on it. The screw holes are quite sloppy, and the angled stays rock from back to front, if the mount is closer to the middle. But I digresses from your concerns, sorry :-)

I’m using a Yamaha LG-800 stand with my MP11SE, which solves the front-to-back rocking, but has its own problems with side-to-side motion. Annoying for a really pricy stand. Should’ve been made with two cross braces. My old Nord was rock solid with its stage legs. I really hope Kawai makes bespoke stage legs/stand for any MP11SE successor.

I have an onstage 7350, the omega stand is steadier

I’d build a stand out of wood if the omega is moving too much.
