EDIT Sept. 2022 I've had this for 5 years, and it has seen heavy daily use. And I do mean "heavy." I'm about ready to get a new one, as this one's table surface is starting to wobble and sag. Given what I've done to it, I am more than pleased. With lighter use and fewer hours, it should last a decade. I have looked at a tried quite a few "tray tables." In my experience, you get what you pay for. the cheap ones are (not surprisingly) cheap and nasty. This was my wish-list. * Goes down to 23" from tray surface to floor * Does not require that the entire unit be moved to get it out of the way to stand or sit down (this means no wheels, nothing on rollers) * Is built out of heavyweight materials * Unit can be stood on either side of the chair * Stays where you put it * I don't have to remove everything from the table to move it so that I can get into and out of my chair. In other words, I wanted a stable swivel. * I wanted some flexibility in positioning. (Who does not like to rearrange the furniture once in a while?) This tray table was bought for use with my laptop. Most of the chair-side or over-bed table designs have a "lowest height" that was too high for the chair I use. This one is rated to go down to 24", which is only just a bit higher than I wanted.The frame is held in place by the chair it serves, so even if the chair is not massive, it is very firm once you add your body weight to it. It does not move, nor is it meant to move. I am a keyboard basher (as opposed to a light tapper), so it wobbles a tiny bit when I get carried away. This can hardly be avoided in any design that has a surface cantilevered out from a single post, no matter how solid it is. And this is very solid, as these things go. A traditional TV tray had 4 legs and they all wobble like Santa's tummy.The slight wobble is not a bad thing, really, because I am now learning to lighten my fist up a bit. It's a small laptop, so there is room for a mouse, but I mouse from a stiff cardboard sheet placed on my thighs, so it would work fine with my larger laptop, too. The space I don't need for the mouse is adequate to add a large mug, along with a cereal bowl or salad plate. Tray Placement The ability to swivel from multiple joints (360 degrees at the post and 360 on the tray mount), offers almost infinite variability in positioning. You may need to experiment a bit to find the right arrangement with your particular chair size, room placement and ergonomic needs. Frame Placement You can place the floor bar inside or outside the chair legs, on either side of the chair. which changes the distance to the standup-assistance knob (SAK) you can lean on to assist rising. My chair's legs are 27" apart front to back, and the front legs are 25 inches apart. I just now tried placing the unit so that the front legs are the ones sitting on the floor wings, (instead of the ones on the side). This actually works better for me, as it moves the SAK a little closer to my body. This chair is close to the minimum span. I estimate that 23" is about the smallest leg span (side to side or front to back) that the unit will accommodate correctly. It's sturdy enough to eat from and/or drive a computer if not held down by the furniture, but I would not recommend trying to use the SAK unless it is secured by furniture. That floor frame bar can be expanded quite a bit - at least 12 inches, I think, maybe more. So it will also work with much larger furniture designs. Height adjustment I was prepared to live with 24 inches high. However, if you take it all the way down, past the height where the adjustment button is actually in the lowest hole, then it goes to 22.5 inches. Score! From the lowest "official" position it is indeed 24 inches high, and can be raised in 2-inch increments. I REALLY like that I can raise the whole thing so that my little screen is at eye level for reading or watching videos. My vision is poor, so the right height for typing is NOT the right height for activities that are entirely visual and/or mouse driven. Photo A - Shows tray swiveled in very close to hypothetical body (I can't really get it to that spot when I am in the chair as I am an adult with an average BMI, not a Twiggy or a six-year-old). B - Shows tray swiveled so that it is in the same orientation to the chair but placed about 12 inches closer to the camera than it was in A. This is a bit too far away for comfortable typing. C - Shows the entire tray pushed away from the chair giving full chair access to stand or sit. I would guess that it is about a 2 lb push to get the tray pushed away, so even the feeblest can re position it with ease. Moving the whole unit, not so much. See caveat. Caveat The only attribute that some might consider to be a problem is that it is heavy and you need to lift furniture to get it in its permanent place. If you are impaired strength-wise, get help to position or re position the unit. Also, it might require a bit of robustness to adjust the height. The little button is on a strong spring and the tray with tray arm have to be lifted. The tray assemblage that has to move when adjusting the height weigh about 7 lbs. so when you add a bit of friction, it might be a bit heavy for a frail person. I really like the way this thing is engineered. Built to last. So looking at my wish list, I give it a perfect seven out of seven. I'm so happeeee!
