How much weight can it hold? I need a riser for my iMac.

Definitely not recommended for an iMac. Laptops are okay, iMac seems too heavy

Mine weighs in at around 40 lbs...which I thought was rather silly heavy. Would not trust any plastic stand to hold 80 lbs, but it may work. Having trouble coming up with any computer that could possibly be that heavy, by the way. While I have no idea what you have to make it that heavy, would suggest you make a custom stand...fairly easy to make from wood, by the way.

I don't know how much weight it will hold but I have a full size PC & it has room for a larger unit. It seems to be built pretty well. I have no complaints & I recommend it.

1" - this is the best stand ever. very strong. seems like it should bow in the middle but it doesn't budge. we have a 27" imac on it.

A 30" monitor, laptop and 6 painfully heavy books on it and it hasn't warped any over a year. However, those are spread out so a lot of the weight might be over the legs of the riser. My impression is that it's pretty tough for a desk riser. It's unlikely to warp or bend under the weight of a 46" TV.

I have a 17" Toshiba laptop on it and it just fits so I think your Mac's going to be too large for this stand. Unless you don't mind the laptop extending over the sides. As far as weight goes, this stand is very sturdy.

Although I have no idea how heavy your 21.5 is, I have a 2011 iMac 27 and I'm certain this arm cannot hold it up. In the short term "maybe" it could, but I wouldn't trust it to carry the load over the long term. Additionally, I don't see how this arm could interface with the back of the iMac, which is designed to stand on it's own mount precisely because it is a bit on the heavy side, as well a bit off balance without the stand attached. I'm sorry I can't be more helpful. MIKE

The LapTuk Pro Stand which I bought 2 months ago raises my iMac 2 1/2". An excellent product.

Have no exact figure - but the desk is very sturdy and can hold an iMac and probably more. It's solid as can be! Hope this is helpful. Lars Eriksson

I installed a 2009 or 2010 Imac 27" and did worked. It is good arm, just the piece to tight/loose the spring that give the right tension to the arm in relation of the weight, is week related to the pressure you have to make when you adjusted and in my case broke. I have to returned but I am thinking in get it again and be very careful and slow when you tight it

The cable is made of carbon-strengthened steel. I'm sure there may be some bolt-cutter out there that could do the job, but not your ordinary bolt-cutter. I can't think of a safer solution other than locking your iMac up in a safe.

Yes. It should be plenty strong enough. We have that size monitors on them and they easily could accommodate the iMac additional weight.

Yes, the top can hold absolutely flat. I've been using it for my Mac Pro 13" and a few times for 24" flat screen monitor at both indoor and outdoor gig. I just needed to dub tape the legs of the stand on cement floor, as the ground wasn't even. I'm very pleased with the quality. Shipping was great too. It arrived few days than I expected.

Mac 27" support is great. No sag. The structure of the stand is very sturdy and the weight is no worry. No worries.

If it is the "thin" version, maybe, but it definitely did not have the ability to hold my thicker 27 inch iMac any higher off my desk than the stand that comes with the iMac. If you are willing to spend more, have a look at the Innovative 7500-hd-1500 Heavy Duty Deluxe Flat Panel Radial Arm. It is positively bomb-proof and works great on my standing desk so I can lower or raise the computer to any height I want and it stays put.

It supports my wife's 27" iMac just fine. I was concerned and was thinking of making a wooden block that could act as a leg in the middle of the back but it has not been an issue.

I think it's sturdy enough to hold you iMac. I have a monitor on the top and keyboard on the bottom.
