What People are saying about Miracle Casters

Received your casters and they seem to be working great.  I can move on the rug!

Eilleen H., Harrisburg, PA



Excellent. This looks perfect and much better than replacing the flimsy chair mat I bought barely a year ago! Thanks, 

Jim T., Apex, NC



Wanted to let you know that I put the casters on my Aeron chair, and omigod they are awesome !!! I have to tell you that I was somewhat skeptical they would do the trick w/ our carpet, but MAN! that chair glides so smoothly now.

So, definitely put it on your web site that the Miracle Casters are perfect for the Herman Miller Aeron chairs. The fit is perfect, the caster slides in w/ a little resistance and doesn't have any problems being loose at all. And the stem is a little longer than the stock caster, but I measured the hole, and there's plenty of space left even above the Miracle Casters' stem.

Thanks again, and I'll be ordering another set (possibly 2).

I just wanted to say "thank you" for the excellent casters and the wonderful service at Miracle Casters. The casters made it so much easier to roll on my desk mat which kept getting indentations that would make it hard to roll after sitting for a while. The casters also solved a problem my chair had with making a really loud "snapping" noise when I would sit in it for a while and then try to roll. . . .  Your service and product are wonderful. . . .

Perfect.  Great price, great product, and I couldn't believe you shipped it UPS Priority at no charge; arrived less than 48 hours after I placed the order.  Very nice surprise.
Goodbye ugly plastic mat!  Your casters went on an Aeron chair, and actually improved an already-excellent product.  I've got a pretty bad neurological condition which causes major pain; the Aeron has helped that, and your casters are little 'miracles' too, making a good product better.
I've successfully ordered goods from the internet for many years, but this is the first time I've felt I should write a company with my compliments.  Keep up the good work!  Many blessings.

I received the casters today and installed them on my Aeron chair. They're great. I have Berber carpeting with spongy underpad backing. The wheels roll very well on it. Also, the chair seat post was making contact with the carpet and damaging it. Now it rides 1-1/2" above the carpet. Thanks for solving my chair problem.

Welcome to Miracle Caster. Miracle Casters are large  chair
casters that offer several advantages over regular chair casters:

Miracle Casters roll more easily over carpet
eliminating the need for a chair mat.

Miracle Casters roll more easily over tile floors.

Miracle Casters raise your chair about two inches.

Miracle Casters are heavy duty casters and well suited for heavy individuals.

Miracle Casters can be useful to individuals with certain types of disabilities, offering an alternative to a wheelchair in some situations.
Order online using the button at the bottom of this page.

Miracle Casters use wheels that are nearly 4 inches in diameter. That's twice the diameter of the cheap casters supplied on most office chairs. Because of their larger size, Miracle Casters roll easily over thick carpet or grouted tile.  Think of the huge wheels on tractors and other heavy equipment. Miracle Casters work on the same principle. The bigger the wheel, the easier it will roll over a soft or uneven surface.

Before you buy a set of Miracle Casters, measure the stem of your current casters. Your stem does not have to be the same length as a Miracle Caster stem, but it must be the same diameter. To measure your caster stem, you must first remove the caster. Grip the wheel firmly and pull it straight away from the bottom of the chair. You may need to wiggle it as you pull. The wheel should come off, along with the stem, when you give it a good tug. 

If it does not come off with a tug, do not strain yourself. Some casters, especially on furniture other than chairs, screw on. Currently, we are not offering screw-on type casters.

Once your caster is removed, measure the stem to make sure that the diameter is 7/16 of an inch. This is the most important measurement. Click here for tips on how to measure the diameter of you stem.

The length of your stem is less important because nearly all office chairs have similar stem lengths that are compatible with the Miracle Caster. Miracle Casters have a stem length of 7/8-inch. These casters can usually be used to replace casters with stems between  -inch and 1.25-inch in length, as measured from the top of the mounting nub.  The end of your stem may be flat or rounded. The two types of stems are interchangeable.

Your current casters may differ from Miracle Casters in that your casters may have a thick plastic neck that makes the casters appear to blend with and be a part of the chair leg. However, this is a cosmetic difference only. Though Miracle Casters do not have this thick plastic neck, they will still work fine, assuming the stem measurements are as described above.

Before ordering, make sure that the seat of your chair can be lowered a couple of inches to compensate for the extra height of a Miracle Caster. Otherwise, your legs might not fit under your desk!

Each caster is rated to carry 130 pounds, which means that a set of five will hold a static load of 650 pounds. Miracle Casters are helpful for many heavy individuals. However, for best results, we do not recommend Miracle Casters for individuals over 300 pounds. 

When used on carpet, each Miracle Caster is guaranteed against failure for 10 years.

Standard Miracle Casters cost $9 each plus shipping. For less than you might pay for a chair mat, you can get a set of five Miracle Casters delivered. 

You will not find Miracle Casters at your local office supply or furniture store. 

Please measure your caster stem before ordering!

Quantity: $9 per caster plus shipping.
                                                 Most chairs require five casters.
