Frequently Asked Questions

How do your pads differ from genuine Knoll replacement pads?
Our pads follow the original shape patterns of the authentic Knoll chairs designed by Harry Bertoia but there are a few differences:
  1. Ours are cheaper. An average price for our seat-only side chair pad is $99. Compare to genuine Knoll pricing that starts at $170.
  2. Ours arrive faster. Even though our pads are made to order and we source some of our fabrics from Denmark, we can still deliver within one to two weeks, three in the worst case. The average Knoll lead time is 8-12 weeks.
  3. Our padding layer is a 1/2" thick sheet of high density foam instead of the injection-molded product used by Knoll. In terms of comfort, it is plenty of padding, but you may notice it is slightly less stiff than a genuine Knoll pad. Think of our pads like finely tailored clothing, the fit improves with time and use.
  4. On a full pad, we don't use matching upholstery on the back side that is seen through the wires, we use a high-quality black canvas instead. This is what we use on the underside of all our seat-only pads as well. Purists may object to this approach but it cuts the amount of expensive fabric in half. If you must have an upholstered back, feel free to purchase a genuine Knoll product at twice the cost.
  5. We don't use toxic adhesives. For seat-only pads, we don't use upholstery glue. We do this to avoid the fumes during fabrication and the off-gasing of the product into your home. This gives our product a slightly looser appearance on the chair but we've found that after the pad has had a day or two to settle into the body of the chair, it looks just like it did back in 1952. Perfect.

Will these pads fit my vintage chairs?
Yes, each pad follows the original patterns of the authentic Knoll chair design by Harry Bertoia so fit is not a problem with original Knoll products. If you are trying to upholster a reproduction (or a "knock-off" for you purists out there...) you should be ok too, they tend to work even if the wires are spaced a bit differently than the original Knoll production models. Please note that the full cover should only be used for genuine Knoll chairs as the proliferation of bad online knockoffs with much larger chair bodies makes the fit an issue. If you have a knockoff/reproduction chair, the full pad upholstery is not guaranteed to fit. Seat pads should work either way.
How long will it take to get my order?
That depends on the type of upholstery you choose. We stock "basic black" vinyl for "seat only" side pads and diamond chairs so those can be in stock and ship right away. But if you choose one of our custom Maharam patterns and want four of them it could take 2-3 weeks to source material and fabricate for your order. "Full" style upholstery for the side chair is made by hand and can take up to 3 weeks once we get the material in stock. Keep in mind these products are made to order, by hand. Quality craftsmanship takes time and some things really are worth waiting for.
I have a child size chair, do you sell pads for these chairs?
We do offer the child-size side chair seat-only pad but not the child-size diamond chair.
Do you offer custom fabrics and colors not shown on the website?
We can do upholstery in just about anything but it takes time and can cost more. Let us know what you want and we will email you a price.
Do you offer leather upholstery?
Yes, we do. We use lamb skin hides that we source for each order from a leather shop in Manhattan's fashion district. We currently offer this option in brown and black leather. Visual appearance of a natural hide can vary a great deal so please request a swatch of our current leathers so you can see what you are getting prior to an order.
I don't know what size chair I have, can you help me figure it out?
Sure, we're happy to help but please check our 'Chair Types' page for sizes and details on each chair first. Chances are you can figure it out from here.
How is your upholstery constructed?

All 'seat-pad only' upholstery is sewn by hand in our New York City studio. These upholstered pads are made from a 1/2" thick foam pad with a black canvas bottom to protect against wire-wear. Side pads have a nylon strap with velcro closures to guarantee a secure fit to the chair. Diamond pads have a front wire that secures the front lip of the pad and a velcro closure at the back to secure the chair.

I have a diamond chair but I'm confused by your "small" and "large" types, why are there two sizes?
This is a frequent confusion. 99% of people have the "small" diamond, sometimes called the "regular" diamond as it was the most popular version. It measures 33" wide (from tip to tip of the "arms"). But there is another much wider version called the "large" diamond. It measures 45" wide from tip to tip. Our hunch is that it is a similar width to the "Bird" chair, in fact, we're pretty sure the Bird is a large diamond with a head on it but no one has ever checked so you'd have to take our word for it.
