A Z-frame with its figures

AODSK AS-ZK

A Z-frame stand that publishes both its adjustment ranges — height and width — and assembles without tools. It is the cheapest Z-frame on this shelf, and it has a wheeled twin two dollars dearer.

AODSK AS-ZK Z-style adjustable keyboard stand

AODSK AS-ZK

A Z-frame stand that publishes both its adjustment ranges — height and width — and assembles without tools. It is the cheapest Z-frame on this shelf, and it has a wheeled twin two dollars dearer.

Frame
Z-style, stated heavy-duty. Another page on this shelf sets out why a Z is steadier under weight than a single-braced X (maker’s bullet)
Height
21.2 to 32.4 in — 54 to 82 cm (21.3 to 32.3 in) (maker’s bullet)
Width
21.8 to 35.2 in — 55 to 89 cm (21.7 to 35 in), stated to take 61 to 88 keys (maker’s bullet)
Assembly
No tools required, stated quick to set up and adjust. The only stand on this shelf to say so (maker’s bullet)
Wheels
None. The same maker sells this stand with locking wheels as AS-ZKW, two dollars dearer — and that listing publishes neither of the two ranges above
Load rating
AODSK puts nothing in writing on this. Another page on this shelf states the rule plainly: where a maker publishes no load figure, this site does not invent one. Five of the twelve stands here publish one
Retention
AODSK puts nothing in writing on this — no straps, no padded arms, no non-slip caps are mentioned
Manufacturer reference
AS-ZK
Weight
4,536 g (160 oz) in the product record, which is 10 lb exactly — a shipping figure rather than a weighed stand. Nothing here is ranked on it

  • The only one of the two AODSK Z-frames that publishes its height and width ranges at all
  • Assembles without tools, which is the difference between a stand set up once and one adjusted often
  • No load rating, on a stand sold for instruments up to 88 keys

Best for: A reader who wants the Z-frame stiffness another page here recommends, at the lowest Z-frame price.

Z-frame. Height 21.2 to 32.4 inches. Width 21.8 to 35.2 inches, stated for 61 to 88 keys. No tools to assemble. $42.99.

The reason to start with the ranges is that its own twin does not publish them. AODSK sells this stand with locking wheels as the AS-ZKW at $44.99, and that listing gives no height figure and no width figure at all — only flexible. Two dollars apart, and one of the two tells you whether it fits.

Twenty-one point two inches at the bottom is the figure that matters for a child or a low bench; 32.4 at the top covers standing play. That is 11.2 inches of travel, and it is published rather than described.

No tools sounds like packaging copy and is not. A stand that needs a wrench gets set to one height and stays there; a stand that adjusts by hand gets adjusted, which is the whole point of buying an adjustable one. No other stand on this shelf states tool-free assembly.

The Z-frame itself is the structural argument, and another page on this shelf has already made it: a single-braced X flexes under a heavy instrument until the movement is something you feel while playing, and Z-frames exist for that reason. This is the cheapest way onto that side of the line.

What is missing is the load figure. AODSK publishes none, and the rule on this shelf is the one that page states: where the maker gives no number, this site does not supply one. Five of the twelve stands here publish one — 100 lb on a wooden stand and 250 lb on four steel ones. Nothing is published about straps, padded arms or non-slip caps either, all of which appear on other stands here.

The product record gives 4,536 g (160 oz), which is 10 lb exactly — the shipping bucket, not a weighed stand.

The questions players ask

Why choose this over the wheeled version two dollars dearer?

Only for the figures. The wheeled AS-ZKW is the same stand with locking castors at $44.99 — and its listing publishes neither the height range nor the width range this one gives. Two dollars is not a real saving; what you are choosing between is wheels and written dimensions. If the stand will live in one place and the instrument has to be measured against it first, the published 21.2 to 32.4 in and 21.8 to 35.2 in are worth more than castors. If the stand gets moved between rooms, pay the two dollars.

Will it hold a weighted 88-key piano?

AODSK publishes no load rating, and another page on this shelf states what follows from that: where a maker gives no figure, this site does not invent one. What can be said is that the listing states compatibility with 61 to 88 keys by width, that a Z-frame is structurally stiffer than the single-braced X-frame on this shelf, and that five of the twelve stands here do publish a figure — 100 lb on one and 250 lb on four. If the piano is a heavy hammer-action instrument, the stands that publish a number are the ones that answer the question.

    AODSK AS-ZKW

    The same Z-frame as the maker’s AS-ZK with locking wheels added, at two dollars more. It is the cheapest wheeled stand on this shelf — and the listing publishes neither of the two adjustment ranges its own twin gives.

    Frame

    • The cheapest wheeled stand on this shelf, at two dollars over the same frame without castors
    • Locking castors: it rolls out of a room and then stops rolling, which a stand on feet cannot do
    • Publishes neither a height range nor a width range, where its own cheaper twin publishes both

    Best for: A keyboard that has to leave the room it is played in, more than once a week.

    • The tier is rated 60 lb, so a second weighted 88-key piano does not belong on it

    Best for: Two keyboards, or a keyboard and a laptop, on one footprint that rolls.

  • AudioSilk room kit of four large acoustic panels in natural finish

    AudioSilk Room Kit, Natural

    Four large panels rather than a grid of tiles — 46 by 23 inches each — in post-consumer recycled polyester, mounted on removable strips that leave no mark, and the only listing here to compare itself with foam.

    Quantity and size
    4 panels at 46 × 23 in — 1.17 × 0.58 m (4 × 1.9 ft) each, the only large-format panel on this shelf. Every other panel here is a 12 × 12 in tile
    Material
    Post-consumer recycled polyester, not foam. AudioSilk states no harsh chemical smell, no shrinkage and no peeling
    Versus foam
    The second bullet is titled BETTER THAN FOAM and claims much higher performance than equivalent acoustic foam — the only listing on this shelf to compare itself with its neighbors’ material
    Mounting
    Removable sticky strips, stated to leave no mark on a wall — and sold separately. The maker says so in the same bullet
    Absorption
    The first bullet reads *High density material with NRC of up to* — and the sentence ends there. No figure is published, and no panel on this shelf publishes one
    Thickness
    AudioSilk puts nothing in writing on this. Two panels on this shelf publish 0.4 in and 1 in, and one publishes 5 cm (2 in)
    Support
    Free acoustic treatment advice is offered, including how to measure room performance and where to place panels — the only placement guidance on this shelf
    Color
    Natural. AudioSilk states a range of colors is available, and two other finishes of this same kit were discarded from this catalog as color variants
    Coverage
    About 29 square feet in total across the four panels
    Fire
    AudioSilk puts nothing in writing on this. One panel on this shelf publishes a fire claim
    Manufacturer reference
    None published

    EAN
    5065015057055
    • Four large panels instead of a grid of tiles, so one wall is treated in four decisions rather than eighteen
    • Recycled polyester rather than foam, with no shrinkage, no peeling and no chemical smell stated
    • The mounting strips are sold separately, which the listing states and which means the kit does not mount as delivered

    Best for: A rented room where the panels have to come down without taking the paint, and one wall has to be dealt with in four pieces.
