Pyle PKST38.5 folding Z-style keyboard stand with padded arms

Pyle PKST38.5

A folding Z-frame whose width slides to any setting rather than clicking into increments, with foam pads on the arms — and the lowest published height figure on this shelf, at 20 inches.

Frame
Reinforced Z-frame with a stated stability lock mechanism, folding to a flat Z for transport (maker’s bullet)
Published range
20 to 34 in. Quoted as the maker gives it — the bullet is headed *infinitely adjustable width* and then says *any height between 20 & 34 inches*. The maker mixes the two words in one sentence; the figures are published, the dimension they belong to is not stated unambiguously
Width adjustment
A sliding lock rather than set increments — stated as infinitely adjustable, where many stands move in steps. The only continuous adjustment published on this shelf (maker’s bullet)
Arms
Foam pads on the arms, stated to hold the keyboard against slipping and to stop the body being scratched. The only foam-padded arms on this shelf (maker’s bullet)
Stated fit
54 to 88 keys (from the title)
Setup
Stated under a minute to set up or break down, packing flat (maker’s bullet)
Load rating
Pyle puts nothing in writing on this. Another page on this shelf states the rule: no published figure, none supplied here

  • Twenty inches is the lowest height published on this shelf — which is a child at a keyboard, not an adult
  • A sliding width lock sets any position, where stepped stands force a choice between two
  • The maker’s own bullet calls 20 to 34 inches a width under a heading about height

Best for: A keyboard shared between a child and an adult, where neither height is a compromise.

Reinforced Z-frame, folding flat. 20 to 34 inches published. A sliding lock rather than increments. Foam pads on the arms. Stated for 54 to 88 keys. Under a minute to set up. $59.99.

Twenty inches is the figure worth buying it for, and the reason is a child. The published heights on this shelf start at 20 on this stand, then 21.2, then 22.5 on four stands, with one wooden stand fixed at 25.2 — and the X-frame already here publishes five settings and no inches at all. Two inches is nothing to an adult and everything to an eight-year-old, where it decides whether the forearms stay level or the shoulders come up. Reaching 34 inches at the other end means the same stand still works when the child is fifteen.

The sliding lock is the second real difference. Four stands on this shelf publish their steps — 1.25 or 1.5 inches in height, 2 inches in width — and a step means the right setting can fall between two wrong ones. A slide stops where you want it. The trade is honest: a friction clamp is a joint to re-tighten, where a pin through a hole is not.

The foam pads on the arms are the only ones published on this shelf. An instrument resting on bare powder-coated steel slides a little and marks a little; foam does neither.

One thing has to be quoted exactly rather than tidied. Pyle’s own bullet is headed INFINITELY ADJUSTABLE WIDTH and then reads a special sliding lock that allows the stand to be adjusted to any height between 2O & 34 inches. The maker uses both words in one sentence. The figures are published; which dimension they describe is not stated unambiguously, and this page is not going to decide it for them.

Two gaps. No load rating — and another page here states the rule: where the maker publishes none, this site does not invent one. And no straps: the keyboard is held by friction and foam, where five stands on this shelf tie it down.

The product record gives 4,400 g (155.2 oz).

The questions players ask

Why does 20 inches matter?

Because it is a child’s playing height, and almost nothing on this shelf goes that low. The published figures here are 20 in on this stand, 21.2 in on one Z-frame and 22.5 in on four others; a wooden stand is fixed at 25.2 in. The X-frame already on this shelf publishes five settings and no inches at all. Two inches sounds like nothing until the player is eight years old, at which point it is the difference between forearms that stay level and shoulders that rise. And the same stand reaching 34 in means it does not stop being useful when the child grows.

What does infinitely adjustable actually mean here?

A sliding lock instead of holes and pins. Most stands move in steps — the four Liquid Stands on this shelf publish theirs as 1.25 or 1.5 in in height and 2 in in width — which means the right setting may fall between two of them. A slide stops anywhere. The cost is that a clamp holds by friction where a pin holds by steel, so a sliding lock is the joint to check and re-tighten. It is the only continuous adjustment published on this shelf. It should also be said that Pyle’s bullet is headed *infinitely adjustable width* and then quotes a height, which is the maker’s wording and not a tidy specification.
