Quick answer: For most weighted 88-key digital pianos, the On-Stage KS7350 Z-style stand (around $157-183, rated to 375 lbs) is the stand to buy — it clears knee and pedal space that an X-stand doesn’t, and its weight rating leaves a wide safety margin over any portable piano on the market. If you own a lighter board or just need something cheap and foldable, the On-Stage KS7190 single-X stand (around $33-35, rated to 90 lbs) is the budget pick. Before buying any stand, check its weight rating against your piano’s actual weight — some budget stands advertise “fits 88-key keyboards” while carrying a load rating well under what an actual 88-key weighted piano weighs.
Our digital piano for beginners guide already flagged that “the flat-pack X-stands wobble.” This guide goes further: wobble isn’t the only risk, and a stand’s key-count claim on the box doesn’t tell you whether it’s rated to hold your piano’s actual weight.

1. On-Stage KS7350 — Best Overall / Heavy Pianos
On-Stage KS7350
- Z-style frame rated to 375 lbs — comfortably clears every portable digital piano sold today, with room to spare for sheet music or a laptop on top.
- Legs sit to the sides and back instead of underneath, clearing knee space and giving a sustain pedal a stable, flat spot to rest on.
- Height adjusts roughly 24-38 inches and width roughly 21-33 inches, so it works for seated or standing playing and most 61- to 88-key boards.
A digital piano is a big, heavy box on its own — try Amazon Prime free for 30 days to get it to your door in two days rather than waiting on freight-style shipping for both the piano and the stand. The KS7350’s 375-lb rating is overkill for any single piano, but that’s the point: a Z-stand’s stability comes from a wide, braced footprint, and the extra headroom means you’re never anywhere close to the frame’s limit even with a heavy 88-key hammer-action board like the ones in our Best Digital Piano roundup sitting on top of it.
2. On-Stage KS7190 — Best Budget
On-Stage KS7190
- Single-X frame rated to 90 lbs — more than 3x the weight of any portable digital piano, so it's genuinely safe for 88-key weighted boards despite the low price.
- Height adjusts roughly 27-38 inches with an 11-31 inch base spread; folds flat for storage or transport.
- Bolted steel construction rather than the lighter-gauge tubing some budget X-stands use.
The KS7190 is the stand to buy if budget matters more than knee room — it’s priced close to the cheapest X-stands on the market but, according to On-Stage’s own published spec sheet, carries a 90-lb rating instead of the 20-30 lb ratings common at that price point. That matters because a single-X frame still puts a crossbar near your knees and gives a sustain pedal nowhere stable to sit, which is the exact “wobble” complaint in our beginners guide. It’s the right trade-off for a dorm room or a second practice space, not for a permanent setup where a Z-stand’s extra stability is worth the higher price.
3. RockJam RJX29 — The Weight-Rating Trap to Avoid
RockJam RJX29
- Marketed as fitting "49 to 88 key" keyboards, but carries a published 20-lb load limit — well under the roughly 25-lb weight of a typical weighted 88-key portable piano.
- Double-braced X-frame with a quick-release height adjustment and locking straps; fine for lightweight, unweighted 61-key keyboards.
- Owner reports describe the straps not fitting every piano chassis correctly, on top of the weight-rating gap.
This is the entry we’re including as a warning, not a recommendation. “Fits 49 to 88 key keyboards” is a width claim — it describes how wide the stand’s clamps and rests can open, not how much weight the frame can safely carry, and the RJX29’s listing itself gives a 20-lb load limit. A weighted 88-key piano like the Yamaha P-45 ships at around 25 lbs by itself according to Yamaha’s own shipping specs (confirmed in our P-45 vs P-145 guide), already above this stand’s 20-lb rating before you add a bench, books, or a pedal unit on top. The stand can physically accept a piano that size and still be under-rated for it — exactly the kind of spec-sheet gap our P-45 vs P-145 guide found elsewhere on the naming side of this niche, just applied to a weight limit instead of a model number.
The pedal-unit trap: your stand and your pedal unit might not match
If you want the furniture-style three-pedal experience — sustain, sostenuto, and soft, all built into a stand instead of a single footswitch — check compatibility before buying, because pedal units are usually stand-specific. Yamaha sells its LP-1 three-pedal unit to attach to the matching L-125 stand; it isn’t designed to bolt onto a generic X- or Z-stand from another brand. Roland does the same thing with its KPD-70 pedal unit, which is built to attach to the matching KSC-70 stand sold for the FP-30 series. Buy the wrong combination — a third-party Z-stand with a brand-name pedal unit, for instance — and there’s typically no mounting point for the pedal unit to attach to at all.
This doesn’t affect the single sustain pedals in our sustain pedal guide — those plug directly into the piano’s pedal jack and work on any stand, X, Z, or furniture-style. The compatibility issue only shows up with the built-in three-pedal units that are meant to look and function like an acoustic piano’s pedal lyre.
The bottom line
If you own a weighted 88-key digital piano and plan to keep it in one spot, the On-Stage KS7350 Z-style stand is worth the extra cost — it clears knee and pedal space an X-stand can’t, and its 375-lb rating means you’ll never think about the weight limit again. On a tighter budget, the On-Stage KS7190 is a genuinely safe single-X option at a fraction of the price. Whatever you buy, check the weight rating against your piano’s actual shipping weight before assuming a “fits 88 keys” label means the stand can hold it.
