Putting These Together Isn't Hard, But It Has a Few Gotchas
I've assembled enough adjustable bar stools over the years that I can do them in my sleep, but Leopard's design does have a couple of steps that people consistently mess up. The instructions that come in the box are decent, but they skip over a few details that aren't obvious until you're already struggling with a stubborn bolt. Below is a walkthrough that covers what the manual doesn't bother explaining. Start by laying everything out on a flat surface and verifying the hardware against the parts list. Leopard usually ships with four main pieces per stool: the seat base, the gas lift cylinder, the footrest ring, and the five-star wheeled base. You should also find a hex key, a couple of washers, and the screws for attaching the footrest. If anything is missing or damaged, don't force it. I once got a batch where two of the four footrest screws were slightly stripped, and trying to torque them down just made things worse. I swapped them out with M6 x 20mm machine screws from my parts bin and the stool held fine. The actual assembly sequence matters more than most people realize. Here's how it goes.
Insert the gas lift cylinder into the five-star base first. Make sure the narrower end goes in and the wider end with the retaining clip faces upward. This part is straightforward, but don't slam it home. You want it seated snugly, not forced. The cylinder should slide into place with moderate resistance. If it won't go in at all, check that the protective plastic sleeve is still on the narrow end. Some people forget to remove that before assembly. Next, position the seat base over the cylinder. The round plate on the bottom of the seat has a hole that aligns with the cylinder's top. Press down firmly until the cylinder fully seats into the base. At this point, the retaining clip should engage and lock the cylinder in place. You should hear a small click. If you don't hear it, wiggle the seat slightly and press again. This is the step where most issues happen because people assume it's seated when it's actually hovering just above the clip engagement point. Now attach the footrest ring. This is the part people rush through. Position the ring around the cylinder at the height you want, then use the provided screws and washers to secure it to the cylinder itself. Do not overtighten these screws. The footrest is typically attached with two or four screws depending on the model, and they go into threaded inserts on the cylinder. A firm snug fit is all you need. Overtightening will strip the soft metal threads, and Leopard doesn't sell replacement cylinders as standalone parts in most regions. Once those threads are damaged, you're stuck replacing the entire column.
After the footrest is on, flip the stool upright and test the height adjustment. Pump the seat up and down through its full range. On the Leopard models I've worked with, the range is usually between 24 and 34 inches depending on the specific variant. It should move smoothly without any grinding or binding. If it feels rough, the cylinder may not be fully seated in the base, or the footrest screws are pressing against the cylinder shaft and creating friction. Loosen the footrest screws slightly and readjust. One thing the instructions don't mention clearly: check that the wheels on the five-star base are all clicked into place. Some units ship with the casters loose in the packaging, and they can fall out during assembly if you're not paying attention. I've found three missing casters in a box of six before, which means the stool wobbles badly until you notice it. Push each caster straight down into its housing until it seats. They should not wobble or come out by hand pressure once installed.

Common Problems and What Actually Works
The most frequent issue I see is the gas lift cylinder failing to stay locked at the desired height. This usually means the cylinder is a lower quality unit, not that you assembled it wrong. Leopard sources different batches of cylinders, and some are simply weaker. If your stool slowly sinks over a few days, the cylinder is tired. There's no repair for that. You'd need to replace the cylinder, which means ordering a replacement gas lift rated for your stool's weight capacity. These typically run between 15 and 35 dollars depending on length and rating. The standard replacement is a Class 3 or Class 4 gas spring, 350mm to 450mm travel, rated for 100 to 150 kilograms. Another issue is the seat wobbling once someone sits down. This almost always comes from one of two things. Either the cylinder isn't fully engaged in the base plate, or the footrest screws are unevenly tightened and bending the cylinder slightly. The fix is to disassemble and redo both steps carefully. Make sure the retaining clip on the cylinder is actually popping into its groove in the base plate. Use a small pair of pliers if needed to gently bend the clip outward, seat the cylinder, then let it snap back. This is the detail everyone misses because the clip is hidden under the seat plate once assembled. The footrest ring can also loosen over time from vibration and movement. If yours keeps loosening, add a drop of medium-strength threadlocker to the screw threads before reinstalling. Loctite 242 or an equivalent blue threadlocker works fine. Don't use the red stuff meant for permanent locks, or you'll be grinding screws out next time you need to adjust the height. A single drop per screw is sufficient. This is something I learned the hard way after a footrest came off during a home event and nearly cracked a tile floor.
What the Instructions Leave Out
Weight capacity on Leopard adjustable bar stools varies by model, but most sit in the 250 to 300 pound range. The limiting factor is usually the gas lift cylinder, not the seat or base. If someone significantly heavier than that rating uses the stool regularly, the cylinder will degrade faster and the seat may sag. There's no way around it. The metal components themselves are generally fine, but the pneumatic mechanism is a consumable part. The swivel mechanism is another area that doesn't get much attention in the manual. Some Leopard models use a simple friction-based swivel built into the cylinder assembly, while others have a separate bearing plate. If your stool swivel feels gritty or sticks at certain angles, adding a small amount of white lithium grease to the swivel interface can help. A little goes a long way. You don't need to disassemble anything for this on most models. Just apply a dab with a cotton swab around the gap where the seat rotates against the base. Assembly time for a single stool is typically 10 to 15 minutes for someone who's done it before. First time, expect 20 to 30 minutes because you'll be double-checking each step. If you're putting together a set of four, budget about an hour total with a break in the middle. Having a small socket set and an adjustable wrench on hand makes the job faster, though the included hex key handles most of it.
If you're missing hardware or the instructions are unclear, Leopard's customer support can usually send replacement parts, but turnaround varies. I'd recommend photographing your parts and hardware against a plain background before disassembling anything, just in case something goes wrong mid-assembly and you need to reference what you have. It sounds minor but it saves a lot of confusion when you're five minutes into a step and suddenly wonder which screw goes where.
