FLYBIRD WB5 Adjustable Bench Review

The bench every other budget bench gets measured against, reviewed on its own terms: what an 800 lb-rated, folding FID bench around the entry price actually gets you, and where it asks you to compromise.

The FLYBIRD WB5 is the value benchmark of the whole adjustable-bench category — it’s the bench nearly every budget competitor is built to undercut, and it’s a top pick in our best adjustable benchroundup. This page is the long version of why it earns that spot. In keeping with how we work at Knurl Knock, we haven’t stress-tested this bench in a lab — we don’t run one. We’ve read the published spec, compared it against the rest of the field, and set out plainly who it fits.

The short version: an 800 lb rating, a full flat-incline-decline range, a long 30-inch backrest and a frame that folds flat for storage, at a price that undercuts almost every “serious” bench, is a genuinely hard combination to argue with for a home gym. It is not a bolted-down commercial bench, and it carries the one quirk every folding bench shares — but for most people pressing at home, it’s the sensible default.

The full review

The rating and the range: the value story

Two numbers do most of the work here. The first is the 800 lb capacity, which combines your bodyweight and the loaded bar — comfortably past what a home lifter benches, so the rating is durability headroom rather than a ceiling you’ll hit. The second is the full FID range: the WB5 goes from a 90-degree upright through flat to a genuine -30-degree decline, which is unusual at this price. Most budget benches skip decline entirely, so getting it here means one bench covers overhead-supported pressing, flat and incline barbell and dumbbell work, and decline movements without a second purchase. Our bench-angles guide explains what each position trains and why the range matters.

The backrest and pad

The WB5 uses a 30-inch extended backrest, which is long enough to support your head and back through a full press for most lifters — a real upgrade over the stubby pads on the very cheapest benches, where taller people hang off the end at the top of an incline. The pad itself is firm. That’s the right call for pressing — a firm pad keeps your shoulder blades set and doesn’t sink under load the way a plush pad does — but it’s less cushioned for long accessory sessions. If you want a plusher, wider pad you’re into more expensive territory. For how the pad, base and adjustability trade off across the category, see our how to choose a weight bench guide.

Folds flat: the feature that sells it

The reason the WB5 became the default budget bench isn’t any single spec — it’s that it folds flat. In an apartment or a shared garage, a bench that collapses and slides into a closet or behind a door between sessions solves a real problem that a heavier fixed bench doesn’t. It means you can have a proper FID bench in a space that couldn’t permanently house one. That portability is the whole pitch, and it’s why the WB5 sits alongside a small-space rack in a lot of first home gyms.

The two honest compromises

No bench at this price is perfect, and two things are worth knowing before you buy. First, like most folding benches, the WB5 has a visible seat-to-back gap— the small opening between the seat pad and the backrest that folding hinges create. It doesn’t affect pressing for most people, but it’s there, and lifters who want a single continuous pad won’t get it from a folding design. Second, the firm pad mentioned above is a genuine trade-off for anyone who does high-volume, long sessions and wants more cushion.

Neither is a dealbreaker — they’re the normal cost of a folding bench at this price, and we’d rather state them than pretend the bench is flawless. If they bother you, the step up is a sturdier, less-foldable bench from a specialist brand (our roundup covers the REP AB-3000 and the heavier FLYBIRD WB7 for exactly that lifter).

Who should buy it — and who shouldn’t

Buy it ifyou want a full FID bench that stores away, you press at home within a normal range, and you value the folding footprint and the low price. For the overwhelming majority of home lifters, that’s the right description, which is why the WB5 is our value pick and the bench the rest of the category chases.

Look elsewhere if you press very heavy and want a planted, bolted-down feel (step up to a commercial-grade bench), or if you specifically want a single continuous pad with no seat gap and a plusher surface (that means a non-folding design at a higher price). Pair whatever bench you choose with a rack that has safeties, so you can bench alone without a spotter.

Common questions

Is the FLYBIRD WB5 a good bench?

For a home gym, yes — it's our value benchmark. An 800 lb rating, a full flat-incline-decline range, a 30-inch backrest and a fold-flat frame at an entry price is a genuinely strong combination. It's not a bolted-down commercial bench, and like most folding benches it has a small seat-to-back gap and a firm pad, but those are fair trade-offs at the price.

Does the FLYBIRD WB5 have a decline setting?

Yes. The WB5 is a full FID bench that adjusts from 90 degrees upright through flat to a -30-degree decline. That's unusual at its price — many budget benches skip decline — and it means one bench covers incline, flat and decline movements without a second purchase.

Can you bench press heavy on a FLYBIRD WB5?

Within reason, yes — its 800 lb rating covers your bodyweight plus a loaded bar for the vast majority of home lifters. What it doesn't give is the planted, bolted-down feel of a heavy commercial bench. If you press very heavy and want maximum stability, step up to a commercial-grade or heavier-duty bench; for normal home benching, the WB5 is solid.

Does the FLYBIRD WB5 fold for storage?

Yes, and it's the main reason the bench is so popular. It folds flat so it slides into a closet or behind a door between sessions — which lets you keep a full FID bench in an apartment or shared garage that couldn't permanently house one.
