Flybird WB5 Folding Adjustable Bench Review

At a glance

The short answer

The Flybird WB5 is the bench for a home gym that is really a pair of dumbbells and a corner of a bedroom. At $139.99 it folds to 8.6 inches deep, publishes an 800 lb capacity and arrives mostly assembled, per FED Fitness's product page read October 11, 2026.

The pleasant surprise is the documentation. FED publishes a full specification block: footprint, folded size, every back and seat angle, pad lengths and a 2 inch gap between seat and backrest.

The unpleasant one is what is still missing. There is no bench weight and no steel gauge, so the 800 lb figure has no frame specification standing behind it.

The number that should decide your purchase is the 30 inch backrest. The REP AB-3000 2.0 and the Titan Elite Series FID bench both publish 36 inches. Our REP vs Flybird comparison is the long version of that sentence.

What the WB5 actually is, and who sells it

The WB5 is a folding adjustable utility bench sold under the Flybird Series name by FED Fitness, carrying the model code WB5 | FB149 on the product page.

The brand situation confuses buyers and is worth a paragraph. Flybird built its name on Amazon as a standalone brand. FED Fitness now runs Flybird as one series alongside Yosuda cardio, Feierdun machines and Sportsroyals racks. The WB5 is the same bench whichever name appears on the listing.

FED's storefront lists several benches in the series: the WB1 flat bench at $89.99, the WB6 folding classic at $149.99, the WB7 utility bench at $269.99 and the WB10 Olympic bench with leg extension at $239.99, all read October 11, 2026. The WB5 at $139.99 is the entry point, and this review covers that model only.

One reading note matters for anyone checking our figures. The specification block on FED's page is drawn in by the page's own scripts, so a plain page fetch returns the price and the marketing bullets and nothing else. We rendered the page to read the specifications quoted here.

Who the WB5 is best for

The WB5 earns its place for a narrower set of buyers than the 800 lb number implies.

It is a strong fit for:

Apartment lifters. Folded to 30.1 by 13 by 8.6 inches, this bench goes under a bed or behind a door, which no fixed-frame bench does at any price.

Dumbbell-first training. Pressing, rowing, flyes and seated shoulder work with adjustable dumbbells sit comfortably inside the published capacity.

Band training that wants an incline. A bench at 24 or 38 degrees turns a set of resistance loop bands into a far longer exercise list.

Decline work. The minus 30 degree setting is the steepest decline in our bench group, against minus 20 on the BowFlex and minus 12 on the REP.

It is a poor fit for barbell work, because a folding hinge and an unpublished steel gauge are the wrong combination under a loaded bar. It is also a poor fit for tall lifters, and FED publishes the backrest figure so you can check it against your own torso.

What FED publishes, and the two figures it still does not

This section is the heart of the review, because a bench is a specification sheet you lie on. Everything here was read on October 11, 2026.

Published: the 800 lb capacity, the assembled and stowed dimensions, all eight back angles and three seat angles, the 2 inch pad gap, both pad lengths, the bench top height, the pop-pin mechanism, the leveling footpad, a one-year warranty, a 30-day money-back guarantee and a user manual.

Not published: the bench weight and the steel gauge.

Those two omissions are the whole case against the 800 lb number. A capacity figure is only as strong as the frame specification it sits on, and FED gives neither the gauge nor the mass that usually signals thick steel.

Our note on how to read a spec sheet makes the general point. FED has published most of its homework and left out the two lines that would let a buyer check it.

The 30 inch backrest is the figure to measure against yourself

FED calls the backrest elongated, and at 30 inches it is long for a folding bench. It is short for a bench.

REP publishes a 36 inch back pad, 11.8 inches wide. Titan publishes 36 by 11 inches. Both are built so a lifter's head, shoulders and hips stay on foam through a press.

Six inches is not a rounding difference. On a taller lifter a 30 inch pad tends to run out between the shoulder blades and the head, which is precisely where support matters during a press.

The 18.5 inch bench top height is the tallest published in our group, against 18.25 on the Titan and 17.1 on the REP. A taller bench makes planting feet harder for shorter lifters.

Against that, FED publishes a 2 inch gap between seat and backrest. REP publishes 2.1 inches, and neither Titan nor BowFlex publishes the figure at all. On the one specification flat pressers check first, the cheapest bench here prints the smallest number.

How the price is structured

The price was $139.99 on October 11, 2026, with the storefront card reading 96 percent pre-assembled and the page describing roughly a ten-minute setup. Shipping and tax are calculated at checkout; FED's product page promises delivery within five to seven business days rather than a flat shipping figure.

The costs that live in the policies are the ones to plan for. FED's refund policy accepts returns within 30 days of delivery in new or like-new condition with all original packaging.

For change-of-mind returns, FED deducts a 5 percent restocking fee on unopened items and 10 percent on opened items in like-new condition, and the customer pays return shipping at a rate FED confirms during authorization.

On a $139.99 bench that is about $14 in restocking by our arithmetic, plus a carrier fee for a boxed bench, so a return could cost a quarter of the purchase. Keep the box for the first month.

Orders can be cancelled within 24 hours by email for a full refund. By comparison the REP AB-3000 2.0 ships free at $349.99, the Titan ships free at $309.97 with a 20 percent restocking fee, and the BowFlex 5.1S refunds the full product price minus shipping within 30 days of delivery.

Ease of use: why it scores 4.5

Ease is the WB5's best pillar, and it is now built from published figures rather than inference.

It folds to 8.6 inches deep. That single number is the reason this bench exists and the reason it beats every other bench we have graded on storage. The BowFlex stows upright to a 23.9 inch strip of floor; the WB5 goes flat under furniture.

It arrives 96 percent pre-assembled with a roughly ten-minute setup, per FED's own description. The REP and the Titan both ship as kits.

The adjustable leveling footpad matters on garage concrete and old floorboards, and FED publishes it where pricier benches do not.

The mark against ease is the pop-pin mechanism. Pop-pins are slower than the REP's ladder with laser-cut angle markings, and on a folding frame they are usually a two-hand operation. FED publishes no adjustment time and no bench weight, so this review prints neither.

Features: the 3.7 explained

Eight back positions including two decline settings is a competitive count at any price. Many folding benches at this price offer six, and a minus 30 degree decline is a genuine feature rather than a marketing line.

Three seat angles at flat, 12 and 23 degrees is where the sheet gets thin. A tilting seat is what stops you sliding down the pad at steep incline, and three positions against the REP's five is a real difference once the back is at 70 or 90 degrees.

The angle spacing is also uneven. The jump from 24 to 38 degrees skips the 30 degree setting where most incline dumbbell pressing happens, while the REP lists 15, 30 and 45.

There is no leg roller or hold-down in FED's specification block. The sister WB10 adds a leg extension and the BowFlex 5.1S ships a removable leg brace, so decline work on the WB5 relies on whatever foot anchoring the frame provides.

The missing steel gauge is what caps this score. The 800 lb figure sits 200 lbs above the BowFlex's 600 lb combined rating and 200 lbs below the REP's and the Titan's flat 1,000 lbs, and it is the only one of the four with no published frame material behind it.

Value: the strongest argument for the WB5

At $139.99 the WB5 costs 40 percent of the REP and 45 percent of the Titan. For a dumbbell-only gym it delivers the function those buyers need, an adjustable incline that folds flat, for less than a single heavy Yes4All kettlebell.

Value is not the same as quality. The score reflects that the price is low enough that the missing gauge costs the buyer little if the bench turns out to be ordinary, and that a 30-day money-back guarantee exists even if a return is not free.

Value falls for one group: anyone who buys the WB5 as a stepping stone to barbell training. That buyer replaces it within a year, and two benches cost more than one Titan.

If the budget stretches, our adjustable dumbbells vs kettlebells comparison is a better place for the next $200 than a bench upgrade.

Support: why 3.3 is the lowest pillar

Support is scored on warranty terms, parts and how a brand handles failure, and the WB5 sits at the bottom of a group where nobody is generous except REP and BowFlex.

FED states one year on the product page, alongside lifetime technical support and a 30-day money-back guarantee. That is a real published term, and it is the same length Titan gives.

Against that, REP publishes ten years on bench frames and lifetime on structural welds, and BowFlex publishes thirty years on the frame. One year against those is a wide gap.

FED's refund policy is detailed and readable, and it covers defects and transit damage at FED's expense when photo or video evidence or a carrier damage report is provided. The restocking fees are stated plainly too, which counts for something.

Replacement parts are not listed. For a bench with a folding hinge, the hinge is the part most likely to need replacing, and FED does not say whether you can buy one.

What owners report

FED's product page displayed no review count or average for the WB5 in the version we rendered on October 11, 2026, so this review cites no figure from it.

Flybird benches have been sold on Amazon and at Best Buy, Walmart and Target under both names for years, and the public pattern across those listings is consistent. Owners describe the benches as light, quick to fold and adequate for dumbbell work.

The recurring complaints are a seat that shifts under heavier loads, backrest adjustment that takes two hands, and a pad that feels short for taller users. FED's own 30 inch backrest figure now explains the third of those.

We are not quoting individual owners and cannot attribute any complaint to the current revision, because FED publishes no revision history.

Alternatives worth cross-shopping

Choose the REP AB-3000 2.0 if you will ever put a barbell over this bench. It publishes a 1,000 lb rating on an 11-gauge frame, a 36 inch back pad, five seat angles and ten years on the frame at $349.99. Otherwise choose the WB5 if the bench must fold and the loads are dumbbells.

Choose the Titan Elite Series FID bench if you want published 11-gauge steel for the lowest price. It was $309.97 with free shipping in October 2026, with a 1,000 lb flat and 500 lb angled rating. Otherwise choose the WB5 if $170 matters more than the gauge.

Choose the BowFlex 5.1S if you want storage and a long warranty together. It stows upright to 23.9 inches long with a 30-year frame warranty, at a 600 lb combined limit.

Choose the TRX PRO4 suspension trainer instead of any bench if your space is truly tiny, and our small-space home gym guide builds that setup. All four benches are ranked side by side in our best adjustable weight benches guide.

Buy it if, skip it if

Buy it if the bench must fold flat, if your loads are dumbbells and bands, if the budget is tight, and if a 30 inch backrest fits your frame.

Skip it if a barbell is in the plan, if you are tall enough that six inches of back pad changes the press, or if you want a frame warranty measured in years rather than one.

If you buy it, download the user manual from the product page before assembly, keep the box for 30 days and photograph the bench on arrival, because FED's policy covers defects on evidence and charges for everything else.

How this grade was reached, and the bottom line

This grade was built from FED Fitness's rendered WB5 product page and specification block, its storefront listing and its refund policy, all read on October 11, 2026, plus a side-by-side reading of the REP, Titan and BowFlex specification pages. Nobody here folded a WB5, loaded it or weighed it. Where FED publishes a number, this review uses it; where FED does not, this review says so.

One correction belongs in the open. An earlier draft of this review recorded FED as publishing no dimensions, seat angles, pad gap or warranty term, because those figures are drawn in by the page's scripts and are invisible to a plain fetch. FED publishes all of them. The grade has been rebuilt on the real sheet, which moved the score from 7.8 to 7.9.

The bottom line: the Flybird WB5 is a well-documented $139.99 bench for a dumbbell gym that needs to fold away, with the smallest published pad gap in its group and the shortest backrest. Buy it for the fold, the price and the 2 inch gap. Do not buy it for the 800 lbs.

Best for

Apartment and spare-room lifters training with adjustable dumbbells or bands who need a bench that folds to under nine inches deep and costs less than the dumbbells did.
