Our Take
The JLL SB400 is a flat/incline/decline (FID) adjustable weight bench aimed at home gym users on a mid-range budget. It accommodates a range of pressing and rowing exercises and competes in the crowded entry-to-mid-level segment. Suitable for beginners through to intermediate lifters who need positional versatility without spending serious money on a commercial-grade unit.
Key Features
Multiple backrest positions covering flat, several incline angles, and at least one decline setting
Separate seat pad adjustment to reduce the likelihood of sliding during incline work
Foam-padded upholstery on both backrest and seat, stitched with faux-leather covering
Folding or compact frame design intended to ease storage between sessions
Steel tubular frame construction with a stated maximum user weight capacity (typically around 150 kg — confirm against current listing before purchase)
Rubber-capped feet to protect flooring and reduce movement during use
Our Verdict
A reasonable starting point for someone building a home gym on a modest budget who wants positional flexibility for dumbbell work and lighter barbell exercises. If you're lifting heavy consistently or expect long-term daily use, it's worth stretching the budget towards a sturdier commercial-grade alternative.
