Our Take
The JLL SB300 is a mid-range FID (flat, incline, decline) adjustable weight bench aimed at home gym users who want versatility without spending serious money. It handles dumbbell pressing, flyes, and supported rowing, and sits comfortably in the budget-to-mid market — above basic flat benches but well below commercial-grade kit.
Key Features
Multiple backrest positions covering flat, several incline angles, and at least one decline setting
Separate seat pad adjustment to reduce the "banana back" sliding problem common on cheaper benches
Steel frame construction with a powder-coated finish for basic corrosion resistance
Foam padding on both backrest and seat, covered in a stitched PU vinyl upholstery
Folding or compact design for easier storage in smaller home gym spaces
Rubber non-slip feet to reduce movement on hard floors during use
Our Verdict
A sensible starting point for a home gym user training with dumbbells up to moderate weights who needs incline and decline options on a tight budget. If you're lifting heavy barbells, training seriously four or more days a week, or expecting commercial durability, you'd be better served by spending more.
