Excellent bench machine, the build quality is solid and durable, providing great stability during workouts. Assembly was quick and easy with clear instructions. It’s multifunctional, allowing smooth and effective leg extension and curls exercises, and it can also used as regular workout bench. Very reliable and comfortable machine to add on to my home gym. Highly recommend!

Much higher quality than expected. Thick foam and sturdy build. Feels very stable.

This is a decent piece of equipment for the price! Easy to assemble and seems sturdy enough. Has a slight wobble but once weights are on it it’s not really noticeable. The only issue I would note specifically is the seat depth (front to back) is very short - when seated upright it’s small for even me (5’4 female) and my 6’ boyfriend won’t be able to use it upright which forces a lean-back just to do basic leg extensions!

Bought this for our home gym. It’s sturdy and well built, doesn’t wobble. It took about an hour to set up. We like that it’s adjustable depending on height.

Decent machine for the price The plastic end caps on the pads always pop out onto the floor and you have to keep putting them back in. My machine came with a couple punctures in the black padding and I’ve reached out to customer service but no response back.
