That looks like a decent solid bench - good price too!
Will get lower once freedom has been established.
I had the same issue then learned you can put the plastic bits in boiling water for a few seconds then they stretch out really easily! I find the bench is sturdy but is too low and not wide enough for a lot of people. I say this and my BMI is 23. It wouldn't be suitable for people particularly overweight
Homcom, make sure you check it for rust.
Caution: mine was extremely poorly milled and packed with metal fillings that all came flooding out over my floor. Probably unlucky, but enough to **** anyone off.
