I’ve been looking at this one. I think I’ll buy it when I retire the one I have now.
Or this one which is better (I if I have the extra $13)
See if they still make a Steelcase 45412M. I bought my 1986 seat for $60.00 second-hand from an office supply store fifteen years ago. The sales woman claimed its list price was $600.00. I took it apart to clean dust and carpet strings from the heavy-duty wheels and siliconed-lubed them. My now twenty-year old son commandeered it soon after destroying his $14.00 Ikea chair and treated it like the caged gorilla in the Samsonite suitcase commercial. The only wear shown is the worn through fabric wheel he rests his right boot while playing video games. Its simply strong, comfortable, and outstanding like no other.
