This is a platform that I used under a 40 lb non-suspended turntable and it proved quite effective. Tighter bass and better overall resolution on a suspended wood floor where I have my audio rack. I sold the table and now have a much lighter "suspended" turntable. Comes with 4 spike bases.
The platform measures 23"X 14"X 3.5" and weighs about 35 lbs. The very secure wood crate weighs about another 20 lbs. Local pick up in SF Bay Area is welcome or I may be able to deliver, depending on your location.
