This is a genuine replacement remote for the Richmat Mattress Firm 300 (not the leggett and platt black and white remote replacement or the 7 button Topline version) Adjustable Base. If your old remote had different buttons this may not work. Due to supply concerns, the mfg has replaced the 8 button black remote with this black remote made by the same manufacture but all functionality remains (there will be a few extra massage buttons that will not operate but all else is the same!). We can order remotes for the other models but you must view our other Ebay listings. Please contact us if you have questions before ordering to ensure your remote will work and avoid restocking fees. We include directions for easy syncing and ship the same or next day 1st class w/tracking! Most orders arrive to your home within 4 days unless you choose 2-3 Day USPS Priority Mail or 1-2 Day USPS Air shipping at checkout.
