Hi Matt…..I received the Otis grip strips today and they work extremely well with my otis moonshadow mattress. Your customer service is outstanding and I could not believe just how fast I received my order….like in just two days….I was delighted to say the least. 
Thanks so much Matt for your responsiveness no matter how small the order…..Job well done and I will be sure to come back again for any of my futon needs. 
Thanks again…..Lew,….Brooksville, Fl
