We can't believe how incredible our ELGIN mattress from ORTHO is! We were a little skeptical of getting the least expensive company--but there is absolutely no reason to doubt. Ortho brand was the best for us. The salesman explained that Ortho has the thickest springs for the most support.It is made in Southern CA and has a less expensive fabric,which is why it is less.The fabric covering is a more breathable cotton and is under the sheet anyway. WE Love it! We choose the individually coated springs, which prevents motion transfer and the Memory foam pillow top. It is so fantastically comfortable that we are in heaven! I like to say that I'm in a candy bar, sleeping in the marshmallow fluff! I'm recommending it to everyone! I was worried about the memory foam heating up, as I read on other reviews, but if you buy their mattress cover, it prevents this completely. We are extremely pleased!
