I have rarely been so for so buy a good product a great value, not only to the mattress cover can be due to the rubber studs can easily insert and no longer slips, no, he is also very fit!. The saver protects the mattress really good and there are no annoying "chattering" more because yes the mattress no longer rests directly on the bed base and thus, of course, extended the life of the mattress. The shipping was very fast on the stage and the packaging was neat, I can recommend this product will definitely continue!.
