Memory Foam Home Healthcare Mattress

I have had a vibrating, movable position, electric bed in my living room since the middle of the 1980s. I desperately need it because of a combination of spinal problems due to genetics, as well as to a car accident in 1999 that severely injured soft tissues in my back, as well as another disc. I could not afford to buy a new electric bed, although my bed's mattress had been worn out and lumpy for years. I had compensated for this by using numerous pillows, folded old towels underneath the mattress to keep it level, etc. I accidentally discovered this Home Healthcare Mattress, I ordered it, and I replaced my old mattress with it. No more pillows, etc. and I now can read, watch DVDs. etc. in my living room comfortably. This mattress is thick enough not only to be comfortable, but also to cushion and to support the painful areas of one's body, helping greatly to relieve pain!! I was so impressed that I then bought the Premium Home Healthcare Mattress, that is 4 inches thick and that I had not noticed before buying this 3 inches thick mattress, as a backup. I was afraid that I would never find such good mattresses for such excellent prices to fit my electric bed again. I have covered my mattress with a 90 in. x 90 in. comforter. This size is adequate for my bed (I want the one side to go to the floor and the comforter to cover the bed from head to foot) because one of its sides is against a living room wall. Also, I use large safety pins to pin the comforter to the mattress. My old mattress is going to the dump!
