  1. Affordable Help

    Posted by Unknown

    I recently was able to bring my wife out of a nursing home she had been in for over three years when she had a stroke. My wife is a triapaligic and unable to change positions in bed. When I was getting ready to bring her home I found out that insurance would not pay for anything other than a standard mattress. This has been tried on her before in the nursing home and has always resulted in bed sores. She has been home for 2 months now with no bed sores. The mattress was reasonable priced and shipped quickly. I had it set up on the bed using it as an overlay within minutes and it has been on and running ever since. Clean up is easy when something gets on it, and it is super tough her dog gets up in bed with her at least once a day and there has never been a problem. I would definitely recommend this product and this company for anyone who is lucky enough to be able to have their loved ones home with them.

  2. Thanks Emed

    I was in a bind and needed a LAL mattress right away since my Mom was coming home from the hospital earlier than expected. Emed not only directed me to the right product and save me money, but they got the mattress to me in two days. A day earlier than when my Mom got home. Thanks again Emed. I hope I won't have to shop here again, but if I need something I will definitely shop with you again.

  3. Worth the money.

    I didn't really think that I needed an air mattress, but I'm really glad that I bought one! It came in 3 days and was easy to set up.
