Great investment to keep your brand new bed safe from accidents. Knock on would haven't had to test it to that extreme, but quality of the product is evident on inspection when received. Very happy knowing my new mattress has that extra layer of protection.
It is hard to keep the sheet on the corners. I purchased straps to hold the sheets in place, so it is no longer a problem. I am very pleased with the mattress and the adjustable frame.
Due to using a CPAC to sleep, having breathing problems, Diabetic problems, excessive sweating at night, Leg cramps, not counting the fighting while napping, I have yet to have a good night sleep on any bed. I get a better nap sitting in an office chair. SORRY, but that's my opinion. I am a Retired Disable Veteran and very hard headed on my opinion.
The mattress pad fits nicely and will stay in place. The pad does not cause the bed to seem warm during the hot days of summer. It was a good purchase.
