I was delighted to see this 4 inch gel infused memory foam mattress topper as I needed more support from my current mattress.  
This mattress topper delivered a most welcomed night sleep.  It comes with a mattress pad thats quilted for additional loftiness and comfort.  The fabric of the mattress pad is soft and can be machine washable.
I have back and hip problems and this mattress topper cradled my back without being too soft...offering support, comfort and coolness during sleep.
Ill have to get new bed sheets as the current fitted bottom sheets do not fit the new 16 height of the mattress  mattress topper. 
Luv, luv, luv it...I would  highly recommend this product.   Be prepared to enjoy the comfort as I spent most of yesterday in bed, and I loved every minute of it.
