Harold P. Verified Buyer
★★★★★
My last Sterling mattress lasted almost 18 years, so I didn't hesitate to replace it with this one. The wave-control layers make a noticeable difference in comfort.
Diane M. Verified Buyer
★★★★☆
Great quality bladder and customer service was incredibly patient answering all my questions about sizing. Just make sure you order the frame and heater separately if you need them.
Ray T. Verified Buyer
★★★☆☆
The mattress itself is comfortable, but I had a small leak develop after a year and the warranty process took a few calls to sort out, though they did eventually resolve it.
