La-Z-Boy Select Mattress – King

The La-Z-Boy Select King Mattress delivers the comfort and support of our Essential King mattress, plus the added benefits of temperature-responsive and antimicrobial properties. Made entirely in the U.S.A., this remarkable bed-in-a-box has a unique hybrid design that features internal pocket coils surrounded by multiple layers of soft, supportive memory foam. The result is a supremely comfortable mattress that conforms to the contours of your body. This breathable design also facilitates airflow, so it’s up to 28% cooler than solid foam mattresses. In short, it’s the only mattress good enough to be called La-Z-Boy.

Feels like you are sleeping on a cloud!
This "mattress in a box" is different than others I have seen! It easily expanded and was ready to sleep on immediately. As soon as you lay on it you feel the mattress forming to your body without the feeling of sinking in. Great mattress!

I love this mattress. It was shipped directly to my home in a box, I took it our of the box, it expanded pretty quickly and was easy to get it onto the bed. I will have to say, I will recommend this bed to others! I am so happy with my purchase!
