Firm mattress
This mattress is definitely firm like we needed. It is thick and sturdy. And the material is cooling. I would definitely recommend. I just hope it holds out though the year and more.

Great mattress
Perfect for me. I like a firm mattress. Very well made. It is a bit large extra thick.

King short plank mattress
This was a vast improvement over the original RV mattress. We tried a mattress topper first but that did not work. Manufacturing and delivery was fast. I called to verify shipping date and the customer service was great!
