Excellent new mattresses for our new split king bed. We ordered the adjustable bed frames from Sams to go with these mattresses and am so happy with everything.  They are FIRM,  but that’s what I wanted, I put a 2” gel foam topper on for just that extra cozy feel, but still have the support my 50 year old back needs. I ordered some beautiful split king sheets from Pizuna, my bed is so wonderful, I’m pretty sure this will be my last mattress, the quality seems excellent so far after a month.  My last mattress lasted 19 years so we will see..I did shop around and definitely got the best price here on Wayfair.
