Hi AT,
I’m not completely familiar with this mattress, but it is from Leesa. The mattress includes 1.5" of 3.75 lb high performance “latex like” polyfoam over 1.5" of 4 lb memory foam over a pocket spring innerspring unit that has 1" of 2 lb. poly foam on top and on the bottom of the innerspring unit. The innerspring unit appears to be (form the photos on the web site) a version of the Quantum Edge from Leggett and Platt. This mattress appears to use high quality materials and there are no lower quality materials or weak links so if it is a good match for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) then it would certainly be a good quality/value choice and would be well worth considering.
KTT enterprises may not carry it in stock but should be able to order it for you if they don’t and some of the others listed in post #4 here may also be able to order it as a special order. Rejuvenite is the tradename for manufactured toppers and pillows from Latex International (now Talalay Global) that contained the Celsion technology. There is more about Talalay Active Fusion (aka Celsion) in post #4 here. The Pure Latex Bliss toppers used the Active Fusion (Celsion) in their covers and their latex, but I’m not sure if they are using it in the foam in their new Pure Talalay Bliss topper line. They don’t currently list it being used on their web site in their toppers, and I know they are not using it in their new covers. The Active Fusion is a paraffin wax phase change material.
