What are your thoughts on the hybrid vs original casper mattress?

I'm considering this hybrid one

I finally replaced my 2015 Tuft and Needle Kind size and 20+year old box springs. New box springs were Serta available at Costco. The difference is incredible! I love the new mattress even though it has only been out of the box for 2 hours before we slept on it. Very happy with my purchase. I'm a tall 200lb back and side sleeper, wife is a stomach sleeper. We both feel like it's plush and comfortable yet supportive. No more back and shoulder pain from the old sunk in mattress. No more ridge in the middle of the bed from the old broken down box springs.

Let me start by thanking everyone here for so much amazing mattress advice. I read pretty much every post and got some great advice from many, but especially u/the_leviathan711

Background/details: king size bed for 2 side/back sleepers with herniated disks and tons of joint pain. 5'10" 165lbs and 5'3" 156lbs. Do not like the feel of latex, have, in the past, been really happy with an IKEA hybrid that, sadly, broke down too quickly. Tested out lots of mattresses at a local store to figure out what feel we preferred. Loved the Tempur Adapt hybrid but have had a bad experience with the off-gassing, so didn't want one. More concerned about return policy than anything else. Considered DIY and got great suggestions for a build. Worried about the returning/exchanging of individual components, so didn't go that route. Locally, Costco has the best returns, so we looked at what they had available and chose the mattress that most closely resembled a combo of the DIY specs and the Tempur Adapt. The winner was the Casper Hybrid and it has been FABULOUS!

No pain when sleeping on side, wake up without joint stiffness, sleep well. Frankly, it feels like a miracle to not be in pain in the morning and to not toss and turn all night. The edge support is good, very little motion transfer and does not sleep hot (all things I was concerned about). Also, ZERO off-gassing.

Hope this helps someone!
