Tempur 30% off sale

I wonder how many people would buy a tempur model on discount even though there are no returns. The breeze 30% off deal going on right now has me thinking about it. I’m a little nervous because it’s seems a lot of ppl return their mattresses during trial. But I have a split tempur adjustable frame but have a regular cali king right now. I didn’t plan on getting a split cali king (even tho I want it) because of the price. The hybrid was $8k but with sale it’s now $5600. I’ve been to the mf store 3 times to try different t ones and like this. Current bed I’ve had for 5 years and cost $400 from Sam’s club. I don’t have any pains or anything but it’s not the greatest especially for a side sleeper. The lux firm was $10k and now $7k would be another option but that might be a stretch when the hybrid would do. What do you all think?
