Zinus Support Plus 10” Hybrid of Comfort Foam and Pocket Spring Mattress, King. How much support you need from your mattress is probably just as subjective as how you like your eggs cooked! For those who find comfort in a firm bed with a soft quilted top cover, we developed our Support Plus Extra Firm Hybrid Mattress.
I’ve been sleeping on this for a week now. I let it rise overnight and was able to sleep on it the following night. Mine rose to 11 inches after the first day and I haven’t measured to see if it got to the full 12 inches.It did take a couple of days to get used to the firmness of the mattress, but I do like it. I’m hoping it stands the test of time.
I've never had a firm mattress before and I really like it. I have bad back and knee issues and this seems to help a lot more than the other mattresses I've had
