My experience was very different from the first reviewer. I did not pay for the white glove delivery. I ordered the Sapira at 9:30 p.m. on 2/16/17 and I received the mattress on 2/21017. We set it up last night in about five minutes. It expanded immediately and is perfectly "square" with the foundation.
I've only slept on it for one night so far, and both my wife and I were very pleased with how we slept. It's on the firm side compared to our more than the 10-year-old pillowtop traditional mattress, but it is very supportive and comfortable. I did not toss and turn as much as on a standard mattress. I've not tried a foam mattress, but am very pleased with the Sapira hybrid.
I'll report back if I change my opinion as we sleep on it longer.
Bottom Line: Yes, I would recommend this to a friend
