Typical sale that comes around every few months. Confirmed that the Cooling Select does not use fiberglass. I'm in my 2nd year with mine, and the medium is a true medium firmness (too soft for my taste).

I have seen mixed reviews on the "cooling" from these, along with the inevitable dip left where someone sleeps after a while...what has your experience been?

Will costco be releasing the rest of their mattress sale next week for memorial day? There wasn't much in the savings book.

I've tested this and the Novaform hybrid comfortgrande. I ended up choosing the Casper. It's a little more firm and you don't get that sinking feeling. Also way cooler. The Novaform I was so so hot. I'm still thinking about returning the Casper for the oasis chill but so far it's not a bad sleep.

It's cooler to me. The Novaform I was sweating like crazy. Also the Novaform is a little softer. You kinda sink more into the bed

How did you return a 'mattress in a box' after it's been opened and expanded?

Anyone know the dimension of the box for a queen mattress? Would it fit in a SUV?
