THE GOOD: 10" comfortably firm mattress, strong edges, isolates or minimizes movement from your mate, feels like you are always waking up from a good massage, not clumpy lumpy THE BAD: "creeky" dual box springs are poorly constructed though given an appearance of a good design THE UGLY: your facial expression due to the lingering plasticky odor or aroma which fills the atmosphere for at least a week. Unsure if processed infused foam contributes to allergy symptoms.OVERALL: the bad and the ugly are not enough reason to pass on this MATTRESS. If over 250 lbs, consider that deep sinking into any foam mattress promotes a quick rise in body temps and discomfort, due to its glove-like fit to the body. If less than 250 lbs, the sturdy Mattress will love you for being so manageable. It tends to caress rather than distress less dense beings. Cooling characteristic may not be cooling, but a constant effort to dissipate your 98.6 degree heat build-up, which is unavoidable after an hour or two. By then, you will be in la-la Land and purring like a kitten. The Mattress alone, lives up to its name, because you will only find that your mate got up during the night by asking them the next day. If Serta improves the not-so-Elite boxsprings, the ISOLATION(mattress) would be a really great thing to look forward to, every night!
