Mine finally arrived yesterday!!! (ordered Jan 1).
Couple quick points...
1. the foundation is VERY stout, with a nice cover. I don't love the plastic style top to it, but it is functional, and it gets covered, so it doesn't matter.
2. Delivery company (here in Sacramento, California area) said they are supposed to assemble the foundation at the shop, but customers have told them they don't like that, and now they are assembling on site, and I'm glad they did. Less chance of losing anything.
3. The Cal King mattress came in full size mattress box AND THREE LAYERS OF PROTECTION. They aren't messin around! Outer cardboard box, inner THICK blue tarp like cover, then inner clear plastic cover. They said they typically fold it in half and carry like a taco. I suggested we just slide it while vertical and still in the blue tarp-like cover. Not easy because it is has no spine compared to a traditional mattress, but on one story house, it worked fine. We took the blue cover off while vertical/leaning, then clear plastic cover off after setting it on the foundation.
4. I am VERY picky about smell, and there is NONE.
5. The top cover is really nice. nicer feel than tempurpedic in my opinion. Not that it matters much, because we immediately covered it with a think/breathable waterproof cover, and sheets.
6. Only issue? under the thick nice cover, I noticed what looked like some creases or folds underneath. I was afraid it was a tear in the latex, so I unzipped the top cover. Underneath the outer cover is an inner-stretchy cover! the anomolies I had seen was just from places the inner cover not being "smoothed", but was easily fixed by a few tugs. Putting the cover back on was a real PAIN.
7. Letter came with it said to wait few hours to let it fully expand. I didn't notice any expansion (or need to), but it was a few hours before we went to sleep.
8. FYI, Delivery company was willing to take my old mattress and box springs for $30, which I was happy to do. Overall delivery was great.
9. Comfort?
Background: I'm 5'10", 175lb, and have been desperate for more support, waking up in pain due to sagging. I also have broad shoulders, and can wake up in pain or with arms asleep with previous beds, so I have tried memory foam and latex toppers (and combinations) on top of older spring mattresses. I tend to sleep on my side, but on a good bet, I can sleep on my back.
Caveat... it's only been ONE NIGHT, and the bed is MUCH MUCH more supportive than any bed in the past, some will call it FIRM, but I think that is because it has great support and not much fluff on top. I am going to sleep on it for a week, then decide if I add a slightly fluffy/gussetted mattress pad on it. I would compare the firmness and support to the tempurpedic classic I tried in the store, but without the "sleeping on sand feeling" of the tempur (not saying that is bad, just drawing comparison about the feeling that when you sync in, it doesn't bounce back like latex).
so it's not luxurious the first night, but I am very hopeful. best of luck to all of you!
