I waited a couple weeks to write this review, so I could give myself time to get used to the mattress. First, I'll give the logistics:1. I let it "unfurl" for 2 days, but it really only took a few minutes to reach full height.2. I didn't notice any scent at all.3. It seems much less heavy/bulky than a regular mattress.Now for the comfort/features:I went from a regular spring mattress to this, so it took some getting used to, but now I LOVE my new bed. These are the ways in which I love it:1. Such good support. The medium-firm is quite firm. I was initially a little worried I wouldn't sleep well on it because it wasn't comfy like I was used to my bed being. You don't sink into it, but it's also not uncomfortable. I did sleep well on it right from the first night.2. No bouncing when you sit down on it or when the dogs jump up or down. I don't even wake up when the dogs move around.3. No box spring needed with the right frame. This makes my bed a few inches lower down despite having the same amount of under-bed storage. The lower height will be good for the dogs as they age, because they refuse to use the dog stairs.4. Great price!The only thing I loved slightly less is that the firmness actually made it a little hard on my butt when sitting up in bed reading for a long period of time. The bed was also so flat on top that it looked as though I'd put a comforter on a cardboard box.So to make it a little cushier, I bought a 4" quilted mattress topper. Now I've got the best of both worlds: a firm, supportive mattress in a plush, cozy bed that makes me happy to curl up in it every night.If you're ready to make the switch to memory foam but are unsure if you'll like it, just know that there are options. This one also comes in medium-plush, or you can get the firmer one and add a topper. And at this price, you don't have to be concerned if it doesn't last years and years, because it's cheap to replace.Very happy with my new bed!
