Sleep InnovationsMarley 12 Inch Cooling Gel Memory Foam Mattress, Cal King Size, Bed in a Box, Medium Firm Support

I didn't know what to expect buying a mattress online. What if I didn't like it? Could I return it? Or was I stuck with it? The price was good as were the reviews. Enough 5 star reviews to make me say "Yes, let's try it". I'm glad I did.You can hear the whoosh when you first open it. Kind of cool to watch as it expands. It took 2 days for the mattress to fully flatten, but it was vacuum sealed in a box 20 times smaller.I smashed my face into the mattress to "smell" it. Yes, there was some smell. But nothing when walking around the room. The smell was gone with a day or so. Clean, fresh sheets will help hide the smell if you're the sensitive type.Yes, it is a bit warmer than a coil mattress due to the foam density. Is this a bad thing? Not for me. Instead of using a sheet, blanket, and comforter I now just use a sheet. Not having all the covers on my glorious nakedness is quite nice and a welcome change. I can see where the added warmth will benefit people living up north.Is it comfy? Yes, but it took me a few sleeps to get used to it. It's quite different feeling than a coil mattress. No noise and I don't get that 'bouncy' feeling. I would call it medium-firm, which is just right for me. If you have any concerns just head over to Costco, they have the same mattress, just a different brand name.But is a foam mattress Sex Friendly? It is excellent for sex as the mattress is super quiet unlike a coil. But there is no bounce. Some people love a bouncy mattress for sex. If you need a mattress to make yourself bounce you're doing it all wrong. Get those hips moving! You can use the entire mattress...middle, top, sides, or bottom. The foam allows a bit of traction meaning you stay mostly in one spot, instead of launching your partner through the headboards. One major issue...stains. Foam stains badly and generally cannot be cleaned like a coil mattress. A mattress cover will help or wear a full-body condom. Your choice.All-in-all, I'm very happy with my purchase, especially since it was sight unseen. The price cannot be beat, delivery was fast, and set-up was fun to watch.

ORIGINAL REVIEW 2013: I held off on writing this review until my wife and I slept on this bed for one entire year.After toiling for months over which mattress to invest in we decided on this one. First off the mattress was very reasonably priced; the king sized we bought was less expensive than the Sealy innerspring mattress we were replacing (after eleven years) by ~$500. Regardless of the price, this mattress was a great choice. The delivery took several days and came in a vacuum sealed bag. After I brought it up my stairs I placed it on the 7.5” tall box spring (which has 3” support slats) and unwrapped it. I would suggest not breaking the vacuum seal until the mattress is in place because it expands quickly and can be difficult to move once it is expanded. Also be sure that the mattress is facing the right side up. After a few minutes the mattress was at about 90% thickness, after several hours it was fully expanded. We left the window open in our bedroom for the afternoon to let the chemical smell dissipate. When bedtime came the bed was sufficiently aired out and the chemical smell was noticeable only if you really jammed your nose into the mattress. As an aside, my wife and I were prepared to sleep in a spare bedroom if the smell was still too much but we encountered no such problem.Now for the good parts; standard sheet sets fit perfectly on this mattress and laying on the bed was extremely comfortable (analogous to the TempurPedic we tested while buying a different mattress for one of our kids). The memory foam feel is quite different in a good way; supportive but not overly firm. When I was researching memory foam mattresses I got quite confused by the fact that one reviewer would say too firm and the next would say too soft - while referring to the same mattress. After sleeping on the mattress I could rate sleep quality this way: the memory foam becomes very tailored to your body, it feels firm at first but as the foam compresses it supports your body weight in just the right places. The softness feel comes as you sleep on it, it stays soft and comfortable (and at the same time supportive) without feeling like you are sinking into quicksand. It is really great.After sleeping on it for one year and four seasons, I can say that the mattress is still as comfortable as day one. I am a 230lb oaf and my wife is very petite yet we both love the feel of this mattress. There is no warping or hammock-ing of the foam where either of us sleep. Yes, it is a tad warmer in the summer but nothing too drastic.All-in-all this Sleep Innovations mattress is a terrific mattress and an excellent buy. The 12” height is plenty thick and does not make you feel like you have to jump up to get into it like the 14” did. After sleeping on an otherwise high quality spring bed while on vacation, my wife and I both commented on how we could never go back to a non-memory foam mattress again. This was our favorite Amazon purchase EVER and I highly recommend this mattress.Despite my superlatives, keep in mind that what makes a mattress good is a very subjective thing; what is comfortable to me may not be for you - so I attempted to describe this mattress' attributes as best as I could. Hopefully this review helps you decide if it will be a good choice for you. I attached a few pictures for reference.UPDATE 5/1/2015: This bed is still comfortable and it is holding up very well. The foam still compresses and releases as when new and there has been no lumping or hammock-ing. A few months ago I did rotate it 180 degrees to shift the areas that are laid upon as that was recommended to us by other several reviewers (thanks to them!).Still give a full five stars as my wife and I love this bed.UPDATE 11/16/2020: After a bit less than nine years, my side of the bed started to get a little lumpy, presumably from uneven recoiling of the foam after I get up. We loved this bed so much that we ordered an identical one to replace it and the new one seems just as good thus far.

Sleep Innovations Marley contains FIBERGLASS!FIBERGLASS IS NOT A SAFE BEDDING MATERIAL! It irritates your lungs, makes you itch, and will come up through the sheets out of the bed cover. Even if you just sleep on it, your body moving around alone will bring out the fiberglass. Google it.I bought this mattress because I thought it contained no fiberglass, but the tag says the cover top contains 15% contains fiberglass.The full contents of the mattress and information on the tag is never listed in the product description. Buyer beware!

Have no idea if I actually received a Marley as there was no identification on the mattress or box...... but no reason to believe I didn’t as it matches the description. Unpackaged it in the morning and slept comfortably on it that night. It inflated immediately and there was no odour. Would describe it as Medium firm as expected...... good support and comfort for a 6ft 180lb side and back sleeper. My habitual lower back pain has been noticeably relieved and I am sleeping longer and deeper. I had planned on spending more than twice as much on a Costco Novaform but decided on the Marley after reading the Consumer Reports reviews...... and finding the Marley price further reduced by a sale! I am very satisfied with the Marley, especially the value..... can’t be beat!

The mattress is definitely different than a coil. You really sink in when you sit on it. But for sleeping it has been working for me so far. It is on the firm side if that is what you like. I am a 50/50 back to side sleeper . Have had no stiffness in the morning issues. hope it lasts. Some reviews I came across said it has a short lifespan. Time will tell. Its always a risk when you buy a mattress before you try.

I bought this mattress for my mother who is in her late 60's, has MS & is paralyzed from the waist down. She's had her old mattress for 15 years. I thought maybe the switch to the Marley might be uncomfortable for her for a week or two but she instantly loved it!

It didn’t take very long for the mattress to regain its shape after being unpacked.There wasn’t any strong smell that some foam mattresses have.This is a firm mattress, with great support, which is what I was looking for.This is a great mattress, for the price it’s even better.

Bought a twin on sale for $135 best money I ever spent, this bed is a little hard but it’s also awesome if you have hip or back problems just love it. Came in a box unrolled it let it sit 24 hrs!came to true size 10 inches
