Pros: soft and squishy, arrived quickly, easy to return
Cons: too soft for my liking
"My old mattress had started to cave in at the center, so I decided to look for a new mattress at a price fit for a student budget. Admittedly, I limited my search to costco.com because the return policy cannot be beat. I ordered this mattress because it had excellent reviews and the price was right. I thought I'd have no problem with a soft mattress, being 110 lbs. How far could I possibly sink in?
The mattress arrived within just a few days. After removing the packaging, there was a chemical odor, but it only lasted a few hours. The mattress had expanded to full size within 3-4 hours. It felt really comfortable. It was really squishy and formed to my body. I didn't have a bed frame or box spring, so I slept with the mattress on the floor. They suggest it lay on a flat surface, so that worked.
The first night was fine. I woke up without any pain. But the second night and every night thereafter was bad. I woke up with this terrible pain in my backbone. I sleep on my back. What was happening was that my hips were sinking in lower than the rest of my body, and it was making my spine bend too far the entire night. I think that even though I am petite and light weight, the way my body is proportioned with more weight in my hips, it just wasn't right for the softness of the mattress. The mattress was too soft to balance out my weight so that my spine would lay correctly. My boyfriend (140 lbs) slept on the mattress one night and loved it. He did complain that it was hotter than most mattresses, but I never noticed.
I desperately wanted to like this mattress. I kept it for 2 weeks. I tried different things, like sleeping on top of the comforter to lessen the sinking in, sleeping with a pillow below my hips, sleeping with a chair cushion under my hips. Nothing worked. So it had to go back. I returned the mattress to my local Costco with no problems. I'm looking at purchasing the Novaform 14" Gel Memory Foam mattress in hopes that it is firmer.
My suggestion is, if you like soft mattresses, give this one a try. If it doesn't work, you can return it."
Cons: off gasses (air it out for a week during the day)
"After 2 months of sleeping on this I can say:
1) I ascertained correctly that this is the "very plush/soft" memory foam mattress model that Costco sells. I know that Costco doesn't do a very good job of saying where each of the mattresses that they sell fall on the firm vs soft scale. I wish they would list it. (I had to parse it together by doing a broad internet search of reviews of mattress names.)
2) Gassed Off a lot. There was a pleasant initial odor that disappeared after the first night (I did sleep on it right away) but even after that odor dissipated I experienced about 2 weeks of waking up with nasal congestion and dry mouth which I presume was the off gassing. I ended up ripping the covers off and letting it gas for about a week with the windows open and that seemed to do the trick and now it's fine.
3) It takes about 4-6 weeks to get used to sleeping on a memory foam mattress. I had come from an innerspring mattress and while I slept like a baby on the first night I found that I would wake up in the morning with a crink in my back or neck (due to my body "sinking" into the mattress) that went away post morning shower. After about 4 weeks my body got used to how soft this mattress is and now I sleep like a baby all the time and love it. (In fact innerspring mattresses now feel too firm to me.)
4) This mattress is great for side sleepers. Yes, it's 8 inches but it's plenty deep for side sleepers. I'm 5'9, 160 lbs and tend to fall asleep on my side and then toss and eventually wake up on my back in the morning and this mattress is great for both. I haven't tested it sleeping belly down."
"The only reason I didn't give this purchase 5 stars is because we've only had it a month. Curious to see how many years it lasts. We've slept great on this mattress since the first day we had it! No more back aches in the morning. One thing that is not mentioned when you make your purchase is to MAKE SURE YOU PUT your memory foam mattress ON PLYWOOD OR OTHER FLAT SURFACE. We put plywood over our original base,(box spring) and put the memory foam mattress on top of that. It's perfect. It's much shorter than our old bed but definitely not lacking in comfort. The odor from the new foam was not overpowering and we were able to sleep on it the first night we had it. The smell disappeared within a day. I love how this mattress cradles your body. I can now sleep on my side or stomach which I couldn't do with our old mattress because over time it had formed a slight dip in the middle. I don't for see that happening to this type of mattress since it doesn't have any springs. Time will tell, but I think overall this was a great purchase!"
Model Number: Sleep Sieince Queen size 8' mattress
"I ordered one for my self and was sooo happy I then ordered one for my mother. She has a bad back problem and has had three back operations and a lot of added hardware installed. Up to this point she has only been able to catch short naps in a reclining chair and not able to use a bed in years. I ordered the bed 1 week before Christmas and she received it in just 4 business days from my order. FANTASTIC service and even received a call from the president of Sleep Science[so much for the surprise. NO PROBLEM] She slept on it Christmas eve and had her first all night sleep on a mattress in several years. The product was even better than the service. I am TOTALLY pleased with the product and just as pleased with the service and the follow up. WAY TO GO COSTCO AND SLEEP SCIENCE You made this Christmas the best in years for our family AND Dreams to come. THANK YOU!!"
Pros: super comfortable and affordable!, doesn't make you hot; breathes well, one of the best decisions i have made for awhile!
Cons: none buy it!
Model Number: Sleep Science Dream 8" Queen Memory Foam Mattress
"For more years than I care to remember, I have had morning backaches, especially upon waking, so I finally decided to try this mattress. So many people said they liked it and, hey, it was Costco - what could be the risk? I could return it if it wasn't any good. Well, I am so glad I did! The very first morning, I woke up without a backache, no kidding! The bed did not smell funny, after airing, as some people have said, and it was ready to go in about 2 hours (filling back up with air). I was even able to manage the box, opening the bed, and setting it up by myself and I am a 57 year old woman (I walked the box down the hall). It is much lower than my previous mattress (12 inches vs 8 inches) so it looked a little funny for awhile, but the sheets stay on (because it is heavy once the air fills) and it is soooo comfortable!"
"I bought this bed when it was $50 off last month or so. I am 5'7 130lbs and before it arrived I thought 8 inches would be too thin for a memory foam, and could imagine myself sinking to the bottom. I am a side sleeper and this is perfect. Not too firm, not too soft. I don't get hot in the middle of the night. Sure I would have liked a 10-inch just to make it look higher, but I could not justify the price difference. I didn't know a lot about the company but I know if anything unnatural starts happening with this mattress, Costco will stand behind this product. Will try to give an update in a couple months to let you all know how it's holding up. So far so good!"
"Within 24 hours of ordering my Sleep Science 8" Mattress, I received a call from the president of the company, thanking me for my purchase. Amazing customer service! When I received my mattress a few days later, I rushed to set it up. I have scoliosis and have heard raves for the help it gives for those who have chronic pain like me. After seeing the high prices for Tempur-Pedic mattresses and reading rave reviews for Sleep Science, I decided to give it a try and I can honestly say, after sleeping on it for almost a week now, I have no back pain! This is amazing!! I highly recommend this mattress! A superb product at a fraction of the cost!"
"We went ahead and ordered this mattress, since our traditional mattress had developed a big crater in the middle. After reading some of the comments, I was prepared for a period of adjustment and the foul odor many talked about. Taking it out of the box there was no odor that I could smell. Even after putting it on the bed, no bad odors were present. The first night we slept on it was just like if we were sleeping on a mattress that we had used for years, meaning there was no period of adjustment. This made me sleep the entire night without tossing or turning. We both are glad we made this purchase."
Pros: great warranty and/or return policy, affordable, high quality, fast shipping
Cons: only available online
Model Number: 582193
"After reading LOTS of reviews online, we finally ordered the Sleep Science Dream 8" Queen Memory Foam Mattress online on 08/16/2013. It arrived on 8/20/2013 via FedEx Home Delivery (from Pomona, CA) in a 67 lb box. It is really wrapped well inside the box - make sure you have a large area in which to open it. The only odor I noticed was when I initially first opened it and it began fluffing up. We let it settle on the floor for 72 hours. Slept on it for the first time last night and it was quite possibly the best sleep I've had in ages."
"After reading all the positive reviews we ordered this mattress. It was very easy to set up and took little time to "inflate". There was no center hump that some of the other memory foam mattresses have. Unfortunately, the mattress is much too soft - you sink right down into it and it cradles you making it much too hot. I woke up with a killer backache, although my husband didn't seem to mind it too much. We both determined we need something more firm."
"I bought this Mattress in October for my King-Sized bed and I honestly can say I've never slept better. Trust me, I did a ton of research on mattresses. My friend paid $5,000 for the same type of mattress but with a more marketed name...it's the same darn mattress!!! So when it came time to buy another one for my guest bedroom, I had no qualms going for this product through Costco. The product is amazing and the customer service from Costco is amazing"
Pros: comfort coolness, ease of delivery and setup
"This mattress arrived very quickly by Fedex. Once the box was opened and the compressed mattress was removed from the plastic it took about 15 minutes to expand to normal size. Pretty amazing.
I get very hot at night while sleeping, sometimes waking up in a sweat. I haven't had any temperature problems since using this mattress. It usually takes some time to adjust to a new mattress but, for me, this one was comfortable right off the bat."
"I'm a retired police officer with a job related back injury. Over the years I have tried all of the popular mattress brands including the tempurpedic and traditional spring mattress. None of the aforementioned have come close to the Sleep Science Dream " Queen in providing me a comfortable nights sleep. The dream provides support and comfort I highly recommend it."
"I was concerned that a foam matress would be too hot for me, but at this price I could take a chance. I am glad I did. It works as it is stated, the center foam core helps to keep the mattress from holding body heat. I am tall and 195lbs. , my wife is shorter and lighter and we both sleep well. We have owned it for several weeks."
Cons: takes a few nights to get used to sleeping on., had stiff back 1st week but fine now.
"Needed a new mattress and read all the great reviews and decided to try it. One of the best purchases I've ever made. Worried that 8" foam would not be enough, but it is fine for me, I'm 5-10, 170 lbs. Would have paid over $1,000 for this quality. Costco is outstanding-ordered on Tuesday, received on Thursday!!!"
"Shipped quickly and not hard to move since it is only 80lbs, not 100lbs like the 14 in memory foam mattresses. Let it air out a couple of days. Took a few nights to get used to it, but after 2 weeks I can say that it was a good choice for a back and side sleeper. Not too firm, not too soft."
Pros: medium firm not as hard as pure comfort, good price
Cons: where is the 20 years warranty.
Model Number: 8-64-Q
"I heard this mattress is too hard somewhere. I have to say it is as good as Tempurpedic. It is made by South Bay International, inc. The only thing is Costco said 20years warranty, and South Bay said only 10 years on mattress, and 2 years on the cover. I wonder where the 20 years come from."
"Very happy with the mattress. We love it. Quick delivery, less than a week, it took about 3 hours to fully "de-compressed". The only drawback is the smell, it took about a week for it to go away, other than that, very please and happy with the product."
"This is a very comfortable mattress...it is a lot lower than my previous mattress in height but oh so comfortable! There was no annoying smell to this mattress either...it truly is a dream mattress...Great price and amazing comfort!"
Pros: excellent price, excellent service and delivery
"The mattress arrived more quickly than expected, within about 4-5 days. Set up was easy and the bed was very comfortable, It is soft, but remains supportive unless sitting on the edge of the bed, when it may depress quite a bit."
