I sucked the life out of a full size mattress topper!

I put a FULL SIZE Novafoam 3" gel mattress topper in one of these..and I used a hand held vacuum to do it. I kid you not! I had to help out a bit by pushing down on the mattress as I sucked out the air but it was so easy. First, I folded the topper into quarters and it was at least 14 inches high. I then stuffed the foam topper into the Spacebag but had a hard time getting the zipper to stay closed. So I used the vacuum to get some air out, I readjusted the mattress and BINGO I was able to get the zipper to stay sealed (running the slider back and forth no less than 5 times). A minute or two later...fourteen inches down to six!

My picture shows the sleeper sofa that the mattress topper is used on and the topper inside the Spacebag. I can now store the mattress under the sofa and not worry about bugs, water, dust bunnies, etc.

I'm completely sold on Spacebag and am now looking around the house for more things to compress!

I don't actually know whether it would make a good mattress topper or not, since I unpacked it and tried to take the label off (who wants to feel glossy paper under their sheet when they're in bed?) it ripped a big hole in the thing.

Love the actual mattress topper and the heat but the skirting that holds it in place and wraps around the mattress is at best crap! Not worth the money!

This thing is useless. It didn't fit my 8" tall mattress, so I thought "I'll just cover the 4" memory  foam topper. Didn't fit...made the corners curl up. Too much hassle to return, so I threw it out. Never again.

Purchased this mattress cover for my 4 year old granddaughters bed. She never peed the bed until she got sick recently. Much to my dismay & disbelief the pee soaked through this "waterproof" mattress cover of course damaging her expensive mattress. Product is past warranty of course. Mattress cover was only $15 but mattress cost $300. I'm livid

WE PUT IT ON OUT BRAND NEW MATTRESS THE MORNING WE WERE PASSING PAPERS ON OUR HOUSE...IT WAS THEN LOADED ONTO OUT RENTAL TRUCK ALONG WITH EVERYTHING ELSE WE WERE BRINGING.....THAT WAS AUGUST 29,2014 MY HUSBAND MADE THE CROSS COUNTRY TRIP AND WAS IN THE SAN DIEGO AREA BY SEPTEMBER SIXTH...I FLEW IN AND HE PICKED ME UP AT THE AIRPORT AND TOOK ME TO OUR SHORT TERM RENTAL. HE CHECKED THE TRUCK DAILY AND EVEN TOOK CARE OF ALL MY PLANTS...THE MOVING MEN WE HIRED CAME HIGHLY RECOMMENDED AND THE FIRST ITEM THAT WAS SET UP WAS OUR BED FRAME, I WAS STANDING OUTSIDE WATCHING THEM UNLOAD OUR VERY EXPENSIVE MATTRESS WHEN THEY (FOUR) MEN LIFTED MY MATTRESS THE "PRO SERIES HEAVY-DUTY SEALABLE QUEEN COVER RIPPED IN ABOUT SIX PLACES AND STARTED FALLING OFF MY MATTRESS AND BLOWING ALL OVER THE STREET  !!!!  NOW MY MATTRESS HAD NO PROTECTION AS IT HAD TO BE BROUGHT INTO OUR RENTAL HOUSE...I PURCHASED THE COVER TO PROTECT MY MATTRESS AND WHEN WE NEEDED THE PROTECTION IT BLEW ONTO THE STREET IN PIECES....IT GOT SCRAPED,AND DIRTY COMING INTO THE RENTAL...AND IT WAS MUCH HARDER FOR THE MOVERS AS THE MATTRESS WAS MOSTLY BRIGHT WHITE WITH SWIRLS OF BLACK...BY THE WAY WE PICKED UP A COVER FOR THE BOX SPRING AS WELL AND PAID SIX DOLLARS FOR IT...WE STILL HAVE IT. I AM ANGRY THAT IT RIPPED TO SHREDS, AND CAUSED IT TO GET SOILED...THE WHOLE POINT OF BUYING THE COVER WAS TO PROTECT THE MATTRESS AND THE COVER IS LONG GONE AND MY BEAUTIFUL MATTRESS IS SOILED...IF I COULD I WOULD GIVE IT A MINUS STAR I WOULD

The topper may be comfortable, but now the horrible smell keeps me awake. I even put the topper outside to air out for two days. That did not do a thing. How are all of you who give such rave reviews managing to cope with the smell?

Ugh I wanted to love, even like this topper but after using it for a few months, I just can't.  I am a side/stomach sleeper and found my back was killing me every morning.  And I found it really hard to get out of bed and not in a good way.  My bed is medium firm and putting this on made it like sinking into a ball pit.  It was physically hard to get out of bed.  My partner agreed so we have taken it off and have no way of returning this huge piece of foam.  I wish I liked it but not so much.

I was skeptical, but willing to try anything that saved me the cost of a new mattress. After years of owning the same mattress (I KNOW - CHANGE EVERY 5-YRS OR SO = PRICE = UGGH!) I started having red, itchy bumps occur on one of my (upper) arms - LIKE, REALLY ITCHY. I hate to admit it, but I thought... "oh, s*&^t, do I have mites or bed bugs, I DON'T EVEN WANT TO KNOW." I did a little research on the creatures and it just disgusted me even more. I didn't want to know. I know, how terrible, maybe I am an anomaly, I have no idea. All I can tell you is, I purchased this mattress encasement, along with the box spring and pillow encasements and NO KIDDING - it has been 1 1/2 mo's and my arm no longer is a problem - itching and reddish bumps are GONE.  I am AMAZED and will probably use these from here on out on every mattress, box spring, and pillows that I EVER BUY. REALLY - one of the best BEST investments!!

This topper felt good to lay on, and it didn't give off gas odors (it smelled like mint!), but it was smaller than my mattress (this might have been intentional?). There was about a 2 inch gap between it an my bed all around, and it drove me nuts. It was constantly shifting around on the bed, I had to adjust it every night, only to wake up to it being wonky again in the morning. I slept on it for a year and then happily ditched it to buy a new mattress.

The memory foam topper just arrived. Unfortunately there was an insect or peice of dirt in the wrapping that made a hole in the mattress!

The top of the mattress topper was too small to actually fit my queen sized mattress, seems like it was designed for a full instead of a queen.

The bottom layer foam seemed to be stained in some parts with a yellow residue.

Not happy with the item and am returning.

I expected to like this mattress pad based on the high reviews.  I ordered the king size.  When it arrived it was vacuum-packed so I couldn't really see or feel it.  I debated on whether or not to open it b/c I knew once I did there was no going back. As soon as I cut the seal the thing started to inflate. This thing has the loft of a comforter - not a mattress pad!  What a mistake this is. I shoved it in my front loading LG washing machine & started it only to get an "unbalance load" error.  I rearranged and tried again to no avail.  Now I have a massive soggy comforter of a mattress pad that I need to lug to a laundromat to wash!  What a hassle!  I already regret this purchase and I haven't even used it!  Wish I knew the king size would need to be washed in a laundromat I would have saved myself the hassle.

I can't feel a difference, my back still hurts like crazy, and even more so, now I sink into a hole that my bf makes when we lay together! And the worst part is, once you let it expand you're stuck with it!!! DO NOT BUY THIS. Save your money and just get a new mattress. Such a joke.

Absolutely the worst mattress ever built. This bag of misery should have a class-action lawsuit attached to it and every owner compensated for the agony it inflicts. After 27 days and 4 complaint calls ("it'll take some getting used to" was their reply), the retailer came out to our house (for only $59.00) and told us it had to be rotated every 2 weeks and it wouldn't leave "valleys" where you actually sleep. In actuality, it needs to be rotated every day BECAUSE IT TAKES A SET THAT MIMICS YOUR BODY AFTER EVERY NIGHT! I'm serious, this was the most ridiculous way to spend $1,899.00 I have ever seen. Sizzling hot in the summer, and when it gets hot, YOU SINK EVEN FURTHER INTO IT'S PAINFUL GRASP! DO NOT BUY THIS MATTRESS-YOU WILL BE SORRY IN LESS THAN 30 DAYS! Good luck trying to contact Sealy, they have the best "communication shield" system I've ever seen-you will NEVER get in touch with a human-EVER! The worst mattress ever built is a gross understatement because it can't even be classified as a mattress-more like a medieval torture device developed by seedy chiropractors to retain clientele! DO NOT BUY! EVER!

this mattress cover/pad was a suggested 'buy with' by amazon when I purchased a 2" latex mattress topper.  I love the topper I got but this mattress pad is horrific.  I put the mattress topper and the pad on at the same time and that very same night I started to wake up damp and uncomfortable.  I figured it was either me or the latex mattress topper was a 'hot' sleep vs. my regular mattress w/o the topper.  I used the mattress cover/pad for about two weeks then decided I needed to do something as I was sticking to my sheets every night...sooooo uncomfortable.

I thought I had wasted $200+ on this purchase of a latex mattress topper.  I decided to take the mattress pad/cover off and put a wool blanket over the latex topper.  Voila!  ; )  No more sweaty damp uncomfortable nights sleep.  I threw the mattress cover in the garbage where it belongs.  Complete waste of money...oh btw it is waterproof.  So if you habitually 'wet the bed' then perhaps it is ok for someone but as I do not wet the bed it is worse than useless.

This by far has been my biggest regret in my history of Amazon purchases. It arrived to my new apartment before I actually moved in, so the leasing staff kindly moved it inside the apartment. Upon my arrival, I thought the apartment smelled odd, possibly due to a fresh coat of paint or new counter tops. I roll out this mattress, and my God, the chemical smell filled the entire apartment. Having read the reviews about the potential smell, I aired it on the balcony for the better part of the day till it looked like it was going to rain. I brought it in, it smelled better, but still had the smell. I went to sleep on it with a mattress cover and a fitted sheet hoping to block the smell. I woke up at 5AM with my lungs burning and the smell covering all my pillows and blankets. There was no escaping it. At 5am, I tossed this mattress back out to the balcony (mind you, I'm 5'6 and this Q size mattress towers over me, but I was frustrated enough to be able to toss it), ripped off the cover to it, and have had it airing out since. I've realized the "fresh coat of paint" smell in my apartment was this mattress's scent seeping through the box. No amount of candles or febreeze has masked the odor. I'll give it one more full honest day of airing out in the Miami breeze, and will trash it if no improvement. I'm now worried about my health as the burning feeling in my lungs hasn't subsided. Obviously this company can't be trusted to give consistent quality of products if some people report the smell and others experience none. Buyer beware
