  • Great Mattress!!

    We tried this exact same matteress at a store and loved it. Found it 1/2 the price here on overstock.com. Our daughter loves it and won't go back to a traditional mattress. It arrived quickly. Definately needed to let it fluff up after being vacumm sealed, but was great! We're using it on a bunk bed and is the perfect size. We're thinking of replaceing our guest room queen bed with a blueberry when the time comes! An excellent matteress for an outstanding price!!

  • My child FINALLY sleeps through the night!!

    Bought this mattress for my 2 year old's race-car bed-PERFECT FIT. Item is exactly how it was described. THERE WAS NO ODOR! Opened it the day it came and followed instructions for "airing out". My son had only slept through the night half a dozen times since he was born before we bought this mattress-now he sleeps through the night EVERY night. This mattress has been a LIFE-SAVER!!

    • Would you recommend this to a friend? Yes
  • Ultimately Good-Chemical Smell At First

    I purchased this mattress for my 3 year old since he had outgrown his toddler bed. The size is perfect. As other reviews have noted, there is a very strong chemical smell when the mattress is first unwrapped/unrolled from the plastic. Ideally you should air it out for a few days prior to using but we're in a small apartment had no where to do so. I was concerned about the smell but my son slept fine on it the first day out of the package. My son loves his blueberry bed and the cars and toy story sheets I purchased to put on it.

    • Did the color match the color displayed onsite? Yes
    • Did the description onsite accurately describe the product? Yes
    • Would you recommend this to a friend? Yes
  • A lovely night's sleep. Again, again, and again!

    Sat Aug 18 2012 12:56:28 GMT-0500 (Central Daylight Time) Once you get past the smell... Well, just air it out a while. It's worth the trouble. I hope that, if this one ever becomes unusable, I can get an identical replacement mattress. Yes, it's a twin and, I am an adult male but, I am only 5'3". So, if you're looking for a twin and, you have verified that the size fits your needs and, you are considering this mattress, buy this mattress.

    • How did the color on site compare with the actual product? Fine

  • Great mattress for the price

    I was a bit concerned as it was very thin out of the box. I knew it would expand, but didn't realize that it would expand to be pretty much the thickness of an innerspring mattress. It's very comfortable; perfect for the platform bed in my guest room.

    • How did the color on site compare with the actual product? accurate
    • Please tell us about the quality of the product. I's very comfortable. It's in my guest room, but I slept on it myself to be sure.
    • How accurate was the on site description of the product? very accurate

  • sleep sync blueberry 7 inch twin size memory foam

    I originally ordered this mattress for a twin over full bunk bed that I have at my beach house in ocean city, nj, but I asked my 17 yr old grandson to try it out first in his bunk bed at home because his mattress was old. After sleeping on it for 1 week, we threw out his old mattress, & he will not give the blueberry mattress back. I may have to buy another blueberry mattress.

  • Just Amazing mattress!

    I have already had one mattress like this since 2009, it was purchased in *** for my baby, but since he was a little one, my mom slept on it...and all the family adored this mattress. That is why I was looking for the same or close to that we already had. I definitely love this mattress, it repeats the contours of your body and makes you feel comfortable during the resting time or overnight.
