  • Ordered my 2nd mattress.

    I tried the mattress for a trundle bed. It fit perfectly. I know that memory foam takes time to expand and air out. The time was minimal. The smell dissipated overnight. The mattress was so comfortable, that I returned the standard mattress I'd just purchased for my daybed. I ordered a second blueberry mattress. The delivery was quick. I like the soft blue cover.

  • Much too firm

    This purchase has taught me never to buy mattresses online. My kids and I loved receiving it in a roll and watching it expand. That was the best part. This mattress is just too firm. My kids, being light-weights, don't really have any comfort issues (though my daughter stated she would prefer a softer mattress), but the few times I have slept on the mattress myself, I was terribly uncomfortable, and when laying on my side I would get pins and needles. It is however, fairly easy to clean with pee-pee accidents. I used a towel to absorb as much of it as possible and then poured enough hot water mixed with detergent to soak the stain, and then stepped/kneeled on it with a clean towel to soak up the water, and let it air dry for a few hours. No odor, no visible stain.

  • Great Mattress!!

    We tried this exact same matteress at a store and loved it. Found it 1/2 the price here on 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!!

  • 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.

  • I noticed this note in the product description: "■Due to machine cutting manufacturing processes, there may be slight variances in the dimensions of this product."

    • Hello daxi, This should not leave a stain if it gets wet. Thank you for shopping with us.

  • Can this size mattress be used for the bottom of a trundle bed?

    • Hello anneru, This mattress has received excellent reviews! This mattress could definitely work in a trundle bed, but you would want to double check your bed and ensure it requires a twin. I hope this helps. Thanks for shopping with us.

  • Can the cover be removed from the mattress and if so does it zipper/elastic/Velcro back on after laundered?

    • The cover cannot be removed.

  • According to the information shown on, this mattress has a 20 year warranty. I find this too good to be true. Please tell me everything you can about the warranty.

    • Thank you for your inquiry regarding the 20 year warranty for the Spinal Response 7" Twin sized Memory Foam Mattress. That is a limited manufacture warranty that covers defects in workmanship and materials, loose or broken parts not caused by improper care or product abuse. and body impressions of more than 1 inches on all sleeping surfaces. I hope this answer helps you.

  • Do I need or can I use a box spring with this?

    • You can if you want. In fact it makes for a VERY cushy bed. but it is designed for use without a box spring on a platform bed,

    • You don't need one, but you could use one. We're using it on a bed that has 3 inch slats all along the bed, and are not using a bunkie board or a box spring.
