  • Great Bunk Bed Mattresses

    My 6 and 9 year old girls had been complaining for a few weeks that their 4 year old spring mattress was uncomfortable. It was time to buy new mattresses and I made the right choice. The mattresses came shipped UPS during an ICE STORM!! I opened the boxes, cut open the plastic and let the mattresses do what they do. By that night my girls were sleeping soundly and the next morning they were singing "mommy" praises! We've had them for a month now and they sleep so well at night and wake up rested. This is something a parent can't really put a price on but thank goodness they were affordable too!

  • Exceeded Expectation!!!

    I bought this mattress for my 2 year old daughter. I had been shopping around and was convinced we wouldn't get a mattress for under $700. I saw this mattress here and decided it was perfect. The price is crazy inexpensive for the quality you get. I was nervous about the reviews because of the "bad odor" but our mattress didn't have one. It comes rolled up and that made me nervous. When I first cut the plastic, the initial size was only an inch or 2 thick. But I left the room and returned 30 minutes later and this thing fluffs up nicely. We've had the mattress now for about a month and I have already sold 3 more to friends/family. I would encourage you to buy this mattress for any child's bed and it is comfortable for adults as well. You won't be disappointed!

  • Love these mattresses

    We ordered bunk beds for two of our children and ordered these mattresses (one raspberry, 4 blueberry) after reading a lot of reviews. The kids absolutely LOVE these mattresses. They are really comfortable and fit into bunk beds perfectly.

  • Nice Mattress

    This is a great mattress for my granddaughter's new Captain Trundle bed. She loves the raspberry color!

  • Great for Kids

    This is a great mattress for kids! My three year old loves this bed and now stay asleep the entire night. This mattress also feels comfortable to my 6'5 husband. He thinks it the most comfortable mattress in the whole home. The mattress has good support, but also is lets you comfortable, memory foam. This mattress will need good support underneath. It is soft enough that will sink no solid surfaces, like springs. Good for bunk beds, with it only being 7 inches high.

    Sleep Sync Raspberry 7-inch Twin-size Memory Foam Mattress Great bed that kids love and it is what we expected.

  • great for my 4 year old daughter

    this mattress is pretty firm, and you do have to air it out for a day or two. my daughter loves the color, and she was pretty miffed when i explained we had to put a sheet over it! overall, a good purchase.

  • The perfect memory foam

    Super comfortable. Super all around. I've bought three of the sleep sync mattress now and they are perfect for my guest beds and daybed which we use as a couch, so it gets a lot of use. Not too heavy, the velour cover is soft and feels nice. Hightly recommend this memory foam!

  • Very Comfy

    We got this for our 6 year olds loft bed. It fits perfect and is very comfortable to lay on. There really wasn't a noticeable odor from the foam, either. I was nervous about getting a foam mattress since they say they need to air out.

Thank you for your question pbdarwin. Yes, the cover is removable. Have a great day. overstockcustomercare1 on Sep 6, 2013
No, the pink cover is sewn completely around the mattress. I suggest getting a separate cover if you are worried about spills/accidents that would require washing. That's what we did. My daughter hates me covering up her pink bed, but she's okay once I put her pink sheets over the cover I bought. adjones3 on Oct 3, 2013
