    I bought this for my daughter's bed and she loves it. The down alternative cover gives it a little more cushion. Good product and arrived in a timely manner also.

    The price was ok, but I'm not sure it was the best item for my bed as it tends to bunch up at the top. Please keep in mind that this adds inches to the depth of your bed which requires sheets with deeper pockets.

    Love this mattress topper. Adds lots of cushion to my hard mattress. Love that you can unzip the pad from the gel and wash. Need to order a third one for another bed.

    This mattress topper exceeded my expectations by far. I went ahead and bought one for my son's bed as well. We all love the comfort and coolness of this mattress topper. If you follow the instructions given to let the mattress lay open for the first 24-48hrs after unpackaging you won't have any problems. We have cleaned the the passes part in the washing machine and let air dry but we tool out the blue part of the pad first then after completely air dried reinstated the blue pad and it was perfect clean and fresh and NO bulging of the padding anywhere. Love this mattress pad made our bed feel like new and we have had it for 8 months or more now.

    So far this gel mattress topper is extremely comfortable. I really like that the cover can be zipped off and washed. I spilled some coffee on mine abut it came out in the cold cycle. I've always wondered how much grime gets embedded in memory foam toppers, but because of the removable cover I have no hygienic concerns. I have not tried flipping it yet but it is not overly heavy so it shouldn't be a problem.

    No smell but it took a couple of days to plump out and it is heavy. Pls remember that it will take up an additional 8 inches of sheet so the bottom sheets no longer fully cover the boxspring. Sigh.

  • So Comfortable.

    Option: Twin

    I put this on top of a 10 inch foam mattress that was very firm. The topper provided just enough "give" to fit my body and provided more comfort during sleep. It is great and I am very happy with the product

Questions & Answers

  • Q:

    "Would this topper be appropriate over my queen size murphy bed mattress in my travel trailer? Would need to fold or roll to store daily."

    • A:

      Hello. I purchased the twin size for my son's college dorm room. When rolled up, it fit into a large Bed Bath and Beyond bag. It sticks out at the top of the bag. A queen size could be pretty big rolled up.

    • A:

      I agree, it is heavy and would take a lot of space. Also check to see if your Queen Murphy bed is stardard size 60w by 78 long, some are shorter

    • A:

      I have an XL Twin and it can be pretty easily rolled up, but it's a bit bulky and heavy. If you need to store it in a small place, it probably wouldn't work for you. It is comfortable, however.

  • Q:

    "I am a side sleeper, will this work for me?"

    • A:

      I am a side sleeper as well who sometimes ends up on my back. I absolutely love this. I've flipped it both ways depending on how I'm feeling. It's helped with my older mattress, as well as my neck and back aches. I didn't want to spend the money on something that would be difficult to send back, but gave in and so glad I did. It is heavy to unroll and you will need to leave it open somewhere for 15-24 hours. other than that, terrific!

  • Q:

    "I'm looking for a topper that I can pack up and fit in a large suitcase or bag. Will this style be easier to pack than the solid foam toppers?"

    • A:

      Hello sarahjane, in my opinion, this item would be an easier alternative traveling with. Please feel free to contact us again with any further questions. Thank you for shopping with us!

  • Q:

    "Why did you choose this product?"

    • A:

      I purchased this topper with cover as a gift. I felt that due to the options it offered (down alternative side, gel side, etc...), it might be a better choice than some of the regular memory foam toppers. The person I purchased this for has a firm mattress and prefers the softness of a pillow-top. Since I can't afford a new mattress, I thought this would be a great alternative. Also, the reviews and the look of the item were factors contributing to the purchase.

    • A:

      I am hopeing it is good , i am do alot of reading what other people say so we will see

    • A:

      It met my grandaughters criteria for her college dorm room.
