    Sparkle Pick-A-Size
    Package Size Name: Double, Size: 24 Double Rolls (Pack of 1)
    These are not large rolls. I can't say if they are lint free or not. I only use them for spills or to dry my hands. The price is right and they do the job we need. These are satisfactory paper towels for my house. I will buy them again.

    This mattress cover is great! Well worth your money
    Size: Twin XL, Style: 1 Green
    This mattress cover is so comfortable. I am scheduled for back surgery in a week so when I find something I can sleep on and call it comfortable you best believe it is! It fits well, it’s pretty and it’s very fluffy. Seems to be made very well. I am confident that I’ll get a lot of wear out of it.

    Very Comfortable - Love this!
    Size: Full, Style: 1 Green
    So far, so good! I am going on my first night trying this mattress topper out. It feels very comfortable and definitely is fluffy, but not too fluffy. I did not "fluff it out" or put it in the dryer to fluff it out quicker, so perhaps it still needs some time to fluff out some more. It was very easy to place on my mattress. I didn't have to fight with it as I normally would when fitting a sheet to my mattress. I love that it stretches over the sides of the mattress to hold it in place. The bamboo truly gives a cooler effect, which will be very helpful in the summer time. I used a microfiber mattress topper prior to ordering this topper. So far, the comparison is that this one appears to be well made and durable, unlike the microfiber one I had before that changes color as it gets old and dirty and is impossible to clean. The old one actually ripped and would constantly move. I am excited to see how well this one holds up over time. I had no trouble placing a fitted sheet over this mattress topper. I love that this one is machine washable and is able to be placed in the drier. It feels very nice on my legs and is comfortable for my back as well. The padding doesn't feel thick or bulky but definitely adds a softness that is super comfortable. It's too soon to tell if it's water resistant as I haven't tested that feature out yet. I placed it over an old, springy mattress and it truly feels like I have a whole new mattress. Time will tell how well this product does the job and I will update this review if I end up having any issues with it.

    IT'S LIKE SLEEPING ON A CLOUD!!
    Size: King, Style: 3 White
    OMG I AM SLEEPING ON A CLOUD!!! THIS! Life changing!!! We went on a Royal cruise and asked for a mattress topper. When we got home I just had to find one for our bed because I sometimes find it to be too hard. Along comes THIS topper! The very first night it was on the bed I slept the entire night without tossing / turning which I NEVER do! Along with every night since! It fits perfectly on our King bed and no issues with the sheets. It does have a chemical smell when you first open the bag - but I put it in the dryer on air only and the smell dissipated in about 20 minutes. No smell at all by the time we went to bed. it appears to be washable. It's very soft so there isn't really any back support. Just adds comfort to the bed. It is bamboo and really as soft as a cloud! Even my husband got into bed the first night and said AHHHHHHH SOFFT! Super bright white appearance. Not sure if it is water resistant. We added it on top of the mattress protector without any issues. All of the FOAM mattress toppers are terrible! They end up getting really heavy, you can't wash them, they get lumpy, and you end up sweating like crazy on them! THIS - nice and cool! And my hubby runs hot!! I call him the heat miser! No issues! We're both very very pleased!! If you're even thinking about purchasing - ADD IT TO YOUR CART NOW!

    Not like the pictures but well worth the money
    Size: Queen, Style: 1 Green
    4 stars because it is not nearly as padded as the descriptions and images make it seem. The filling flattens easily and doesn’t provide any support. That being said it does make my bed more comfortable and soft and has improved my sleep quality. I have a 12 in soft/medium firm memory foam mattress that was wonderful for the last +2 years till my back surgery ~6 months ago. Since then my joints ached when trying to sleep and when waking, my back would be all out of place and achey, and I was untested. Since buying this topper these issues have improved by 80% or more. It is a great addition to my bed and I don’t regret buying it.
