Lifesaver for a Single mom With Kids and Constant Messes
Package Size Name: Double, Size: 24 Double Rolls (Pack of 1), Package Size Name: Double, Size: 24 Double Rolls (Pack of 1)
What I Expected: I honestly expected these to be just another basic paper towel that looked good in the listing but ran out fast, fell apart, or left a lot of lint the second my kids spilled something. The listing made them seem thick, strong, and a good value for a busy household. What I Got: After using them for a few weeks, I can say they have been a literal lifesaver. Between two kids, muddy shoes, spilled juice in the truck, quick cleanups in the garage, and wiping down the RV before a trip, these have held up way better than I expected. I’ve noticed minimal shrinkage after wet use, and they rarely leave any lint behind, which is a huge plus for cleaning everything from countertops to tools. What I Like: The pick-a-size sheets are great because I do not waste a full sheet for a small mess, and the towels are strong enough that I usually only need one. They are soft enough for everyday kitchen use but still durable when cleaning greasy tools or bigger messes. Quick tip for buyers: keep an extra roll in the truck or RV because they come in handy more than you think. What I Don’t Like: The only downside is that the rolls are large and take up a little more storage space. Final Verdict: Great for families, busy parents, garages, trucks, or RVs. Minimal shrinkage, low lint, and super durable—I will definitely buy these again.

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!
