Mattress protector
Size: Twin
Arrived quickly. No factory odor. Was "scrunchy" out of the package, but fit snuggly around the twin mattress and doesn't make any annoying noise. Basic protective mattress topper. Water proof, but breathable, no condensation under the sheets. Disappointed there wasn't more "fluff", but does the job of protecting my mattress from coffee spills and natural body sweat in between weekly washing. I've had it a while, and it seems to be holding up with monthly washing and drying.

Mattress pad
Size: Queen
This mattress pad is comfortable it makes a difference when it on the mattress. It’s makes the bed feel softer instead of hard.

So far, impressed
Size: California King
Probably not as high a quality as more expensive ones, but fits a California King bed with deep sides perfectly. I am a care-giver for an elderly male and have ordered several because the price is good and I can change them frequently if "accidents" happen. The Mattress Topper Pad does need a large-capacity washer.

Perfect mattress cover, not too thick.
Size: Queen
This mattress cover is exactly what I wanted. I already had a mattress pad, so it was perfect. It’s not thick, it’s just right for what I needed.

Permanent dents
Size: Queen
After months of using this mattress, I wouldn’t recommend it. It’s got permanent indentations where my husband and I routinely sleep. The mattress doesn’t puff back up so. We rotate it but you an only turn it to put the head down where your feet were and back. And there’s no flipping it over. It’s fairly comfortable, but we have a mini foam “wall” between my husband and I.
