Prior to this topper, I had a different brand on my firm fullsized mattress for many years. I like this one so much better because it easier to put on/take off and it fits my sheets better. It also adjust the temperature to the air in the room, and body heat, so I have never felt too hot or cold on it, until I pile on the blankets.Soft, thick, bamboo cover with plenty of room for deep pocket. Well constructed. I purchase the thinner pad, but they have a very thick pad, but this thin one is great for my needs. This is my second purchase.This topper is perfect on my son’s very firm mattress. Not too soft & not too hard. Just right. Super warm & cozy too.this is quite possibly the best mattress topper i’ve ever used, i had a foam topper plus a cover on my bed and it just wasn’t good enough on my hard dorm mattress but this topper is so soft and fluffy and so comfortable, would definitely recommendI got this for my kids bed which was incredibly uncomfortable! But after putting this on there I could possibly sleep in her bed now if I stayed in it that long. The cover took a couple hours to really get it's fluff on. But it's pretty great. I just recently purchased one for my bed.Absolutely outstanding! Made a world of difference on my bed!This turned your bed into an absolute clown. I have placed them on three of my bed now. I have never received one complaint, the complete oppositeTopper is what it's supposed to be; a bit of added cushion for a firm mattress.If you're seeking support, this isn't what you're looking for, however, if you want to add some softness to a firm mattress, this will work perfectly.It's approximately an inch thick, maybe a bit more. I fluffed mine in the dryer first. Cover fit our RV Queen short perfectly. There's elastic all the way around, for assurance it will stay put.It's well made, good stitching and very plush.It's a great solution for us in the rv, and you can't beat the price. Happy campers!! ?♥️i was pleasantly surprised by this. good quality and nice soft fabric. to make it thicker and softer I placed a duvet under it and it made an rv bed much comfier. If your mattress is shot then you likely wont benefit much from this as its not super thick but as a topper, it definitely makes a noticeable difference. All in all, I was pleased with it.Lo compre Para sentir más suave el colchón, cumplió su conetidoBamboo cover with a rayon fill - was expecting a full bamboo experience. While it has helped make our firm mattress better to sleep on it is barely 3cm deep. Would not really call it extra plush. Was expensive for the actually thickness.The topper is as described, well made, comfortable and Quality item.I bought this topper as No One could supply a Mattress Topper without modifying it, as of the different size mattress in Jayco Campers.Thank you
