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.

Get your comfy on
Color: Black, Size: King, Color: Black, Size: King
This Bedsure King Mattress Topper - Viscose Made from Bamboo: This ultra-soft, thick, and fluffy pillow top mattress pad is made from bamboo and is 21 inches deep with a breathable, moisture-wicking design. It’s available in black and measures 78x80 inches. While it’s a great choice, it does take a bit of time to be able to use when you first receive it. First, you need to remove the packaging and then put it in the dryer on low fluff for 20 minutes. After that, you should lay it across your bed for 24 hours to allow it to expand fully. So, plan on not being able to use it for 2 days. However, following these instructions will ensure that you get the best ultra-soft thickness and the perfect fit for your bed, plus you’ll feel comfortable when you’re ready to sleep on it. This Bedsure King Mattress Topper is incredibly comfortable. You’ll have the best nights’ sleep of your life with it. The quality of this topper is exceptional. I washed it, dried it, and it still came out perfect. There were no clumps or bunching. It laid out perfectly on our king bed mattress. This thing feels amazing. I didn’t want to get out of bed. Being a coffee addict, I didn’t mind not having it first thing in the morning because it’s so soft. My husband even approved of this topper. I like how both of lying on it, I don’t feel him moving around. This Bedsure King Mattress Topper is not too soft that you sink in. It’s just right. It’s like a soft hug on your body, but not wrapped around you. After a few days of sleep on it, my back didn’t hurt. I was surprised. I also like how this topper helps protect and keep your mattress from wearing out quickly. It provides long-lasting stability to your mattress. This Bedsure King Mattress Topper is the perfect thickness. I love how my sheets still fit over this and my mattress with no problems. The topper stays put on my mattress also. I like the added elastic band for support keeping it in mattress. We just bought a new mattress and I wanted a topper to add more comfort so this was a perfect addition. Ive bought other Bedsure items for our condo, we rent out and guests always like those toppers. This the first time getting a single topper with no memory foam added separately. I have to say I like the added comfort this Bedsure King Mattress Topper - Viscose Made from Bamboo Ultra Soft Thick Fluffy Pillow Top Mattress Pad with 21 Inch Deep Pocket, Breathable, Moisture Wicking, Black, 78x80 Inch adds to our mattress top. It’s just the right added comfort. You can’t see the wording Bedsure through sheets either. I get do my stretches in bed, yoga and still able to do with no problems. The price is spot on for a nice quality mattress pad. Definitely highly recommend getting this for your mattress. You will be glad you did. It will last a long time.

A better topper from a company I trust
Color: Black, Size: Twin
I have a memory foam daybed that has seen better days. The top layer has started to shift from regular use, and I wanted something that would help hold it together. The Bedsure Twin Mattress Topper does exactly that and made a huge difference right away. This is a high quality, well constructed mattress pad. It fits securely over an extra thick mattress and stays in place. The corner bands under deep pockets are strong and keep everything aligned without slipping. The measurements are accurate. There are instructions to dry it, then leave it out to expand. There was no weird smell. What you see is exactly what you get, in a good way. The cushioning is even and comfortable, and the fabric feels thick and smooth. It adds structure while still improving comfort. It has a more premium look and function than expected, similar to what you would find in a Five-Star hotel. It feels expensive. I also appreciate that the color is not white. It looks cleaner over time and feels like a more practical choice. I have used several Bedsure products, and the quality has been consistent. I also like that it is a woman founded and owned brand, and they continue to improve their products.

adds a touch of comfort!
Color: Black, Size: Queen, Color: Black, Size: Queen
I ordered this mattress topper for our guest bedroom. It is soft and adds a little plushness to the existing mattress. I ordered the queen size for our queen size mattress. It fit well, without much overlap from the mattress topper. The topper has elastic corner bands as well as the fitted sheet like band around the edge, so the topper should stay in place. The color is black, as shown and if you use light colored sheets, it will likely show through. To combat this, I used a white mattress protector overtop of the pillow topper. You cannot see it through our protector and white sheets. The topper is more like a padded mattress protector than a true topper. It reminds me of a pillow top, it's not foam just filled to add softness to the mattress. I think it's a great addition, it adds a little height and comfort to the mattress. Overall, I think this is a nice upgrade to our guest room. It fits well, and serves its intended purpose. I would recommend to anyone wanting to improve the comfort of their mattress.
