Review: Love the new topper! - I ordered this topper because our mattress is about 20 yrs old and I didn't like the look of a couple divets when I made the bed. Also wanted a cooling topper. It fluffed up very well after 20 mins in the dryer on low and it fits the bed very well! Sadly the bed has the appearance of lumps when made up but I'm hoping that evens out in time. The topper is very cushy to me but my husband says he can't tell any difference with it on. If you are looking for a topper I can recommend this one. It has no smell of any kind right out of the package. All of the stitching appears nice and tight with no loose threads. It puffs up very well and has improved my sleep with the cooling effect. Love the way it goes so far under the mattress and so far hasn't moved/shifted/bunched up anywhere as you're sleeping. So far I give this topper 5 ⭐️ and will update in the future if needed.
Review: Fluffiness - It’s not really fluffy. It looks good but I needed something fluffier.

## Features

- THICK MATTRESS TOPPER - This mattress topper is overfilled with 8D down alternative fiber filling, fluffy and supportive, providing stress-relieving support for your hips, shoulders, back, and knees. Ideal for side, back, or stomach sleepers. This thick plush mattress cover will save your old firm mattress and refresh you with a luxurious sleep experience.
- BREATHABLE COMFORT - We use an embossed fabric as the surface; it's soft and breathable and treated with Nanotex Coolest Comfort Tech, which accelerates the wicking of moisture. The premium spiral filling allows more airflow in the topper. With good breathability, you won't have issues with overheating, even though it's a thick mattress topper.
- EXQUISITE DESIGN - Baffle box quilting keeps the filling in place and helps distribute body pressure evenly. The raised four sides prevent the filling from leaking out. It seems to wrap you comfortably, and you will feel like sleeping on the clouds. The white hemming makes this gray mattress pad more stylish and modern.
- DEEP POCKET & EASY CARE - The knitted skirt pocket stretches up to 21 inches and can fit mattresses 8-15 inches deep. The 1.6-inch-wide sport elastic trim can securely hold your mattress pad in place, and its excellent elasticity makes the pad easy to fit and remove. No shifting, no noises, ensure a restful and uninterrupted sleep. The mattress pad is machine washable. Tumble under a gentle cycle and air dry naturally to make it fluffy again. Please do not bleach, iron, or dry clean.
- OEKO-TEX CERTIFICATION - SLEEP ZONE, with more than 40 years' experience in the design and manufacture of bedding, has a commitment to quality. Our products are OEKO-TEX Standard 100 certified, so you can buy with confidence.

The SLEEP ZONE Extra Thick Queen Mattress Topper has truly transformed my sleep experience. From the moment I laid down on it, I could feel the plush comfort, making it feel like I was sleeping on a cloud. It offers excellent support, especially for my back pain, alleviating pressure points and allowing for a more restful night. The breathability of this mattress pad is impressive; I didn’t find myself overheating during the night, which can be a common issue with thicker toppers. The elastic-fitted deep pocket ensures that it stays securely in place, which is a significant plus when tossing and turning. Overall, this mattress topper has exceeded my expectations, combining softness with supportive features. As a fan of the brand, I appreciate their commitment to quality, and this product is no exception. If you're looking for a way to enhance the comfort of your mattress, I highly recommend giving this topper a try!
