    • OMG!!!!
Size: King Style: 12inch Medium-Cooling
Omg, omg, omg. I have been in possession of this mattress since 11am this morning, and it's 7pm now; FedEx delivered. My husband works 12, 16 hour intense nightshift "days", and I'm a mom of 3 kids, 2 who are special needs and have wild sleep patterns. I gave this mattress an hour to inflate and decided to just go for it. I have never written a review so quickly, ever. Between cancer treatment body pain and narrow sleeping windows of time, pressure points, headaches, menopause (I turned 39 this week), you name it, I am one darn damaged individual before we ever talk about my better half. We've dropped $1400 on mattresses, we've had automatic beds, it's been a whirlwind of beating ourselves up over the last 9 years. To the reviewer who said "buy the damn mattress", you are a saint! In four hours of sleeping in the last 24 hours, I am a completely different person. This is the holy grail of mattresses!!! THE mattress! No breathing issues, pressure points, locked up back muscle columns, no cramped neck, headache, I took no allergy meds, my knees aren't throbbing, nobody snored, my shoulders don't feel like I've been hoisting sand bags, same pillow and everything else. I'm in PA, the mattress came from SC in 2 days, and holy cow, I must have been a teenager the last time I felt this good. I know I'm typing a novel, but seriously I'm so cheery, joyful, bouncing around, the kids think I've lost it. I blamed the coffee. The mattress is incredible, beautiful, easy to manage, just perfect. The value, at a quarter of what we've spent previously on other mattresses, just to have me sleeping on the sofa regularly, geez, and tucking support pillows, buying crazy expensive pillows, and toppers, sooo many toppers... I feel like a different person, I'm moving like a different person. All the creams and supplements and OTC pain meds, geez louise it was the mattress! Okay, so I bought the 12 inch king size, medium, cooling mattress, in case there's no header to tell ya. There's support, there's squoosh. We've been using 14 inch height mattresses, so super wild the difference between 12 and 14, I felt like I was stepping into it, lol, but I researched the 2 sizes. We thought that mattered, nope! I feel asleep immediately and had no nightmares. I'm really wondering what the last one was pinching bc it can take me a full half hour to fall asleep and then one slammed car door outside our window an hour later and I'm awake again. The usual tossing and turning and the exhaustion of feeling more tired than when I went to bed, and then my joints are cracking and I'm one cranky mama! Absolutely, 100% buy the mattress!!! I'm going to find out very quickly over the weekend whether I may be able to just empty my medicine cabinet. That pays for the mattress itself! Don't even know what I've spent to fix my raccoon eyes, makeups, serums, strips. All the reviews, the searching, the comparing, being scared, terrified of failure again! I've never, ever "wanted" to go to bed like this. Been excited to go to bed. This is really something. I know you all probably are thinking I need decalf and an antipsychotic, but seriously. You found it; Waldo, the needle in a haystack, this is the ONE! You're awesome, you work your butt off, you need a place to turn off and turn on again. This is it, your hard reset and comfort; the keystone. Go you! You earned it! Life does and will get better! ... show more

    • High mattress with support and comfort
Size: King Style: 14inch Firm
This 14inch king memory foam mattress has completely transformed my sleep experience! The cooling knit fabric cover is soft and breathable, keeping me cool through out the night. The copper-infused memory foam provides excellent support while relieving pressure points. I love how firm it feels, offering the right amount of support for my back. It's also great knowing the mattress is CertiPUR-US certified and made in USA. The fiberglass-free design gives me piece of mind. It arrived in a compact box and setting it up was easy. It expanded quickly and was ready to use in few hours. I have been sleeping better and waking up more refreshed. Overall, it's an affordable, high-quality mattress! ... show more

I am absolutely thrilled with this memory foam mattress! The Cooling Knit Fabric Cover is a game-changer—it truly keeps me cool throughout the night, making sleep so much more comfortable. The 2-layer memory foam perfectly contours to my body, providing excellent support while relieving pressure points. Knowing that it’s CertiPUR-US & Oeko-Tex Standard 100 Certified gives me peace of mind that I'm sleeping on a safe and high-quality product. Setup was effortless, and it expanded to its full size in just a few hours. The 10-year limited warranty is a fantastic bonus, showing the brand’s confidence in its durability. If you're looking for a mattress that combines comfort, support, and cooling features, this is the perfect choice! Highly recommend! ... show more

    • Great Mattress
Size: Queen Style: 14inch Firm
The mattress is exactly as described. It is comfortably firm and supports great whether you are sleeping on the side or on your back. The height also makes it great for my space since my bed is very low. The material also seems strong, and I really like how it is free of fiberglass unlike previous mattresses I have owned. ... show more

    • This is an excellent bed! HOWEVER, it is SO hard! BUT there is a solution.
Size: King Style: 14inch Firm
This EGO of bed is excellent, HOWEVER, the FIRM model is SO hard! Much harder than anticipated. One review said it was hard as a rock and that isn't too far off. There is a little give AFTER you lay there for about 30 seconds or so. But, the initial feel is very brick-like. Be prepared. Here's the good news! Pair with this topper "Dual Layer Memory Foam Mattress Topper for Pain Relief with 2X Support, 2" Fluffy Pillow Top Queen Mattress Topper Plus 2" Odor-Free Cooling Gel Memory Foam Ultra Comfort Mattress Pad Cover" Visit the Biteany Store - you will have the best sleep of your life! You get firm support but also soft comfort from the topper! This is the PERFECT combination. ... show more

    • Meet my expectation
Size: Queen Style: 14inch Firm
The product quality is high and meets my expectations. I no longer experience neck pain after sleeping, and it's not too firm, allowing me to sleep comfortably without a mattress topper. I recommend it!

    • The perfect mattress
Size: King Style: 14inch Firm
This mattress feels amazing, it’s so much better than the Casper mattress I paid 3x the price for. Took a day to expand out the box and air out so don’t expect it to be ready for use the same day but I couldn’t be happier with the quality and value.

    • This mattress is the BOMB!!!!
Size: King Style: 14inch Firm
OMG... I've spent TONS of money in the past on Tempurpedic brand mattresses and this Dyonery King 14" Memory Foam Mattress, out of a box is the BEST!!! I cannot believe how this puffs up and takes shape to be the best mattress I've ever slept on... WOW!! This is unbelievable.... I waited to post this review because I thought the experience might be short lived -- but, it's staying comfortable and not getting any indentations from laying in one spot (which the Tempurpedic has done in the past). I've been sleeping on a Tempurpedic mattress for over 30 years and love the (firm) memory foam. If you prefer the firm memory foam mattress too, don't hesitate to get this one!! It's so awesome!! I love this mattress!!! ... show more
