    • Very firm and comfortable
Size: Queen Style: Firm 1.0
If you like firm mattresses this is a really good pick. Top is also cool and form fitting, I weigh about 250 lbs and I have had no problems with this mattress. Very comfortable. It inflated in approximately 2 1/2 hours. No weird smell either. It’s heavy but it was much lighter than my previous mattress which was coils and foam top. Great quality, good buy. ... show more

    • Hands down ...Best mattress purchase EVER!!!
Size: Queen Style: Firm 1.0
When I tell you that this mattress is EVERYTHING, I mean it's everything!!!. I truly have hip and back problems. I've had them for years. Years of injections, Chiropractic care, and pain meds. In 8 yrs I've purchased a Serta perfect sleep,(medium firm) 1,000 dollars and a Sterns and Foster (medium firm)1,800 dollars and would be in soooooo much pain in the morning. I've never purchased a memory foam mattress before. So in March my son purchased his 3 boys a Nectar medium firm memory foam mattress from Amazon. I sat on one and thought wow, this would be great if it was more firm. I saw Nectar Medium firm mattresses at Sam's but not firm... Since Amazon had Amazon days on October 8-9, I started looking at mattresses since the prices were great. I've looked at sooooooo many then I ran across this mattress and it was 250.00 less than regularly priced. All the reviews, with the exception of one stated that it is FIRM, FIRM, and everyone LOVED it. I figured why not, 350.00 for a firm, copper gel mattress isn't that bad. I took a chance and bought it, and btw an additional 50.00 came off at the checkout. So 300.00. I ordered it on the 8th and it was supposed to be here on the 20th, 2 days later Fed Ex delivered it, Like WHAT!!!!???!!! I was super happy and excited to get it. The box was heavy, my son and grandkids brought it to the bedroom and it was packaged well. I've read it is best to open in a warm room, so I had the blinds open and the sun made my room warm. I opened it on the bed and within 10 mins it was full and exactly 14 inches It is FIRM FIRM....I have never in my life slept so good. Better than a hotel mattress. No indentations, it doesn't move when I get up, my 3 dogs jumped in and out and I didn't wake. I love the grey cover. It's well made, and hey, I'm at the change of life stage and I have NOT been hot at night, no back or hip pains in the morning, no waking in the middle of the night. To be honest, I've been sleeping in as late as two hours past the time I normally get up to let my dogs out. They have been barking to wake me up.. Hahaha... I am super happy, and satisfied with my purchase. I totally, and highly recommend this mattress.. ... show more

    • Excellent value, very firm
Size: Full Style: Firm 2.0
Ordered a king size, after a month still thrilled with the quality and ordered another for my guest room. The difference in the firm 1 vs 2 is just the color. The darker shell looks very premium and the texture adds to the upscale impression. If you are hoping for a firm mattress that is friendly for sleeping and sitting up watching TV or gaming, this is great. No more sore back. ... show more

    • No more back pain!
Size: King Style: Firm 1.0
I have an autoimmune disease of my spine and one of the only mattresses I have been comfortable sleeping in was the Bear mattress. After I got married, my Queen Bear mattress was not large enough for my 6 ft 3 in husband and our dogs. I didn’t want to pay $2000 for a king Bear mattress so I started researching. I came across this mattress, and for the price, I thought “why not”. IT IS AMAZING!!!! It is very firm, so if you don’t want too firm, I would go with the medium firm option. It gives the proper support for my spine and I prefer it over my Bear mattress. When my husband gets out of bed, I don’t feel a thing and my sleep quality has improved significantly. I can’t believe I paid a fraction of the cost of the Bear mattress and received a durable, supportive mattress of such great quality. I bought the 14 inch King Extra Firm. ... show more

    • A great mattress just not for us, read on...
Size: California King Style: Firm 1.0
We bought this mattress in king size exactly 10 months ago. We have slept on it every night except 7 nights. This is our second memory foam mattress in eleven years. My last one was the best but was sold out when we were looking to buy last spring. This mattress is exactly as described so no disappointment there. Yes it is very firm. Yes it is cool. I love the dark cover and it did not have a smell. We allowed it to setup for three full days even though it was ready in about 6-8hours. It is heavy as far as changing linens. Now for the four stars... I have genetic spinal hip deformity...my L5 and SI joint are fused on the left and surgery not an option. I have had upper back surgery and I thought this mattress would be great bc of the reviews however my low back and hips hurt everyday, worse than ever, so that was a huge disappointment. But the bigger disappointment came when hubby said it kills his back since night one with no improvement over the last year and he is very active daily and in great shape. So if you like a firm bed by all means buy away, and if you are peri or menopausal buy away. I bought a three inch memory foam cooling gel topper but still no help in softening it up enough for us. Sadly, we are going back to our original brand we bought in 2014 which calls our names at night! I wish Dyonery had a plush option bc I do love everything else about it! Oh and it is very easy to clean with vinegar and baking soda if needed and it does resist odors and resists moisture and stains to a point. ... show more

    • Very happy
Size: King Style: Firm 1.0
I’m so pleased with this purchase. The mattress is very firm. Exactly what I wanted. The mattress is true to 14 inches at full expansion. It measures at 13 inches at the side but, there is full expansion of 14 inches on the interior of the mattress. As stated, this mattress is very firm. It feels of quality, and I am very happy with this purchase. Very easy to take out of packaging , and set up. Very comfortable for one that enjoys a very firm mattress. ... show more

I didn’t realize how badly I had been sleeping, until I just switched this mattress out with our old one! Had one of those fancy mattresses that was adjustable and all that kinda stuff!! Just time to change, best night of sleep I’ve had in a long time!!!! We had purchased our son another mattress for college last year, it was full on memory foam!! He loves it, but to soft for me! This medium firm is just right!!!! ... show more
