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..

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.

I was looking for a firm mattress to support my weight and relieve pressure points. Boy, oh boy, this mattress fits the bill! I don’t mind giving my stats for reference, I am 5 foot five and I weigh approximately 255 pounds. when I lay on the mattress, I barely make a dent, now that’s firm. Although it’s a firm mattress, you feel like you’re laying on a cloud; it is an indescribable comfort. I put it on the bed frame and I was not intending to take a nap, but I laid down and before I knew it, I fell asleep! I woke up refreshed and no pain in my hips. Simply amazing! I’m a hot sleeper and I find that the cool mattress is a godsend. The mattress cover is exceptional quality, slightly textured, and very luxurious. Other memory foam mattresses that I purchased in the past had a terrible chemical odor but not with this mattress. Smells fresh and clean.And it’s Made in the good old USA! Additionally, I purchased the Linenspa XL, twin, electric adjustable base to go with this mattress. It is a great combination to sit up in bed and watch TV or read. Together, these two products make a very stable, XL twin bed suitable for heavy adults. Overall, this mattress is worth every penny and I was able to utilize the $50 off coupon that was offered on the day of my purchase. As an additional bonus, my order arrived a day earlier and promised! I definitely recommend this mattress.

If you need a firm mattress that also contours to your body get this one! Keep in mind it is 14” tall so if you already have a bedframe and a box spring this is gonna be super tall. I’m 5’3 and have to jump a bit to get on while on my tip toes. I’m really hoping this mattress will hold its firmness after 6 months - 1 year. Doesn’t feel cheap like my previous memory foam. We did have to take off our bed sheet in the middle of the night because it kept untucking and sliding around. Because of the height the sheets don’t tuck in so you’ll probably have to buy straps to hold them in place or sleep without a sheet over it. So far I’m loving it

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.
