I got my last mattress from Costco, it last about 7 years. It was ok and still worked. But recently I decided to replace it for a new one. Mainly because my back started hurting in the morning when I woke up, another reason was my kid peed it when she was potty training. Now she is old enough for not doing it again so I was thinking maybe it was the time for a new one. I chose Amazon for this one basically because it was more affordable and you never worry about the shipping. Now I can confidently say that it was one of the best decisions that I’ve ever made. It’s incredibly comfortable and the support it has significantly improved my sleep quality. What I love most is the balance between softness and firmness. It gently contours to my body without making me feel like I’m sinking. Whether I’m sleeping on my back or side, I wake up feeling rested and without any back pain. No more back pain!! Yay!!
Another plus: the mattress came with a cover!! It stays cool throughout the night which is great for someone like me who tends to get hot easily.
If you have the budget for it, I highly recommend investing in this mattress. It’s a game changer for comfort and over all sleep quality.

I’ve been looking for a 14-inch mattress for a while because my bed frame is quite low, and my previous 12-inch mattress just wasn’t high enough. I actually bought another mattress that claimed to be 14 inches, but even after letting it fully expand for several days, it only reached 12 inches — so I had to return it. Then I found this one, and I’m so glad I did!
After unboxing, I let it sit for two days and it fully expanded to a true 14 inches, just as advertised. The height is now perfect for my bed.
My old mattress was a spring mattress, and over time it started making squeaky noises every time I turned over. This memory foam mattress is completely silent and much more comfortable. I got this for my child, and I feel memory foam is better for growing bodies and proper bone support. It’s medium firm and provides great support without being too hard.
Overall, I’m extremely satisfied with this purchase. It’s exactly what I was looking for — true to size, very comfortable, and no noise. Highly recommend!

Ordered this mattress to replace a standard coil mattress that had me sleeping in pain and waking up uncomfortable. Never thought a mattress in a box would be this comfortable. Box was almost 100 pounds and arrived in good shape mattress rolled tightly inside as soon as you start cutting open plastic it starts to take shape, they even include a cutter for the plastic. Within 30 minutes mattress was fully shaped. Off gas smell not too bad and was hardly noticeable after a night. Sleeping has greatly improved as your body sinks in and is fully supported. Waking up in the morning my hips and back actually feeling relaxed. Cooling not a huge difference but definitely provides a cooler night’s sleep. Very happy with purchase!

I am very pleasantly surprised by how awesome this mattress is. It’s firm with just the right amount of support and just the right amount of softness. I used to turn over on my mattress a lot and I would feel almost immediate pain right away in my shoulders. This mattress makes it the complete opposite to turn over, I actually feel excited to turn over because it’s so comfortable and I have no pain. Way worth the $, I can’t believe more haven’t bought it.

Having the mattress for over a month now, I am pretty satisfied with the quality so far.
First time purchasing a king size mattress on line, the package is smaller than I expected for a 14 inches at first. Then after we cut the plastic wrapping,it expanded into a king size in mins. Like magic. Great height for the 14 inches . Overall the mattress provided a great comfort and coolness at night time. Great firmness for adults. There is nothing I could complain about so far. Great investment and would definitely recommend it.

We took a risk buying an expensive mattress online, but it paid off. The mattress arrived on time, was easy to “assemble” (only had to cut off the plastic cover), and then we let it air for 2 days before using it. There was no off gassing smell as other reviewers noted.
The mattress looks great and is extremely comfortable. I was initially worried about it being too soft (may have laid on it for a couple of minutes as soon as I got it out), but after it sat for 48 hrs it firmed up nicely. It absolutely has helped alleviate our respective back pains, which is why we bought this mattress. Waking up to no more back pain has made this purchase worth it.
I love that it doesn’t transfer motion as I get up frequently during the night for baby duty. There’s been no sinking, and I fully expect this mattress will last a long time. If anything changes, I’ll update the review.

I am so happy that we ordered this mattress. Tried many others so far this is the only one that is firm enough for me. I prefer firm rather than the soft mattress. Later I sleep better at night as supposed to wake up by in the middle of the night as my partner who toss and turn a lot thru out the night. It is hard to find a right mattress to match every one’s preferences. The airflow is good too I feel cool every night so far. This comes with protection plan so I have nothing to worry.

I paid the price for not following the instructions and letting the mattress fully expand for 48-72 hours. I had read comments that mattress APPEARED to have fully expanded within mins. Because I was dead tired, I hopped into bed about 2 hours after opening plastic.
Since I sleep toward edges of mattress, for 3 nights, I slept on one side and sunk deeply into mattress where it was hard to turn over and wasn’t super comfortable, and oh how hot! I thought the mattress was just softer than expected and contemplated going back to my too-firm mattress until I happened to roll to the other edge that had fully expanded! Hall-le-lujah 🎶… Heaven… firmer but not too firm support where I wasn’t sinking into mattress and it wasn’t as hot. Plus, I slept 8 full hours without getting up for potty break 😀. So now I’m like the other reviewers who say they don’t want to get out of bed.
