This mattress is an excellent option for those looking for comfort and a good night's sleep. It is made with refreshing gel memory foam that maintains a pleasant temperature throughout the night and adapts well to the body. It is medium firm, perfect for me, neither too soft nor too hard. After a few nights, I noticed an improvement in the quality of my sleep. My back hurts less compared to my old spring mattress. The mattress expanded quickly after unpacking it, and it's definitely worth the price.

I've been using this full-size hybrid mattress for a couple of weeks now, and honestly, it has exceeded my expectations. The combination of memory foam and innersprings offers the ideal balance of softness and firmness. It contours well to the body without sinking in too much. I was surprised by how easy it was to unpack: it comes vacuum-rolled, inflates in a matter of hours, and didn't have a strong odor like other new mattresses. From the first night, I noticed the difference: I no longer wake up with back pain and I barely notice my partner's movements. Plus, it stays cool all night, which I really appreciate since I tend to sleep hot. I definitely recommend it if you're looking for a quality, comfortable, and reasonably priced option. It's worth every penny!

I can't even believe how comfortable this mattress is! I was so worried ordering a mattress online that comes vacuum sealed in a box but so so glad I took the chance. This King size mattress is medium firm and sleeps like a dream!! The quality is superb, nice thick materials. I'm 40 and after having four children I suffer from chronic hip pain especially when sleeping. Haven't had any pain at all at night since sleeping on this mattress for 2 weeks. It was easy to set up, just cut the seal and it inflated to about 95% immediately. We did wait 72 hours just to be sure. During those 72 hours we also pulled up at the corners because some reviews said the corners didn't inflate properly. We did not have this issue, possibly because we took the time to stretch them out. Also there's almost no motion transfer at all. We can both get up without waking each other. It's a true king size as well. The top is just so nice, thick and soft, no need for a mattress pad or thick topper. Id say we are average size people and it supports our weight nicely. Doesn't sag or sink in when sleeping. Our kids have jumped all over it with no issues. Overall an outstanding purchase and I would recommend all day long!

Good sturdy, quality mattress. I let it decompress for 48 hours as instructed. It is as described. My son weighs 228 lbs and he finds it comfortable and supportive. This mattress makes him feel fully rested. Only issue I see that I don’t like is two of the four top corners bend down slightly. Otherwise, I’m pleased with the purchase.

I bought this KOULABR Z queen mattress for my mother, and it’s been one of the best purchases I’ve made for her comfort. She has osteoarthritis and often struggled with joint pain at night, but since sleeping on this mattress, she’s been waking up with less stiffness and discomfort. I’ve noticed she’s sleeping through the night more often, and she even mentioned she feels more rested in the mornings. It was also incredibly easy to set up — just open the box, cut the plastic, and let it open up. Within minutes it was ready to use, and there was no strong chemical smell. The mattress has the perfect balance of softness and support, feeling plush without sinking too much. It’s truly been a game changer for her sleep and overall comfort. Highly recommend for anyone looking for both quality and relief from aches and pains!

⭐️⭐️⭐️⭐️⭐️ A Game-Changer for My Sleep! I was a little hesitant to buy a mattress online without trying it first, but I’m so glad I took the leap. From the moment it arrived (packaged securely and easy to unpack), I could tell it was high quality. The setup was simple and the mattress expanded quickly with no strong odor. Sleeping on it has been a dream—literally. It strikes the perfect balance between support and comfort. I used to wake up with lower back pain, but after just a few nights, that’s completely gone. It contours to my body without sinking too much, and I stay cool throughout the night. Customer service was also top-notch, and delivery was faster than expected. If you’re on the fence, I’d highly recommend giving this mattress a try. It’s one of the best purchases I’ve made all year! ⸻
