From the moment I opened the box, I could tell this mattress was high-quality! It expanded quickly, with no weird "new mattress" smell, and was ready to use right away. The first time I laid down, I was blown away by how comfortable it was—soft but with great support. The combination of springs and foam is perfect, giving me the support I need while feeling completely relaxed. Now, I actually look forward to bedtime every night! Definitely a worthwhile purchase, and I’d recommend it to anyone looking to upgrade their sleep experience!

This bed is ridiculously comfortable. We only got it a little over a week ago. So, I’m still a little sore when I wake up. BUT I know I’m sleeping better because I am sleeping through ALL of my alarms. It doesn’t matter how many I set, how loud, etc. I’ve slept through them every morning. Thankfully, I’m a SAHM and naturally wake up with my daughter. So, the only thing it has cost me thus far is my morning coffee time. There was no smell to the mattress. Although it’s big and heavy, I was able to move it upstairs and set it up on my own. It’s a perfect medium firmness, and I can soundly sleep on my side, back, and stomach with a husband and 2 large dogs. All in all, an incredible bed. Especially for the cost. But fr make sure you have a good alarm 🫠

I recently tried out this mattress, which arrived compressed and neatly packed in a box. The compact delivery was so convenient; I could easily move it to my bedroom without any hassle. Once unboxed, it began to expand immediately, which was fun to watch! I left it to fully inflate for a few hours as suggested, and it was ready to go by bedtime. After a few nights of use, I'm genuinely impressed by the quality. The mattress feels supportive without being overly firm, and the top layer adds just the right amount of softness. I've experienced less tossing and turning, and I feel much more rested in the morning. Overall, I'm happy with this purchase. The mattress was simple to set up and offered great comfort for the price. Definitely worth a try!

I have to say, when I unboxed and saw this rolled-up mattress, I couldn't believe my eyes. It was packaged with such care and quickly took its perfect shape once unrolled. I had my doubts about the comfort and quality of a rolled mattress, but this one has exceeded all my expectations. The support it offers is fantastic,whether I'm sleeping on my side or my back, it provides just the right amount of support. Plus, the material feels incredibly comfortable and breathable. Most importantly, the value for money is really impressive. I'm extremely satisfied with this purchase and would highly recommend it to anyone looking for a high-quality, affordable mattress. It's definitely a worthwhile investment!

After reading many positive reviews, I decided to purchase this mattress with high hopes. However, after laying on for less than 2 hours, I had to get up. My back, my butt, and the back of my legs all hurt terribly. This mattress is so hard its like laying on Concrete. That's no exaggeration. Terribly experience.

Not firm at all!! Very squishy and bouncy. When my partner lays next to me the bed pushes in so mush that I roll into him. Not happy with this bed at all but don’t want to go through the trouble of trying to find a box for it to return it.

When I moved the box I was pleasantly surprised at how heavy it was. As soon as I removed the plastic and unrolled it, it puffed right up. It's comfortable and can easily support my 200lb body. It feels as good as my last mattress which cost me $1000.
