Product description

  • Is this mattress too soft or too firm? Does it help with back pain?

    This is a medium-firm mattress, providing a perfect balance of comfort and sturdy support. It promotes proper spinal alignment, which is highly effective for relieving pressure points and alleviating lower back pain.

  • Does this mattress sleep hot at night?

    No! This mattress is built with highly breathable materials for maximum airflow. It efficiently dissipates body heat and regulates temperature, ensuring you stay cool and comfortable all night long without waking up hot.

  • Will I feel my partner tossing and turning? Does the edge sink?

    Not at all! It features advanced motion isolation, so your partner's movements won't disturb you. It also offers excellent edge support, allowing you to sit securely on the edge without slipping or sinking.

  • How long to fully expand? Is there a strong chemical smell?

    Please allow up to 72 hours for full expansion. There is no harsh chemical smell. You might notice a faint packaging odor upon unboxing, but simply opening a window for ventilation will clear it up quickly.

  • Does this mattress contain fiberglass? Is it safe?

    It is 100% fiberglass-free and lab-certified safe for daily use. If you need to verify our safety certifications,we are happy to provide the original documents immediately.

Great Mattress!

I got this King mattress a few weeks back, and I'm really pleased with it. It's comfy and gives solid back support; I noticed better sleep quality right away. The King size is roomy enough to stretch out and sleep well. The materials feel nice, and it does a job of keeping motion transfer to a minimum. It showed up quickly and in shape. Overall, I'm happy with this purchase and would suggest it to anyone in need of a comfy and supportive mattress.

Best Mattress Upgrade!

I used to struggle with sleep and back pain, but ever since I switched to this mattress, everything has changed! When I lie down, it feels like I'm supported just right—soft yet firm enough to fit my body perfectly, like sleeping on a cloud. It offers great support whether I'm on my back or side, and I hardly make noise when I turn over, so my partner isn't disturbed at all. The materials feel well-made and breathe nicely. I wake up feeling refreshed, and my back pain has really improved. Shipping was fast, and Colby was helpful with any questions I had. I can't believe I found such a great mattress at this price! I recommend it to anyone who cares about getting a good night's sleep!

Super comfy mattress, highly recommend!

I’m really impressed with this 10-inch memory foam and pocket spring hybrid mattress! It expanded quickly after I took it out of the box and had almost no smell at all. Setting it up was a breeze. The medium firmness is just right—soft enough to fit my body shape but still gives great support, so I don’t feel like I’m sinking in. I've had back pain in the past, but since I started using this mattress, I haven’t woken up with it. I sleep much better now. The motion isolation is a big plus too; the springs are silent, and I hardly notice my partner moving at night. Plus, it's breathable and doesn’t get too hot during the summer. Shipping was quick, and Colby was friendly and helpful, answering all my questions. Overall, this mattress is and offers great value!

Luxysea Safety and Comfort First

We got our bed sooner than expected, which was a nice surprise! Shoutout to Hawkins Woodshop for that great service. Sorry for the delivery team having to tackle those stairs—this package was heavier than I imagined. I also love that there was no extra shipping cost. Now, about the bed: it was a really safe and smooth experience compared to the last bed we ordered from another place. That one was a bit of a nightmare to unpack. I still remember how it sprang out of the plastic and broke my lamp! With this Luxysea hybrid box spring/mattress, they clearly put in a lot of thought to make the unpacking process safe. The way it was packaged was impressive. The outer plastic had little holes that allowed it to breathe and also kept it from bursting open like the last one. I was relieved that this time there were no surprises. They included a tool for unpacking, which I think I'll use as a letter opener later. Once I made a hole in the plastic, the mattress slowly expanded as the air got in—simple and effective. I pulled off the plastic, which is also high quality and can be reused later. The box? Our cat loves it, so I’m planning to turn it into her little playground. Luxysea has done a great job engineering this Queen size mattress with eco-friendly materials, and I appreciate that they’ve thought of everything. After one night, I can tell the firmness is just right for both of us—we’re already feeling better than we did on our last mattress. I expect to have a great relationship with Luxysea moving forward. Huge thanks to the Luxysea team for making sleep so much better for us!

The King size is just for stretching out and getting cozy. The materials seem top-notch, and it helps reduce motion transfer. It showed up quickly and in shape.

Exceeded my expectations

I've been using this 12-inch queen memory foam hybrid mattress for a few days now, and it's really impressive. The mix of memory foam and individual pocket springs gives just the right amount of softness and support. It fits my body well without sinking too deep, and I wake up pain-free, which is a big plus. One standout feature is how well it isolates motion. Since I share the bed, I hardly notice when my partner moves around or gets up—no more middle-of-the-night disturbances! Plus, it’s quiet; I don't hear any creaks or noises from the springs. Setting it up was a breeze. It arrived vacuum-sealed in a box, and I had it unpacked and ready to go in no time. It fully expanded within a day or two and had little smell. If you’re on the hunt for a great queen mattress at a decent price, I'd recommend this one. It's for side sleepers, back sleepers, or anyone wanting both support and comfort.

Great mix of comfort and support

I had some key things on my mind when I was looking for a mattress, like if it would sleep hot and if I'd feel my kids moving around on it. Here’s what I found: 1. The medium-firm feel is just right, comfortable but not too soft. 2. The pocket coils do a good job reducing motion transfer, which was a nice surprise. 3. The cooling foam is way better than my old all-foam mattress; I sleep cooler now. 4. It popped up to full size within a couple of days. 5. There wasn’t any strong chemical smell after unboxing it. Overall, it's a nice mix of support, comfort, and motion isolation for the price.
