Firm but comfy
It is more firm than expected but still significantly comfortable because it is memory foam. A corner did not completely inflate but still is a good mattress

Amazing Memory Foam Mattress – Best Sleep I’ve Had in Years!
I am absolutely in love with this memory foam mattress! From the very first night, I noticed a huge difference in my sleep quality. It arrived tightly packed, expanded quickly, and had almost no smell at all. The mattress is perfectly supportive but still soft and comfortable. It molds to my body, relieves pressure on my back and hips, and I no longer wake up with stiffness or pain. I also love how it absorbs movement — when my partner moves, I don’t feel anything. Another big plus is temperature control. I usually get hot at night, but this mattress stays cool and breathable. The quality feels premium, the cover is soft, and it looks very modern and clean. For this price, it’s an absolute steal. Highly recommend to anyone looking for better sleep and real comfort!

Comfortable and firm!
I’ve been using this mattress for a few months now it’s extremely comfortable. It’s firming enough to where your back doesn’t hurt and it’s the perfect size. The memory gel is soft as well. Looks classy and is great for your body and posture. I have slept like a baby! Much better compared to my past mattresses!

Extremely Comfortable and Great Quality!
I’m really happy with this mattress! It’s very comfortable and has a great balance between softness and support. The memory foam conforms nicely to your body without making you feel like you’re sinking too far into it. I’ve been sleeping comfortably and waking up feeling well rested. It expanded nicely after opening and feels much more expensive than what I paid. Great mattress for the price and I would definitely recommend it!

Getting a good night's sleep is not a luxury, it's a biological necessity. After testing various brands of "box mattress," Gelsea's 12-inch model with Green Tea infusion stands out for a specific reason: the balance between orthopedic support and thermal freshness. In climates like Los Angeles, a cheap foam mattress usually traps heat; Gelsea has solved this with its open cell structure.📊 Critical specifications12-inch thickness: Three layers of progressive density that remove pressure points on shoulders and hips. Green Tea Infusion: Acts as a natural odor neutralizing agent, keeping the mattress cool for years. CertiPUR-us Certificate: Zero harmful emissions, safe for families and children. Motion Isolation: If your partner moves, you don't feel anything. It's the litmus test of a high-end King Size.💡 Single Expert RecommendationIgnore the 24-hour rule. Although the manufacturer says you can use it soon, to ensure the integrity of the 12 inches, you should let it expand for a minimum of 72 hours without weight on top and with an open window. This allows the foam molecules to regain their full structural memory and the residual aroma of compression to disappear completely.⚠️ Risks detectedMedium-High Firmness: If you're looking for a mattress where you sink like a cotton cloud, this one isn't for you. It's designed for those who need real support in the column. Package Weight: In King size, the box is extremely heavy. Don't try to move it alone; you risk a lumbar injury before you release it. Soft Edges: Being 100% foamy (without springs on the perimeter), sitting right on the edge offers less resistance than a traditional mattress. Great quality. Awesome value for money.

Great value, Firm Mattress, No smell!
The mattress was delivered tightly rolled and folded in half! It starts to expand immediately so I recommend having it in place when removing the plastic! It took about 4 hours to expand. The corners took a little longer, I think the mattress cover was preventing it so we just worked with the corners a little until they fully expanded. This is a medium/firm mattress, more on the firm side in my opinion, if that is what you are looking for, this mattress quality is great especially for the price point! No smell and I can tell it has the cooling gel! It measured exactly to a King size dimension and right under 12” for the thickness!
