so soft and comfortable

The Windosier 12-Inch Queen Size Mattress is a fantastic choice for comfort and quality! The hybrid design with gel memory foam and pocket springs gives the perfect balance of softness and support, making it great for pressure relief and reducing motion transfer. The cooling technology really helps keep the mattress comfortable through the night, and I sleep much cooler than before. It arrived conveniently in a box and was easy to set up, expanding quickly with no strong odor. I also love that it’s CertiPUR-US certified, which gives peace of mind about safety and quality. Overall, an excellent mattress for a great night’s sleep!

Ready to use right away

I was happily surprised by the support from the inner springs in the mattress. I greatly enjoyed the unwrapping of the shrink wrap on the mattress. It unrolled and expanded in about 15 seconds. I wish I had the camera rolling. They give you a safety cutter that looks like an envelope opener to open up the wrapping without cutting into the mattress itself. It fully expanded and was ready to use right away. I did not have to let it sit before I could sleep on it. I sleep on my side and had been waking up with my hip hurting every morning. This does not happen on this mattress.

When i first bought this mattress, I was a little skeptical. i mean, mattress in a box, How good could it be, right? i was wrong, though. it is comfortable, soft, firm, and one of the better ones i have. It is a good price and quality. Don't let the box fool you!
