HIMMLINE Medium Cooling Memory Foam Hybrid Mattresses in a Box with CertiPUR-US Certified Foam

The mattress arrived in a box that was falling apart upon receipt. I found no damage on the mattress but it had a very strong chemical odor. Once the mattress was unwrapped and allowed to fill out it was a pleasant surprise that it was as deep as advertised. The support of the mattress could be described as medium to medium-soft and I’m not sure how long it would last if used daily. After five days of airing out the mattress the strong odor had dissipated greatly. For use as a spare room daybed this mattress should work out satisfactorily.

This is a great mattress. It’s not too firm and not too soft, just right. It was very easy to take out of the box and you have to unwrap it a few times and it just rolls right out with ease. It’s super comfortable. I would definitely recommend this.

This mattress was exactly what I was looking for. It came well packaged with clear instructions to be mindful when opening. I let it air out and go to its full form over the course of 48 hours. Its very comfortable and seems to be a great cooling mattress as well. I feel like it regulates body temperature really well. Highly recommend.

This mattress is pretty amazing. I purchased the king size, and it arrived all rolled up in the box shown. The directions requested to open the mattress packaging with a special tool, which I used. Being so rolled up tightly, I wasn’t sure how a king size mattress could possibly come out and be comfortable. I had to double check the box said “king” before opening to make sure I received the correct size. Sure enough, upon opening the mattress immediately puffed up and inflated perfectly. The mattress had no smell at all, and is medium just as advertised. I was surprised it had handles and a pillow top for comfort. It advertises “cooling” as a feature, that is the only thing I have not yet noticed upon sleeping on it. Although I am not uncomfortable at night, so it must work. Impressed by this mattress, it’s comfortable, sized right and shipped fast! I recommend!

Purchase this mattress for my son’s platform bed! Great buy! It was shipped in a box that was easy to get into my home and an easy release once out of the box. My son sleeps very well on it. It was a good purchase.

This mattress is heavy and solid. It comes in a box, shrink wrapped. It’s best to open it in the room you want it in because it does inflate pretty quickly (learn from my mistake). This mattress even has springs for more support. Recommend this mattress!

Bought two for my teenage boys and they absolutely love the firmness! They find them very comfy and they were super simple to set up.

Been using this mattress for a few weeks now, and I can confidently say it’s perfect for those who prefer a firmer sleeping surface. The support is excellent—it keeps my spine aligned and relieves pressure points, especially around my back and hips. If you’re someone who wakes up with aches on softer mattresses, this one might be a game-changer. The build quality feels premium, and it has a sturdy, durable construction. While it’s firm, it’s not hard; there’s just enough cushioning on top to provide comfort without sinking in. I also appreciate that it doesn't transfer motion much, so sharing the bed is a breeze.

This mattress is very comfortable and I love it. The quality of it is very nice and soft, it is very comfy to sleep on and was very easy to setup and handle.

This mattress is very comfortable. Usually it take me a while to get used to a new mattress but for this one, I slept on it like a baby on my first night. It is perfect softness for me. It is exactly what I need for my bedroom.
