Green & Cooling Tencel Mattress Cover

Sunrising Bedding 12 inch memory foam mattress cover is made from premium TENCEL fibers derived from renewable eucalyptus wood cellulose. What makes TENCEL fibers so desirable, aside from being a natural and organic material, are the revolutionary properties that are unique to it. TENCEL is softer than silk, cooler than linen, and absorbs 50% more moisture than cotton.

From Wood to Fiber
The cellulose, or ground pulp, used for TENCEL is dissolved in a non-toxic organic solvent. The solution is filtered through fine holes to produce fiber and the excess solvent is recycled in a closed loop process that it can be done indefinitely without degradation of properties.

The fibers are then immersed into another diluted solution that sets the strands, which are then washed in a demineralized water. Once the water is evaporated, the strands are finished and untangled. This revolutionary process has received the "European Award for the Environment" from the European Union.

Technologies inside

Our memory foam is made by adopting Variable Pressure Foaming (VPF) technology. Unlike other ordinary foams, VPF foam is made in a closed chamber where temperature, pressure and moisture are easily controlled. That's why VPF technology produces foam with consistent density, which makes it performs better than ordinary foams. 7,000,000 open but mighty-connected micro cells is combined with the foam. Those cells keep their form through squeezing out and breathing in air as pressure from sleeper changes.

    Awesome mattress! Was fully expanded in less than 6

    Awesome mattress! Was fully expanded in less than 6 hours firm yet extremely comfortable slept like a king!!! I highly recommend it better than a tempurpedic for much less money a great buy!!!!!!!!!!!!

    Healthy, unbelievable firmness and an outstanding value. My cheapest and favorite mattress to date.

    It’s only been a few days, but so far this mattress is quite comfortable and firm. I like it far better than the Luxi mattress that I returned due to discomfort and the quality of material and workmanship seems to be superior to the Luxi as well as the Luxi had unevenly cut pieces of foam. Consistent with its certification of purity, this mattress also had almost no unpleasant chemical odor when I unwrapped it.This is a mattress for someone who is tired of overpriced marshmallows and likes a truly firm mattress. I’d say that this mattress is at least a 7/10 in terms of firmness. You won’t beli… see moreeve how firm this mattress is without being too hard. That said, it will likely be uncomfortable for side sleepers but excellent for back sleepers and extracurricular bedroom activities. I have occasionally tried to sleep on my side throughout my life, but have realized that this has historically resulted in rolling over and morning pain across all mattresses. However, old habits die hard, and I have found myself trying to find a comfortable side-sleeping position on this bed to no avail. Just don’t do it.Overall, this mattress is truly great and makes my $1,000 Luxi look like, well, something that should cost way less than $1,000. Save money and improve your sleep- you owe it to yourself to try this mattress.

    Very pleased with our new mattress.

    This mattress has exceeded all expectations.? It set up so quickly, with barely any residual smells.? It’s really the most comfortable mattress I’ve ever slept on.? So much so that I just ordered another for a spare bedroom.? The price was hard to beat, it’s extremely comfortable, and set up quickly (on top of the box spring of our former bed set).

    Verified Buyer
    Sleeping happily ever after.

    Had a Tempurpedic mattress previously and loved it but it was $$$.? Thought we’d try this and it is awesome.? Much less expensive and the additional pillows were a big surprise.? They are our new favorites.

    Diamond in the rough!

    This mattress is so amazing for the price! It’s the perfect firmness and it has great bounce.? Best of all I didn’t sleep hot which being a big guy I was worried about.I allowed 48 hrs.for it to inflate before sleeping on it but you could sleep on it within a matter of hours.? When I laid down it was so supportive but not too firm.? I woke up feeling like I had blacked out for 8 hours, best sleep I’ve had in a long time.? For $400 this is one of the most under-rated mattresses out there

    Convenient Mattress Buying - Comfortable

    Very firm mattress but comfortable. It came packaged well – very compact. It was easy to set up on a platform frame and looks great. No box spring needed. Mattress buying made so easy!

    Incredibly comfy mattress! Worth every penny!

    Incredibly comfy mattress – It arrived in great shape and wasn’t too bulky or heavy for one person to deal with. I tested the mattress after giving it time (a few hours) to plump itself naturally to its 12 inch height (it arrived vacuumed- sealed to allow for more compact packaging). I also left it fully open for a few days in the room so that any slight odor (which I read might appear and would gradually dissipate) would be gone by the time I wanted to test it for comfort and support. I never noticed any any odor, (and I am very sensitive and allergic to many scents) . I tested it out on the … see morefloor and it was very supportive and I should mention I weigh 220 pounds! First of all let me just say it is super comfortable with the memory foam top layer, I was intending to originally make my own from Raw materials but I could not have done as good a job making it comfortable. I am so glad I found this mattress it was perfect for my needs. I would not hesitate to order another one for use in my guest room, it is a very well-made product that is super comfortable, portable and stores in a small space and the price was certainly worth every penny!

    Look no further for the best night's sleep you ever had!

    There is something awesome I must share with youI’m not an enthusiast of writing reviews of whatever product or service I get but this time round, there is something awesome I must share with you. It’s now a couple of months since an old campus friend of mine recommended a mattress that I had never used before. She knew me as someone who loved to relax on the bed during my free times hence the need for a “paradise” upon my body. What I would like to share with you is the ultimate experience am having with it. Unlike ordinary ones I used before that never meet my needs; this Sunrising Bedding U… see moreltimate Comfort 12 Inch Memory Foam is different. Why?Perfect BounceAs I stated above, am a person who loves to spend my free time in the bed to kick away that stress. Sometime it could get boring in the past because what I was sleeping on wasn’t gentle on my body. It could easily get me on the floor due to its forceful bouncing back characteristics. After purchasing this one, it’s like sleeping on a surface that understands that your body needs to be handled like an egg. It bounces so softly that you will love to stay there all day and night long since all undesired shocks are negligible. The other thing to mention about the bouncing aspect of this mattress is that it doesn’t affect the entire surface. It will just be upon you and the person sleeping next to you won’t be disturbed.You Can Turn As Many Times as You WantHave you ever experienced a situation whereby you have to look for that specific sleeping position for you to be comfortable? Well, you must have and it can be worse when you are having a partner. With this foam, that should be a thing of the past because am comfortable no matter which position I choose to sleep on. The appearance of my partner on the same bed does hinder nothing because we can always turn to any angle with maximum comfort in place.My Health My ChoiceManufacturers of most mattresses are known to use different materials in its design and some of them may not be good for your health. I mind a lot about my health and this doesn’t just stop on my diet but also other stuff that I’m using and this isn’t an exemption. When I buy any product, I will make sure that it has been approved and the good thing is that this one is for me. This foam is CertiPUR-US Certified meaning that am free from toxins that can cause allergies. Heavy metals are not found in this foam after being certified hence am less susceptible to life threatening diseases like cancer.Do you want to sleep as cool as me? This gentle foam that gives your body a tender touch is there for you. I have tried the Sunrising Bedding Ultimate Comfort 12 Inch Memory Foam and I can actually attest that it’s the best deal for everyone. That’s from me to you!

    Great mattress, I wake up feeling great

    Great mattress, I wake up feeling great! My bad back doesn’t bother me when I sleep on this mattress. Soft but supportive!

    Verified Buyer
    The pillow is amazing. The matress is soft, but the smell sticks.

    I love sleeping on the mattress. I am very thankful it came with a free pillow because I feel like they compliment each other so well and make my sleeping experience more comfortable.In my opinion, the bed is soft with durable material.Nevertheless, I can’t give it five stars because of the smell. I have had the mattress for about two weeks and the smell is still strong and it infiltrates the bedsheets and covers.I will update the review if my opinion changes as the time passes.

Questions and answers of the customers Back to product

  1. A Sunrising bedding is high density fiber fireproof lining without adding chemical flame retardants and through Texas 1633 CFR certification, each mattress of sunrising bedding collocates ?law label . The high density fibers are also used in body armor lining.
  2. A Hi, Generally speaking, our mattress suits any bed frame or bed base as long as their size can match. In the two options that you offer, we personally recommend the platform bed with slates, which is heavier to keep your bed stable. But as you have noticed, smartbase is a better choice for tight budget and suitable for people who usually move beds around. You can get one of them according to your own needs.
  3. A Yes, it fit well with adjustable base.
  4. A I have had it now for about 6 months. Still loving it. Great use of my money.
  5. A It's very okay. The mattress will not be affected a bit even after you leave it in the box for 6 month! We've tested it for you!
