Just Right Designs Made A Better Mattress Just Right Designs Made A Better Mattress

1. Luxury Cool & Soft Mattress Cover

Cool movable and washable mattress cover made of fabric that is cool to the touch, regulates heat at an ideal temperature all night long, even on those 90 degrees Fahrenheit nights. It is anti-pilling, anti-bacteria and mites. OeKo-TEX Certified.

2. Fireproof Barrier

The Fireproof layer is made of the same fabric used in bulletproof vests, it does not contain any Glass Fiber or flame-retardant chemical additives. CFR1633 certified to protect against fire.

3. Open Cell Memory Foam 2.5"

The Open-cell Gel Memory Foam is proved to sleep 25% cooler than traditional petroleum-based polyurethane.

4. Bamboo Memory Foam 2"

Bamboo charcoal eliminates odors, absorbs excess moisture(if you live in Louisiana or Hawaii, definitely give this mattress a shot), regulates temperature, and is an excellent choice for people with allergies.

5. Gel Infused Memory Foam 1.5"

Gel memory foam wicks away heat, keeping you cool throughout the night. Adding gel microbeads to memory foam increases the density of the memory foam as well, creating a surface that's soft, yet firm. You won't experience that hot, sinking feeling.

6. Durable High Dense Base 6"

The high-density core base support foam keeps the mattress from deformation, collapse, and provides unparalleled support during the night.

Pleasantly surprised and BEYOND PLEASED with this purchase!

Last month, after mulling over mattress reviews, I bit the bullet and ordered these mattresses for a guest room. I was concerned after reading some of the reviews with packaging and shipping issues but decided to go for it. Mattresses arrived on time, inside of their boags with none of the packaging issues that others had mentioned. We unpackaged the mattresses, mattresses expanded, mattresses are great, end of story… Only it’s NOT the end of the story! After a visit from my mother in law and her telling me it was the most comfortable mattress and the best night’s sleep she’s had in a very long time, I decided to try it for myself. And then my husband tried it. That was a month ago. Our $2500 mattress set in our master bedroom hasn’t been slept on for a month because we’ve been sleeping on these guest room mattresses. They are just that comfortable. Supportive, but easier on aching shoulders and hips and relieves pressure better than our expensive master set.

2 Reviews: A Back & Side Sleeper's Experience

Our shipment arrived with only minimal damage to the box and the mattress in perfect condition. We placed plywood on our existing 20 year old box spring to give the mattress added support. It expanded to 11" almost immediately, and to 12" within the next day or so. There was very little smell, which dissipated within a day (and I’m sensitive to smell). We waited nearly a week before sleeping on it. My husband, who is a back sleeper liked it immediately. Me, a side sleeper, hated it and got NO sleep the first night. It was just way too firm for me…..not plush at all. Either I began to adjust or the mattress softened some, because things seemed to get a little better with each night that I slept on it. I contacted Acesleep and was told it takes about 2 weeks for the mattress to contour to your body. I ended up placing a 2" foam topper to add some softness, and that did the trick. With the added topper, the mattress is now soft enough for my comfort, yet firm enough to support the backsleep in my bed. And, I really like the feeling of the softness we have on top, but the firmness I can feel right underneath. For the cost of the mattress, plus the $50 topper, I think the purchase was worth the investment.

well worth the money...

After years of sleeping on a traditional spring mattress my wife and I decided to try memory foam. As we researched cost, quality, and reviews we came to the conclusion that we has no more confidence in buying than before we started. Some people liked, some people hated. long and the short of this…..We took a chance…With some concern of purchasing one king mattress and not liking it, I decided to do a split king…So I purchased 2 12 inch twin xl mattresses as well as 2 split king Blissful nights adjustable frames. total cost 1400.00 I figured if one of us didn’t like the mattress it would be less costly to replace an xl twin than a king mattress.needless to say replacement will not be necessary. Although they are sold as a medium density mattress, after the full 72 hrs of expanding they sleep like a firm. A very comfortable firm. Almost perfect for both side sleeping and back sleeping.I did not notice the smell that people are talking about nore the expansion (uneven) issues…Everything from a quality stance has been perfect. The cool memory layer certainly works for me. I usually sleep with a light blanket and a fan, so a hot foam mattress was definitely a concern. haven’t woke up hot yet. In fact It worked so well I upgraded my feather pillow with a cool gel memory foam pillow….Love it!Although I’m only in the first few weeks of my Memory foam experience can’t attest for how long this comfort will hold up, at the moment I’m more than happy with cost, quality, and sleep comfort at this point. Acesleep garrantees limited 15 year the split king set up that allows my wife and I to adjust our mattresses independent of one another.My overall experience has been fantastic…Would highly recommend this set up fore anyone looking for a better nights sleep…From what I have seen My set up would have literally been thousands more with any other brands….

Wonderful Mattress!

For all of you who have never owned a memory foam mattress, the mattress comes hard and you have to wait 2-3 days for it to expand out of the box. This mattress took about a month to soften but it is so comfortable. It softens with body heat to fit your body. Also, you have to buy a mattress protector before sleeping on it. The zippered kind make the mattress as hard as a standard mattress and makes you sweat. So I always buy a waterproof quilted mattress pad. It is comfortable and doesn’t make you sweat. It protects the top and sides. Any spills go straight in and you can’t get them out. You can’t use a carpet cleaning machine on memory foam or any other liquid on it . You can only blot a stain off. Any stains void the warranty. I have been told by pest control that you probably won’t lose it to bedbugs but ask a pest control person. Rotate the mattress every month but never flip it. Flipping will ruin these kind of mattresses. I have to be in bed almost 24/7 so I bought the 12 inch bed thinking it will last a good long time. It is so comfortable. I have a hospital bed-twin XL but didn’t think about the added height and thicker/taller sheets to fit the mattress. I also use a regular mattress pad. My inseam is 31 inches. So I had to buy step stools to get into it easily and deeper pocket sheets or queen size cheaper sheets. Oh well. If you are more active you won’t need the step stools. Also, with my adjustable frame doesn’t work as easily as with thinner mattresses. I found that I don’t need to be adjusted as much either. I could not afford any these other kind adjustable frames. They might work better. Overall, this mattress is one the best ones I have owned for the amount of money. If you went into a bed/furniture store this would be about three times this amount. I have a lot of health problems and pain and this mattress takes care of the pain and allows me to sleep comfortably. I will probably buy this brand in 15 years when this one wears out. I have owned this mattress for 4 months now. I waited this long to see how it would do before posting a review.

  1. Nope! You should have wooden slats across your bed frame. That is the best support for this mattress.
  2. If your referring to weight, I'd say about 400 lbs between 2 people.
  3. If you want two you need to get the twin xl Matteress x 2 that s will make your king
  4. I didn't get the platform. Just mattress 14 1/2
  5. It is when using regular sheets. I use flannel in the winter and it keeps the bed warm.
  6. The size of the box is approx three feet high and about two feet deep. Quite heavy but not sure of exact weight rating. The mattress is vacuum packed inside two bags.
  7. It allows each persons body to sink in individually and the mattress keeps its shape. It doesn't sink in or cause you to pull apart. I have also noticed that it keeeps its shape perfectly. My husband is disabled and is in bed about 12 to 15 hours every day ( which is why we bought another mattress) and the mattress looks the same even after using it for four months. Highly recommend!
  8. all the reading i have done says that "foam" bed should be on a solid surface. or slats , no more than 5" apart.
  9. Mine didn't. I was so pleased. I don't remember exact time, but it was under two weeks.. I purchased twin size and love it!
  10. No it does not. You have to purchase the frame separately. We got a platform for it. Absolutely love the mattress.
  11. No sagging issues what so ever. I'm at 220lbs 6'2. Mine sits on a heavy duty platform frame. Best sleep I've ever had. Firm but completely comfortable. I fall asleep in less than 3 minutes.
  12. I do not have mine set up in an adjustable frame...but yes it is.
