iKrema may be out of business according to customers. See our top mattress choices. iKrema is another brand of factory direct mattresses in a box. They offer two mattresses that are both memory foam. The lower end model is 10 inches thick and the higher end is one inch thicker with more cooling thermagel. Overall, their prices are similar on the lower end to other mattress in a box competitors. Their beds are made with CertiPUR-US certified memory foams so you won't have to worry about the effects of nasty off-gassing.
Sleep Science builds a line of latex and memory foam mattresses. Their claim to fame is their 'wedge' technology that provides edge support to every piece of the mattress. Additionally, they are Certipur certified, which means they have low VOC and no formaldehyde in their mattresses. They also use bamboo material in some of their mattresses. Their mattresses are made popular through their relationship with Costco warehouse stores where they are sold at a competitive price vs many of the retail sold mattresses of similar material quality.

Bowling Ball & Density Tests
Some online reviewers use the bowling ball test to measure firmness. These mattresses have good consistency in the feel of their surface layers, which is perfect for customers wanting to feel secure about support.

Customers had mixed emotions about these mattresses. Many report sleeping well throughout the night and having a good overall experience, but there were others who were not as comfortable. To make sure that one of these mattresses will work for you, read on below.
A supportive mattress is important to all, but especially important for back and stomach sleepers. Even side sleepers need gentle support to make sure their spines are aligned. These mattresses offer a good amount of support, above average overall. That said, some folks didn't feel supported enough so if you are heavier, make sure to take a harder look.
This mattress does well for most in terms of providing edge support. But, some heavier customers may experience some dipping close to the edges.
Finding a mattress that has comfort that lasts can save you lots of money. But, as companies focus more on making money, everything from clothes to bedding degrades faster. Customers give mixed feedback when it comes to the durability of these mattresses. Each mattress is different in how it affects you individually and may feel comfortable for you for years, but others have reported not being so lucky. Make sure to read some of the customer reviews before purchasing.
There was a strong odor for me on delivery that went away eventually, but I really hated the smell of the mattress at first!View More Reviews
It's a great mattress and super comfy! Though it does make it a little more difficult to get out of bed cuz you don't want to leave! Heard about this through a friend, found out they were selling on Amazon after I had already gotten mine. But definitely a good buy
Love this bed. Worth every penny. We get a great sleep every night. Easy transaction/delivery and helpful customer service.
I love this bed. Make me feel so good and sleep awesome.
Have not had any issues and have been sleeping really well. Ikrema mattress is super comfortable. my wife and I do not wake up each other up when move on the bed.
Absolutely LOVING the new mattress! I swapped over from a Tempurpedic memory foam mattress (about 15 years old now) and simply LOVE the new IKREMA one! Support with softness! YES!!
I have used the mattress in six months. first week I wanted to return because memoryfoam mattress is not good for me, but one week later than now I have good sleep. High quality mattress.
I love everything about my new mattress we purchased. Fast shipping and comfortable mattress. Since I got the mattress, I get better sleep than before. I have back pain issue, but the mattress reduce my pain.
Affordable!!! and Good quality When I have used this mattress, I could feel different than my old mattress. I do not wake up until morning, and I Enjoy sleeping on the mattress.
The mattress is perfect balance between firm and soft. I absolutely love this mattress. I have never slept in a more comfortable bed.
I really like ikrema mattress. Fast shipping and great customer services. I am 165lb, and side sleeper. The mattress is very comfortable. not too firm and not too soft.
Slept great the very first night. No achy pressure points lots of support. I did not like chemical smell cause i have allergy. i could not smell
We bought this mattress over a year ago...had no idea that they sold a separate foundation. Spent months replacing the bunky board we got from Crate and Barrell 2 times and dealing with back pain, even called the mattress mfr. The mattress mfr said they recommend their foundation instead of bunky board. Ordering it today, hopefully it will take care of the problem but paying $50 more than if I bought them together from the start. They need to update the description and recommend the foundation if they don't buy it separately OR don't even sell the mattress alone. Description said it needs a 'solid' foundation...what does that even mean? I had a hard time trying to find a bunky board that is solid wood from many retailers. Crate and Barrel's new bunky board is made of compressed cardboard! A painful process, but I like the mattress.View More Reviews
The mattress is definitely on the firm side but we both find it about right. After 11 months, the bed seems to be wearing very well... no signs of change in feel or shape. The adjustable bed is used in zero gravity every night for one of us and not used at all for the other. The adjustable bed works well for back sleepers but not side or stomach sleepers.
This bed is the best we have ever slept on, even 6 years later. We have the queen, and now want a Cali king (we now have a dog sleeping with us), and will be buying another one of these latex matresses from Costco. This one will go into the guest room, and it looks brand new. It has not settled or sagged at all, even though it is used every night, by 2 people. It is NOT hot, either. The memory foam mattress we bought from Costco first, was hot, however. So we returned the memory foam and got this latex mattress. We are so happy!!!
I did what i thought was plenty of research before i bought this bed.. I've waited a full year to try and get used to it, and kept telling myself and my spouse it would get better. Not only was it hard and uncomfortable but, from 3 months on, it had big depression on both sides. It seemed to get worse , not better! The only good thing is i bought it from Costco, so they agreed to take it back, no problem! Yea Costco!!
I bought this bed on July 7, 2016. It was my first Costco online shopping. As in warehouse shopping, the online service was very good. The delivery company did not call me to confirm the delivery time but Joshua and Carlos did great in the delivery of the bed and setting it up. Brandon at the distribution center was excellent. I could test the bed before the purchase. The latex mattress feels cool in summer compared to other types of mattresses. I hope I enjoy my bed for many years to come. I love shopping at Costco!!!
I've purchased 3 of these mattress so far. The first one about 3 years ago, then another one the following year and another one a couple months ago. the first one was in a guest room and the other two were for two of my kids who loved the bed when they slept on it while visiting!
I bought this bed over 2 years ago, maybe 3 years now. My husband was a reluctant buyer, because we are only early 40's :) He thought adjustable was for the nursing home. But he had enjoyed it just as much. It hasn't helped his snoring, but he enjoys the leg elevation and massage features after a tough day or workout, and elevation of his head when congested. I have had a couple of back injuries from car accidents, and sleep considerably better on this bed than ANY OTHER!! We had a memory foam before this. This is NOT memory foam. Memory foam sinks in with your weight, then when you turn over you fall back into the rut you created. Ours was also hot. This foam doesn't radiate heart back at you. I love that! It doesn't sink in. It has great support. It is nice to be able to sleep elevated without getting up in the middle of the night to prop up or go to the recliner. My bed sleeps just like it did almost 3 years ago. No sagging, indentions, or soft spots. It does creak a little when adjusting, nothing a little wd-40 can't fix. The base and massage features still work like a top. No problem! Good buy!
Purchased and received this split King organic mattresses with adjustable bases on April 8th, 2016. What a great product! Both my husband and I absolutely love our mattresses! The adjustable bases fit perfectly inside our existing bed frame, and the mattresses are sooooo very comfortable. I have always been a side sleeper, but no more! I'm able to easily sleep on my back now. Since I am a professional singer, this is a real plus for me. Also, the adjustability allows me to (among other things) raise my head ever so slightly to allow for sinus drainage as well as legs for additional perfectly tweaked comfort. The mattress cover is soft and also feels luxurious. A 3 inch layer of softer 19 ILD natural latex perfectly compliments the firmer 32 ILD layer underneath it to softly cradle with no pressure points yet support my body superbly. Adjustable base works great. Fully articulates for customization. Zero Gravity pre programmed position is heavenly! Don't wait. Buy this now!!! You'll be glad you did! Great price and great product. Thanks Sleep Science - Well done!
We got this bed a couple of months ago. It is very comfortable. Unaware another person is in the same bed. Mattress is fine for us, not too firm and not too soft. No odor.
Delivery company had great personnel.
One side had a control box (located under the bed) that failed in the first few hours. Costco called the company and we had a new one installed by the company in a few days.
I would suggest going to check out Dreamfit mattress covers (they come in twin xl and their kings sheets (2 twin xl bottom sheets with one King top sheet. Their bottom sheets and mattress covers have extra elastic straps to hold the sheets in place. I found these after much research. They stay in place great. Love my bed!!
The mattress delivery was great..even on time. The mattress itself is nice ...no sinking in like foam. Soft and supportive. The adjustable base is great. I do wish the lights on the remotes would come on before you try to poke the right button. Zero gravity setting is awesome!
Its very comfortable. Firm for support but not too firm. My wife & I think it is the best mattress we have slept in. No smell at all.
Disagree with the SUBJECTIVE product details 'Sleep Science comfort scale: medium with a bounce.'
There is missing objective ILD firmness scale info in the product details. For me, 5'3 and less than 120 lb, this is surely a soft latex mattress. In general, The 'soft' designation corresponds to an ILD rating of 19-21. The ILD rating for the medium range is 24-26. After digging yourself, then you find this mattress has ILD 19 on the top 3 inch layer over another 6 inch of 32 ILD.
