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.
Southerland has been in business since 1893, founded originally in Nashville, Tennessee where they still manufacture mattresses. They are most well known in mattress stores across the south and mid-west as a price-competitive option against many of the main brands. They offer a variety of mattresses under different brand names like Southerland, Englander and American Sleep. With both memory foam and pocketed coil options, most customers like their mattresses at first, but some customers experienced issues with durability.

There have been diverse feedback from sleepers about these mattresses -- both good and bad. Many folks enjoy their new mattress and are comfy, but there are some complaints. To ensure what one of these mattresses will work for you, take a look below for more information.
These mattresses are above average in their supportiveness, which is refreshing for those that need a mattress to align the spine. That said, some reviewers have mentioned support issues in reference to their bodies, so do some extra research to ensure that your choice works with your body.
Edge support is an indicator of how supportive the sides of the mattress are versus the center. These mattresses do well here, but some folks may experience less edge support over time.
These mattresses get mixed reviews from customers on their longevity. We all want to find a mattress that will be as cozy now as it was 10 years ago, but sadly not all mattresses last a long time. If a mattress with mixed feelings on durability is on your short list, double-check the trial and warranty policies to make sure you are comfortable.
Customer reviews can be hard to see from a high level -- especially with companies coming in and out of the market quickly. These mattresses, unfortunately, aren't scored as well by customers. There are still folks that are content, but others who are really not. Make sure to read on to figure out if they will work for you.
In terms of providing comfortable support for everyone, these mattresses get mixed reviews. Some have described them as supportive and report being comfortable, but others weren't able to get comfortable. If you are heavier than average, you may want to do additional research to make sure these mattresses will work for you
Edge support is the amount of supportive resistance you get on the edge of the mattress and is important for anyone that likes to sit on the side of their bed. Unfortunately, some may experience dipping while putting weight on the edges of these mattresses.
Sadly, these mattresses aren't well loved for their durability. While some customers felt comfortable with their mattress, others talk about problems with comfort over a short duration. If you are considering, make sure to read more reviews and go over the return policies before you buy.
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.
Best mattress I've ever had
The delivery was early by several days and happened without notice, but luckily we were home to receive the mattress. Unpacking and getting it ready for use was seamless and fast; we didn't have to wait for several hours and slept on the mattress within hours of set-up. So far, the mattress has been comfortable, relieving pressure in all the right places while providing support. I wake without the aches and pains I had come to assume were "normal" as I grow older. I am optimistic that it will continue to be as comfortable for many years to come.
We found this mattress to be extremely firm. We bought a softer topper to help but unfortunately it did not. We have purchased 5 other foam mattresses for ourselves and family members and had been very pleased. This one was just too firm.
Mattress is so firm and comfortable!
We picked this up because I have a bulging disc in my back and even though our other mattress was only 3 years old, it wasn't cutting it. I Love This Bed!!! We've only had a couple of months but so far so good. It's firm the way I need it and supportive. I'm a big guy 6'2 270lbs and it's great for me.
It’s a very good mattress and my mom loves sleeping on it. The mattress is true to the firmness.
Love it feels great for my back and gives plenty of support. Even better you don’t feel any movement when there’s someone next to you.
My husband and I both love this bed! It keeps us from getting overheated (a big issue of mine) and is the perfect firmness. This is our favorite bed after having two other gel cooling foam mattresses that have also been purchased recently. Actually, this is our favorite bed we've ever had and we are both 60.
Very happy with this purchase. Mattress is super comfortable and the firmness just right for both wife and I. (Of course firmness and comfort are subjective and very individual.) The adjustable functions work great and motors are pretty quiet. This was a major factor in our decision as my wife just now had shoulder surgery and sleeping in a reclined position is needed. Packaging and assembly are quality although it would be recommended for 2 people to carry base pieces and mattresses from delivery location to bedroom. Assembly video very helpful. Time will be the teller for durability, but very happy with the purchase and first impression.
the bed is comfortable but its been only 1 week since I have been using it.
Love my new Sleep Science split king bed and adjustable frame. I have only slept in in the last 4 nights so this is an early evaluation. We had a temperpudic for the past several years but this has surpassed that at more than half the cost. So far this bed is my favorite plays to be.
Don't waste your time and money . I had this mattress for more then a month. An every morning i woke up with sore Back .I am been using memory foam mattress for more then 10 years and I never had such a horrible mattress for the price i paid . I am glade i got it from Costco so I could easily return it ..
Good mattress that was delivered one month late. Came rolled up. Have to let it rest for 3-4 days to self inflate and acquire firmness. Since its brand new cannot say how long it will remain firm
Great bed! Sleeping great & elevate when needed without disturbing spouse.
Terrible mattress. Got it delivered after a month after it’s shipped (which is after a week after I ordered). Mattress has some stains on the bottom. Couldn’t spend another month and half without a mattress so opened it. Both Costco and sleep science have deceived me to the core and lost all the respect and trust I had in both these brands. It’s not firm at all, people who love plush would rate this below plush rating. I’ve no energy and time now to deal with the customer service at Costco which discontinued email and chat supports. Staying on phone with them for hours and getting mediocre resolution isn’t worth.
Sleeping was too warm and too firm
So far so good. Hoping for a number of years of the same. Attractive and comfortable.
Very good quality; perfect firmness and it’s a good looking matress.
Mattress was advertised as extra firm and we have found after 2 weeks of sleeping on it the areas where we sleep are already getting soft. Not sure if we will be able to keep it.
My new wife has complained about how much I enjoy sleeping (i.e. I occasionally snore) which apparently keeps her awake. I had a 10 year old sleep number bed that she despised sleeping on because she prefers a firm mattress (firm as in she'd be more comfortable sleeping on the floor than a soft bed) and I was more flexible. She'd mostly started sleeping in the spare bedroom every night because of these two factors when I saw this bed go on sale around memorial day. I figured why not give it a shot and if it didn't work out, we could always return it. Well right from the very first night she noticed a difference where I slept in the zzzz setting and didn't make a sound. That kept up for weeks until we took a small trip and stayed in a hotel room and the snoring returned. We both totally looked forward to coming back to our bed. I've been sleeping comfortably and so had she. Now we can both sleep together in peace.
Super comfortable. Easy to assemble with two people. We love the adjustable settings. Zero gravity is divine!
This is the most firming bed i ever experienced. May be too firm.
Excellent bed great support
It IS a from mattress of very good quality. The massage and adjustability of this bed are great. I’m hoping it softens some, I’ve had it for one month.
After 1 month we are very happy with the purchase. Firm but very comfortable mattress is exactly as described. Motorized stands work very well and seem to be high quality. The price was less than half of what we saw in bedding stores. We should have purchased sooner. My only comment would be that a set up and mattress removal service should be offered.
started great...slowly sank and now i feel like i am sleeping in a pothole. it went from good to worst really quick. not happy with this purchase but happy with costco policy. they are awesome.
I had the bed for 1 1/2 months, it served whatever expectation I have for this bed that's why we bought it. Me and my husband likes it a lot.
Sleep in this mattresses for one month. Good quality but just too firm for me.
Never had back issues till sleeping or rather trying to sleep on this mattress. Started sagging immediately. I am a small person. Should not be this uncomfortable. Broke down on edges immediately. Turned it ,tried everything. Do not buy this mattress. You will regret it.View More Reviews
This mattress started sagging only two weeks after purchase, both sides of the bed had deep indents in it causing both my husband and I back pain. I took it back to the furniture store where I purchased it from after 2 months, to be treated with the worst customer service ever. They inspected the mattress without taking off the plastic I wrapped in, stating they found nothing wrong with it. Poor quality, horrible comfort, and warranty. Save your money and keep looking.
I bought this bed only a couple of months ago and at first, it was a dream, but now it has a lot of sagging in the middle of it. If I only saw this review site before I bought. :(
Bought a couple of days ago. So far, pretty satisfied. Is it the best mattress? No. But, it's pretty decent. A little worried about the durability from these reivews.
Luckily was able to return this. I was really dissappointed with the material. From the get go, there was one area that poked into my back. It was a little strange and I thought that it may have been a defective product. But, after risking once, I won't be risking again.
I thought that I was going to be getting a real value out of this mattress, but uncfortunately, this is exactly what you would expect out of a cheap mattress. Something that leaves me in pain in the morning is exactly the opposite of what I wanted to purchase. I wish I could give 0 stars.
I got this bed in 2001 and am still happy with it. Every night I sleeping soundly and without any problems. I wish they made more exactly like this one!!
Great mattress, I bought one for my mom and she loves it.
The worst mattress I have ever slept on in my life. Within one month of sleeping on mattress, it's like laying in a fox hole. I regret not complaining immediately. I would give zero stars if I could.
Over 2 inches the mattress has sunk in less than 6 months. I am not a large person...rotated etc. Regret not taking it back within 120 days. Now..we are stuck. Jumped thru hoops for warranty...so we can get ANOTHER poor quality mattress.
Worst mattress I have ever owed! $1200 mistake
Terrible quality for the money. In less than one year we have craters where we lay and have done all the recommended turning of the mattress etc.
This is a wonderful company. They treat people very well with much respect. Would advise anyone to do business with them. They are honest and good-hard working people, who always keep the customer in mind.
The bed was bad after 18 months and back issues ensued at 36 months! Tried to get the warranty to cover the bed but they wanted me to pay $250 for them to complete the warranty.
We bought two sets of these, what looked like Big Lots mattresses. We were told they would be the same. When delivered they were two different types of mattresses. One was very cheap and after 3 nights it began to sink down a little. The next night it was worse. I have awaken with back problems each morning and in the middle of the night. Worse. CHEAP, set of what we told , was a wonderful set. $250 for warranty. Dear Lord, had we known. This true, negative comment will be shared all over the internet. LEAVE THESE CROOKS and their mattresses alone.
We purchased this mattress almost exactly 6 years ago from Nebraska Furniture Mart's mattress selection (in Kansas City 2012). The Southerland was presented to us as a Simmons equal, made by a proud USA company, and sold for less of a cost of most mattresses ($659.00). I've had a few years of restless sleep and segments of back pain, but I've been making other excuses for the problems (maybe gaining a few extra pounds, maybe stress, maybe needing to get some more exercise)...until now. I have had severe back pain while sleeping to the point it is constantly waking me up during the night and spasms upon waking. It's been months now and I finally gave in and have tried sleeping on my sofa and my child's twin mattress. Both have been better periods of sleep than in my own bed. The store I purchased the mattress told me today that in order for the company to uphold the warranty, and potentially replace the mattress, they would need to prove there is a 1.5" permanent depression in the mattress. In my case, the mattress has no depression when not laying/sitting on it. In my case, my mattress just doesn't seem to have the same strength of resistance to my weight when laying on it. I have a "Firm" mattress but when laying on the mattress I feel like I am in a long curved shape, putting a strain on my lumbar back curving the wrong way.
Started off great, by the end of the first year my husband was sleeping upstairs in the guest room. After the second year, I was sleeping in a hole. In order for them to even consider doing anything you have to jump through hoops and it doesn't show when it is just sitting on the floor. When you lay on it just hope you can manage to turn over or even get out of the bed. We have packed folded towels underneath trying to get some support but even that is breaking down. Haven't had a good nights sleep in a very long time. Any mattress you cannot turn will end up with a sunken place in it.
I bought an Englander Egel mattress that Southerland owns or makes. I've gotten such a run around from these all these people I don't know who is responsible. The mattress started falling apart after two years. I'm still trying to get warranty service for it put they keep handing me of to one person that handles the all the southeast US and he doesn't return phone calls or Emails. Do not buy from these people. If you have a problem they just keep passing you around hoping you give up! I'M NOT GIVING UP!
Mattress springs were poking through the padding within 2 years of purchase. The mattress failed and has a huge "nest" area that sinks about 4-6 inches deep and is about 12-18 inches across. I will never buy another southerland mattress. I bought this one to support a local company. NEVER AGAIN. The store I bought it from will not honor the warranty and say they no longer carry Southerland due to similar problems. I called and left numerous messages with Southerland's customer service - no one returns phone calls. I finally reached someone but when I sent the paperwork off to replace the mattress - NOTHING.
All I know is that ever since I bought my Southerland mattress at Bedzzz Express, I now know what it means to get a good nights sleep!
I purchased a mattress from a local store in 2014 that was a Southerland product. The mattress was great at first but became harder and stiffer after 2 years. The foam actually became less flexible. There is nothing in the warranty that covers this type of ware. Amerigel Discovery Gel - By Southerland Bedding, Queen, Medium Firm.
I purchased an Englander Egel mattress Dec 2012 and we loved it till it failed in Jan 2017 (less than 5 years). I filed a warranty claim and was sent another mattress by Southerland BUT it was a completely DIFFERENT mattress. Southerland has made no effort to resolve this issue. We are stuck with a HORRIBLE mattress that we will have to replace. I do not recommend this company.
After initial purchase 6 years ago the mattress was defective. For whatever reason Weekend only quit carrying their product. For a claim they quoted their fine print and could care less. The warranty price was like buying a whole new mattress. I would never waste my time or money with this group again.
It's a foam pillow top with springs underneath. For about one year, it was so comfortable. Then it sagged so bad, we got egg shaped pockets to sag into. I only weigh 110 lbs.
I bought this mattress from an auburn mattress dealer. It was a second one purchased. I felt like I got screwed all the way around. My back continually hurts and I have a mattress pad. I spent 3700 and hopefully I will buy another one from a more reputable dealer. The company should reimburse the customer and take the mattress back. Do not buy this mattress. Southerland was conveyed to be a great company and it’s not.
I thought I was crazy at first because the mattress is about a year old. How could it sag so soon? I am a small/skinny person and have an indent on the side of the bed I sleep in, I am trying to rotate it to have a fresh side. The problem is you can't sell a mattress to anyone else. I guess I'm stuck with it : (
bought Southerland Carly Plush mattress 6/19 it's not been a year and the mattress has a sag in the middle of it, and it's still not comfortable for me, unfortunately they are letting me replace it with the same brand name which I would have rather get a different Brand name like Serta or Sealy.. but $499.00 mattress is this what u get then I will have to go up in price for a better night sleep. I would not recommend buying this brand..
This bed is HORRIBLE. I purchased this bed for my then 6 year old daughter who weighed around 45 pounds. This bed lasted less than a year. It felt as if there was a hole in the middle of the mattress. I would have opted to return this mattress or voice my complaint, but the furniture store that I purchased it from had gone out of business. This bed reminds me of a taco. When you lay on the bed, it seems as though you are being folded. PLEASE DON'T PURCHASE, READ THE REVIEWS, MONEY IS TOO HARD TO COME BY! My daughter will opt to sleep on a pallet with blankets and covers on the floor or in the bed with me that sleep on her bed! This will be a POOR investment!
My 2020 Fairweather Mattress and Boxspring were delivered 9 days ago. I noticed the center of the mattress started sagging after 3 times trying to sleep on it. I went to Kings Furniture in Dayton, Oh on day 8 (yesterday), to complain, and inquire about an upgrade. I was told someone would call me today, and that I should've returned it within 2 days of purchase. I am financing this matters set for almost $900.00, and have spent half of my first week with it, sleeping on my sagging sofa. I'm super pissed, and I want out of this deal!
Lived in Nashville and figured I'd buy a local brand, big mistake. Spent the extra money on the "Ultimate Serene" Line . The only thing this "Ultimate" piece of junk has me saying is "Serenity Now". 3 years later I'm leaving the house to go sink another $5G on a new bed set up.
I've never owned a "Southerland Mattress" before, and this is the first time I have taken time to write a review. I purchased the mattress for my guest room, so that my elderly mother can sleep over when it's late. Since she initially didn't spend the night, I spent an evening "trying it out" to make sure it would be comfortable for her. I was very impressed with the gentle support, and comfort of the mattress (I fell asleep on it) After she tried it and commented "how well she slept" I decided to take some time to write a review! Thank you Southerland, for manufacturing such an awesome mattress!!
Do not buy a Sutherland mattress, it should have been recalled for faulty craftmenship! Don't buy from Johnson's Furniture in Newberg, they're crooks!
