I ordered and received the King Medium mattress, and it is by far the worst mattress I have ever purchased. Weighing around 160 lbs, I find it extremely uncomfortable. It is incredibly soft with absolutely no support. I never expected a medium-firm mattress to be this soft. I usually like Members Mark products, which was my main reason for buying this, but this one is disappointing. Not worth it—I'm returning it.

This mattress is way too soft. It deformed after just two months of use. Now it has a slope on one side. I contacted customer service thru chat and they said someone would reach out to me with in three days but no body reached out to me. I am long time Sams club customer. Used to spend thousands (which reduced by a lot when they started charging shipping for plus members). Very disappointed.

Wife and i were in the market for a new king size bed. Went and felt a $2,500 king hybrid ortho firm bed at one of our local mattress shops. My Wife loved it, and i hated the price tag. But at the last second before i purchased the bed she wanted she had a change if heart. So I took a picture of the bed she wanted, and found this hybrid bed that checked all the boxes for $500 at Sams. Holy momma, i cant tell the difference when laying on it, we absolutly love this bed. The firmness is perfect for us. The hybrid is so cool because of the little coils. When any of us move around in bed we can't feel the bed move, its so cool because of the little coils. We went from a plush king size to a firm hybrid and i don't think we'll ever buy anything other then something like this. We've only had it a few days now, but it seriously awesome. We wake up feeling wonderful as apposed to our plush bed where we would wake up aching all over our body. The box it comes in weighs over 100 pounds, i had to borrow my neighbors dolly to get the bed into the room. From there unboxing it and throwing away the trash was fairly simple. I was expecting the matress to have a weird plastic stench, but it has a pleasent clean/fresh scent almost like a new car scent. Its not harsh at all. I was also expecting to open the bed and have to wait a few days to let it fully stretch out or completely mold into itself. But i did none if that, i opened it up, put a sheet over it, and we slept on it a few hours later. I would recommend visiting your local mattress shop, finding a bed that feels good to you, then checking sams beds for something similiar. As you could imagine its a gamble because you havent laid on the bed you spent good money on from sams. But hot dang, we're glad we took the gamble and purchased this king hybrid bed. Wife and i would highly recommend this Members Mark King size hybrid firm bed. Good luck to you all.

I set a reminder on my phone to review this after having it a year. I went from a traditional mattress + box spring on a simple frame to this hybrid mattress on a zinus smart base, so that was quite a change. I have now been sleeping on it for a little over a year. I was used to sleeping on a pretty firm mattress for most my life but found as I've aged that I was waking up with sore shoulders and hips. I'm a side sleeper. This is much softer than I had but I don't find that bad. You sink in a little bit but you don't have a you-shaped impression in the bed like I've experienced on a straight memory foam mattress. That being said, it's a little more effort to roll over in bed. One thing I was looking for and got in this mattress was less transfer of motion when my partner gets in or out of bed. The traditional mattress had quite a lot of movement that could be very disruptive. I debated for a long time between the hybrid and full memory foam with being unsure if the motion would be a lot better with the memory foam. I really wanted the extra support of the hybrid so I was pleased at lack of motion transfer. I am overall happy with this bed and would recommend to anyone that does need a bit softer on the pressure points.

First, I much mention I spent weeks reading reviews and testing mattresses at well-known mattress firms looking at everything from $500 to $5000 (review is for King size mattress). Cost is not relevant, I'm 60 years old and want a good night's sleep without waking up feeling like I was hit by a car every morning. I was prepared to spill $5000 if necessary. Your body weight and sleep position have everything to do with the correct mattress for you. I am a side sleeper, 5'10" and weigh 185. Wifey is 5'4 weight 130 and also sleeps on her side and back. I am prone to hip bursitis (mainly from side sleeping), low back stiffness and sciatic pain when I lift and carry heavy things or have a strenuous day. I have also had a hip replacement two years ago. We had a 14" memory foam mattress with about 6" of varying layers of memory foam top on top of 8" dense foam. I began waking up every day feeling sore back, hips, shoulder, legs and feet so we decided it may be time for a mattress change rather than give into the fact that I'm old and this was normal. Everything I researched says my body size/weight needed inner spring support (hybrid mattress) with plush top. Thanks to the person who left a review thanking all the people who said this mattress is too soft. IT IS JUST RIGHT FOR A SIDE SLEEPER MY SIZE. I feel it is on the softer (plush) side and wife feels this way too. So far, the mattress has changed my life. I sleep all night in the same position and wake up without the aches and pains given by my old mattress. I used to wake and toss sides every couple of hours because of shoulder or hip pressure pain or numbness. I can now sleep on my hip replacement side for hours. The mattress also is very stable and does not wake the wife when I sometimes get up several times a night to use the bathroom. I use an adjustable bed frame and this 12" hybrid mattress conforms a lot better to the adjustable bed frame over the old foam-based mattress. BTW, I highly recommend an adjustable bed or anyone. Adjustable bed frames make reading, watching TV or just resting the bones a pleasure. We always sleep with our heads elevated slightly. I could not go back to flat mattress and dread sleeping in hotels for that reason alone. Check out Amazon, they are cheaper than you think. This mattress may not be good for people 200+lbs. But I do know this mattress is RIGHT for me NOW and hope it lasts 5 years. It is worth every penny and no need to spend $4500. I'll buy a new one every year if needed. Also, my smell senses are very keen and I have no idea how people think this mattress smells. If I had to guess, these reviews are fake from much higher priced mattress manufacturers. This review is real, I'm real and my wife approves of every word. King size mattress was purchased from Sam's on DeZavala in San Antonio, Texas. The box is heavy, get a friend to help.

I was not sure how I would feel about a bed I wasn’t able feel try in-store. The first night was not the best, but I don’t think I gave the bed enough time to set, it was a little too soft. The second night - wow. I was impressed with the comfort. The bed is soft but not too soft, and the springiness is great. It formed up nicely and is very comfortable. I recommend this bed.

All the reviews are promotional so don't trust it. This mattress smells horrible, strong and toxic. It smells throughout whole space and beyond. I left the doors and windows open all night to air out but the smell remains strong and concerning. As far as quality, I opened it up and it appears refurbished in some parts especially the springs. It's much more soft than advertised. It did open to 12' and the mattress cover appeared of good quality but even after washing it in hot water it's still smells toxic. Skip this one and go to a top brand mattress.

It's too soft. Medium to firm? Nope. Had it for about 4 months now.... It's so awful. The sheets fall off because there is now structure at the corners. Plus we constantly have to adjust the fitted sheet because of the smooth cooling top. Our heads sink even with our nice thick pillows. Back hurts.

This mattress checked all the boxes. It is the first mattress we have bought from Sam's. The quality seems good but we have been sleeping on it now for a few months and it is definitely too soft. NOT the medium-firm it says. I'll be looking to return this one and might need to look at an actual mattress store.

You don't know what you don't know. That's the way it is when searching for a new mattress online. But you'll be hard pressed to find a better mattress for the money. This is truly a 4+ especially if you're a side sleeper. I have slept on a Novaform for years which is a 7 firm. My shoulder and hip pressure points are really beginning to bother me. I bought this for my guest room and I have been using it a lot lately. Definitely a better mattress with a 5.5-6 firmness. A hint of "squishy" which might fool you into believing it's a hybrid. A solid buy.
