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.

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.

We were looking for a plush hybrid mattress and came across this "medium firm" one. I read the reviews that it's actually soft so we decided to try it. My opinion is that this mattress is both. It has a very soft top layer with a very supportive foundation. It's perfect for us, both side and back sleepers. I feel that it's the perfect mattress if you're having trouble with pressure points at your hips and shoulders. I would've never considered this mattress with a medium firm description but thanks to the negative reviews I changed my mind.

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.

This mattress is ok. I've had it for a couple of years now and tend to sleep in the same spot because my child and dog also sleep in my bed a lot. I am noticing that the area I usually sleep in is starting to have a different firmness than other parts of the bed. I was hoping that it would last a lot longer.

This mattress is not medium firm! It is way too soft. Caused the worst lower back pain that almost had me crippled. This thing went back to the store. Return process was a nightmare because it was a huge king size. They couldn't get it through the door! Had to open the side panels of the door. So embarrassing!! Do not buy this in the store because if you want to return it then it is up to you to get it back to the store. I brought it home in a box in my small SUV. I had to borrow a truck to return it. Ugh

I bought this for my teen. He LOVES it. He said he is having problems getting out of bed for school in the morning because it is so comfortable. This is definitely not a firm bed. It's like sleeping on a cloud. I bought the 1st one because of the too soft complaints which means it would be perfect for him. My 12 yr old had to have one once he tried his brothers out. Now my teen daughter is begging for one. I might have to get one for myself as well. We have had the 2 mattresses for over 2 weeks. You don't feel any springs and the memory foam forms to your body so perfect. When unboxing it the bed fluffed right up so fast so we didn't have to wait to feel the comfort. Amazing. I am buying more of these

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.
