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.

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.

So, I just bought this mattress for a roommate who is coming to live with me tomorrow for a few months. The mattress arrived 3 days ago, so I had to try it out myself. I'm not going to lie, I was skeptical at first when I went to lay down because it felt soft and I'm a firm bed person! However, when I sat up in it and was propped up by my back rest pillow, I quickly fell into this deep sleep sitting up while I was watching TV. I woke up at 4:00 AM and was extremely surprised to see the lights and TV on. I never fall asleep sitting up. I just felt so comfortable and so tired that I fell asleep where I was. So, after I woke up, I put my back rest pillow on the floor and put my head on the pillow and fell back into this extremely deep comfortable sleep and did not get up once to go to the bathroom! That is very rare for me to do that. The mattress molds to your body, doesn't smother you, is cool and feels soft, yet it's firm! (JUST RIGHT)! It feels so right that I don't want to get out of bed in the mornings. I just want to keep hitting snooze! Hahaha! Most importantly, I am 46 years old and have lower back problems, especially when I get up in the morning. Well, it must have been my old mattress because I easily got up from this new mattress (due to the way they make the outside rim of the mattress) and right onto my feet and had absolutely NO back pain! I felt refreshed and felt like I had a great nights rest. I am truly amazed! I have been sleeping in it for the past 3 nights now and I have to give it up tomorrow night:( I was so bummed about having to give it up, that I had to order a Queen size "Member's Mark Hotel Premier Collection 12" Hybrid Mattress" for my bed! Haha! I am super excited about it and I am super excited for my new roommate to try it out and see what she thinks about the mattress;) It is a great quality mattress and you can't beat the price for that kind of quality! 5 STARS!! Worth every penny!

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.

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.

The best mattress I have slept on by far! The memory foam on top of the mattress is a cool gel and I feel it first thing when I lay down. This was an important part of my purchase as I often get hot at night and wanted a bed that would keep me feeling cool. So far I've only have for 5 days, but I look forward to going to sleep every night on my new mattress : )

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.

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 is probably the worst mattress I've ever had. It has zero support and if you're a stomach sleeper then your spine will absolutely not like you. I wake up with back pain nearly everyday. It lost ANY and ALL support within 6 months of purchase. Buy a different mattress.
