Save up your money and buy a better mattresses. This is hot especially in summer heat in Texas. I wake up a lot burning up. This is owning it for 3 years and it's still hot. We are not looking into buying a coil mattress with no memory foam.

We purchased this mattress at our local Sam’s Club 16 months ago. We got it to replace a 10 year old Serta mattress that had been great to us. We read through hundreds of reviews and decided to give it a go for the price point and overall positive rating. We both have horrible lower back pain since getting this mattress and it continues to get worse. There are indentations/slumps in the mattress on both sides where we sleep. I have resorted to sleeping at the top and foot of bed where there aren’t slumps but still wake up every single day with lower back pain. We wanted to love this mattress, but unfortunately we wasted our money and will be replacing it with something of better quality. We trusted the Serta brand but sadly won’t be purchasing another one of their mattresses after this.

Purchased this bed and the mattress corner edges never expanded to full size, Sams told me in order to return the bed has to be in the box, but if it was a regular mattress I could easily return it without even bringing the mattress back mind blowing experience. Even though on the box Serta says it’s can be returned

This product is a memory foam & latex foam mattress. I don't believe it's a hybrid. I don't think there are coils in it. It comes delivered in something like a 2x2x4 cardboard box. The mattress is vacuum packed in plastic, folded in half, and rolled up. Once you cut it open, you have to let it expand for a few hours, even a day would be good. I would recommend that you don't throw away your old mattress just yet! After opening the new one, let it sit in the garage for 2 weeks prior to using, as the outgassing fumes are terrible and most likely not good for your health. After replacing the old mattress with it, you should run an activated charcoal air filter in the room for a couple months to take out the remaining VOC's that outgas.

This was a big disappointment because it was way too soft for medium size people. Did not help with back pain like my 17 year old memory foam mattress that I loved. Top foam too thick, felt like I was drowning in bed. Worst was the foam did not recover from body impressions. Had dips that showed badly, so I'm returning it to Sam's. The mattress cover is nice however, if that means anything.

Not sure why other people have had size issues but this mattress DEF expanded after several hours to 12". We did lay it flat on the low profile box spring and didn't sleep on it for a day. And another person saying the cover couldn't be removed to be washed is wrong...there's clearly a zipper for removing the cover on the bottom of the mattress. It doesn't get easier to buy than this...box has handholds and wheels so you just pull it to your truck or SUV and load 'er in! Slept great on it and for the $, it can't be beat. Sure, I had a $2700 Temperpedic full foam in past....but it was warm and while I dont sink as deep in this Serta as I did in the Temper, I didn't notice while sleeping or waking without any aches. SO...money saved and value received.

Sams keeps deleting my reviews! Recieved a used mattress with head stain, butt dip, and flattened side. Was in an unmarked box and clear bag that was shrink wrapped Now have to rebox which is impossible to return via fedex, or gl to sams club store to return a 125# mattress.

Had the bed for over a month and agree with the person that said it was fine for heavier people. I'm not sure if the guy that said he was 240 lbs was reviewing the correct mattress, but I'm closer to 300 lbs and there is very limited sinking and turning over is not a problem. Consumer Reports rates this mattress very high even among spring/foam fusions and the more expensive $1000-2000 beds. They even rate it a 7 out of 10 in firmness, which I agree with. If you are looking for something similar to laying on concrete, then maybe this isn't for you, but if you want something with mid-high firmness, you'll be more than happy with it.

This mattress is one of the best mattress I have every owned. The sleep has been pure bliss. I also bought My Pillow, pillow set with my new mattress. I never believed pillow's could add such a boost to my over all sleep quality. Between the mattress and the pillows, my sleep is now 'healing sleep'. I wake up rested without stiffness. I recommend this mattress, and if you buy one, add the My Pillow, pillows, it really makes a difference in the quality of your sleep.

Comfortable and sturdy
