When we set it up it felt like we were laying on something hard, so I unzipped the cover only to find that they had put the mattress in upside down, and we were laying on the coils. I hope that's not what they do for all mattresses. We flipped it over, and rezipped it, and initially it felt comfortable, but by 2nd & 3rd day my lower back was killing me. We will be returning this. I would not recommend to anyone that could suffer back pain.

Wow! I was super worried about purchasing a bed online without trying it out. I have to say this is a great bed. we bought the firm version and it is perfect. It has all the features of a bed 30-40% more expensive. The firm bed is perfect for me (side sleeper, 200lbs, 6'5) The part that really sold me is Sam's return policy. They let you return at any time with no restrictions. I didn't return the bed because it was perfect, but I felt sure with my purchase!

We bought two twins a couple weeks ago (firm for husband and medium for me) for our king size platform. I really couldn't be happier, and my husband likes his, too. We both slept better immediately. Less tossing and turning from him, and I wake up in the same position I fall asleep in, with no extra stiffness/soreness. My only complaint is that when we measured (twice!), the twin x 2 was the correct size according to the chart, but now that they are here, unwrapped, and inflated, maybe the twin XLs would have fit a little better length-wise? Not a big deal for us, though...the foot of the bed is covered in sheets/blankets anyway, so it's not worth time or effort to exchange over a couple inches...but this is just a heads up for others who have different taste in firmness levels and want to try doing the same. Wait for the occasional $50 off and splurge. I think these mattresses are definitely worth it!

We ordered 2 Twin XL mattresses. Boxes claim to be Twin XLs but when we opened the boxes and allowed the mattresses to expand they measure as a regular Twin size mattress, 5 inches shorter than a Twin XL. All tags on the mattresses claim to be Twin XL.

Overall the mattress is nice and comfortable, however it is not a true king size mattress. The specs on the website list it as being 76x80, but it is only 77" long. When I put it in the bed frame I noticed a large gap at each end compared to our old mattress. My feet hang off the end. I guess that's how they offer the Sam's discount by removing 3 inches from every mattress.

If you buy the Ultra Plush, expect a SUPER SOFT mattress. In fact it is so soft, it feels like it is actually hurting rather than helping since there is virtually no support. We like a plush mattress but this is nuts. When you lie on it, and we are not big people, from the side you can only see 80% of us. Medium firm is probably the best. The other issue is sheets staying on. The cover is incredibly slick and the sheets slip off with ease. You will need a zip-on mattress cover that has some friction to keep the sheets from slipping off the corners. All it takes is getting in the bed and a corner will come off. We have the right sized, deep pocket sheets (from Sams). If your weight is in the 100 to 120 pound range, you may not sink like a rock. An average adult (I weigh 190), I am in a hole. This one is going to being returned.

I was initially reluctant, but I am pleased with my recent purchase. I have had split king purple 4 mattresses for a while now, but I wanted to switch to a single king mattress. I'm a 180 pound male who likes a softer feel mattress, and the plush version suits me perfectly. It's has just the right amount of cushion to keep my shoulders from hurting for when I want to sleep on my side, and just the right amount of support for when I want to sleep on my back. I caught this with a $200 off sale, and I believe the quality for price is definitely worth it. I purchased a 4 Way Stretch Micro-Knit fitted sheet for this and it stretches, stays tight, and stays put. No cons so far.

I got this to replace a mattress that cost about 3x this price of this one. I was leery to order something I hadn't laid on but read that Sam's has an awesome return policy, so it felt low risk. It arrived within a couple days. I was nervous that a mattress with springs would be rolled up in a box. However, once I cut the plastic off, the mattress decompressed and seemed full height within minutes. I did smell a slight chemical off gassing the first night, but not after that. I am really pleasantly surprised with this mattress... compared to my expensive one, which was also a hybrid, it is just as comfortable, has the perfect amount of give with the memory foam, but the support of the spring base. I got the medium. I have been sleeping great. I am a side and back sleeper. It has not seemed to sleep hot at all... if anything, it feels a little cooler. I would say the sides are maybe not as reinforced as my $$ mattress, but that's not a big deal to me, as I don't sit on the side of my bed for anything. I am waking up with ZERO back and hip pain, which is why I replaced my mattress to begin with. I was having SI join pain, tightness all down my legs and even in my obliques (I am a fit 45 year old female, 5'3" 120 lbs). I was beginning to think it was just some aging aches and pains, but am just so relieved to have zero pain now!

This mattress is wonderful!! First good night of sleep in months. We both woke up rested with no back or knee pain. Should have gotten this a long time ago. Came well packaged. If you need to get some excellent sleep. You have to try this mattress - you will not be disappointed.

The mattress is great. More of a medium firm, but plenty of give and bounce being a hybrid with foam vs latex. Will update if after a few weeks there are any issues. Ships from the same factory as nectar and the other popular hybrid mattresses. FedEx has yet to deliver a single Sam's club order by the original estimated date. Ever. I would like an option to choose a different shipper.
