Mattress is super comfy. I am 5foot 8 175 pounds and it is a perfect mid support mattress. I am a side sleeper and if the mattress is to soft or hard I wind up with back pain. I have had no pain with this mattress. It would be a 5 star but the workmanship on the mattress leaves a little to be desired. The cover you can tell was accidentally glued to the mattress in some spots causing the mattress to not rise completely. Also the cover is a little to large for the mattress making it too loose for the mattress. Like any foam mattress it smells awful for about a day or two till the smell goes away. If they can get the quality up just a little on the build it would be a 5 star

If firm is this soft, I would hate to imagine sleeping on the ultra plush. This mattress is so soft it is ridiculous. softer than my soft old foam mattress. returning as soon as possible. if you like soft mattresses that come delivered in an easy box rolled up- this is for you.

So my partner and I originally purchased this one mattress in 2020. At the time, it was the most incredible mattress with great support- we couldn’t believe it was only $400. After owning it for two years we noticed the mattress wears down a lot quicker than what a mattress should and wanted to exchange it thinking it just may be a minor defect. Sam’s club was kind enough to exchange it for us behind their member mark lifetime warranty guarantee. When we got the new mattress we immediately could tell that it didn’t feel the same as the original one we purchased. We have it it a chance thinking it just needed a few days out of the box but unfortunately it just wasn’t the case.

We hated this ultra plus mattress. It's like molasses for the top 3 inches then hard as a brick underneath, which doesn't work for a side sleeper with hips. Returning this has been a NIGHTMARE, 3.5 weeks of Sam's telling me someone would contact me to pick it up. Finally I get a call from some company I've never heard of and I have to wait another week. They were supposed to pick it up but waited to contact me that day to ask for a picture of the mattress. They finally showed up in some random pickup the next day. It's been 2 days and I still haven't been credited for my return. I've been calling Sam's all day and they keep hanging up on me. I contacted the company that picked the mattress up and they say they emailed Sam's, but Sam's acts completely clueless. Now I'm still fighting to get my money back and I'm absolutely furious because Sam's had a junk removal company pick up the mattress. They'd rather send a brand new mattress to the landfill then let me donate it to charity. We are so done with Sam's, they suck.

The mattress is fine, but Sam's Club needs to read this: Fed Ex Ground is doing you a disservice. The drivers left my delivery on the street next to my garbage cans after hurling it from the truck. I made it home to retrieve it just before the garbage man was due and would have taken it as part of the trash pickup. Online sellers, Sam's, Amazon, Wayfair - all of you - need to hear this: Fed Ex Ground is a terrible carrier.

We had this mattress less than 2 months and the foam warped and bulged and is sticking up inside the mattress. We are disappointed not only because we spent over $400 and the mattress lasted less than 2 months, but it would be entirely too difficult to return as it comes vacuum-packed in a bag/box and is quite heavy. Attaching pictures, although I'm not sure if you'll be able to see the warping. Buyer beware--this is a cheap item.

After reading the negative and positive reviews for this mattress, I decided to give it a shot because we were in desperate need of a replacement. This mattress is advertised as a medium-firm mattress, but it is NOT that whatsoever. This mattress is SOFT... so soft that your entire body will sink in if you weigh over 150lbs. If you’re into that, then it may work for you. But if you bought a medium-firm mattress because you prefer medium-firm mattresses, you will be highly disappointed. If you prefer firm mattresses and thought you might just settle for a “medium-firm”, then you may fall into a deep depression. Believe me before you waste your money like I did... this mattress is nowhere near medium firm, or even medium. Also, prepare to have your room smell like chemicals for several days. We off-gassed and decompressed this thing for an entire day outside and the smell is still giving me headaches. Here’s to hoping I can return this thing!

Supposed to be medium firm, but there is NOTHING firm about it! Sit on side and sink all the way down. At least 2 inches wider than normal king. Yes, we let it setup before use, but it only rose to 10 inches. Box said 12! Should be labeled extra squishy! I want my old mattress back! Totally disappointed with this purchase! Btw won't allow me to give zero stars!

King mattress purchased via pickup at local Sam's Club. First the box weight is about 80 pounds. The Sam's associate brought it out on a flat cart and didn't even attempt to load it in my truck. Never offered to help even as I stuggled to lift in the back of my truck. Got the mattress home and removed from box. Removed the plastic. I let it expand for 72 hours. It seem the cover is bigger than foam. When we put it on the bed the cover bunched up and was very loose.

Mattress is Comfortable & Supportive for the money. There is better mattresses for more money but this was definitely better than the traditional spring mattress it was going to replace. Motion transfer was better than the spring mattress, but have sleep on better in hotel rooms. I natural sleep hot & this was a hot mattress. My fiancé normally sleeps cold, but she was also hot temperature wise. Already ordered more expensive mattress than has better reviews for cooling & will be returning soon. If it sleep cooler would be keeping.
