The firm mattress offers classic tailoring with fewer plush comfort layers at the sleep surface than our other models, so you will feel the support system more prominently when you lie down.

Size Name: Queen Vine Customer Review of Free Product ( What's this? )
The Serta Perfect Sleeper Stanberry Firm Mattress provides a restful sleep for those who require a firm mattress. And it does so for under a grand (for the queen size). I've tested the Stanberry Firm mattress for about a month now and have some thoughts for prospective mattress shoppers.

For starters, in order to benefit from the firm support of this mattress, you'll need some kind of stable box spring/foundation. The first day I had the mattress I temporarily put it directly on a bed frame. Moving it to a standard queen sized foundation made a noticeable difference in head-to-toe stability and firmness. I wouldn't bother buying the Stanberry unless you are putting it on a foundation.

Over the past 12 years I've slept on another spring-based Serta, a spring-foam combination Simmons, and recently, a mid-range Tempur-pedic. The Serta Stanberry is not the best mattress I've regularly used, however, it is an outstanding queen sized firm mattress for under a thousand. I personally think you have to spend at least $350 beyond the Stanberry to get a Beautyrest that is better. Of course, if you can afford three times the cost of the Stanberry, well, nothing will come close to a nice Tempur-pedic. So everything here is relative and personal preference.

The description states that the Stanberry has a foam top with some kind of cooling gel infused inside of it. Do not confuse this with a pillow-top style mattress. The gel-foam stuff is tucked into the top and sewn-in even with the edges of the mattress. Honestly, I don't feel the foam that much and I definitely do not feel some kind of magical "cooling gel." I find most cooling memory foam gels to be a gimmick, though (just because they dye memory foam blue doesn't make it "cooling").

Size Name: Queen Vine Customer Review of Free Product ( What's this? )
After 22 years of faithful service, my previous mattress (also a Serta) had seen it's day. During my adult life I have purchased only two brands of mattresses, Serta and Sealey. (depending on what was on sale) I have had very good luck from both brands and was thrilled to be given the chance to test and review this particular Serta Queen Sized 'Perfect Sleeper Stanberry Firm'.

Delivery was confirmed via phone call and yesterday I anxiously awaited the truck from ABF shipping company. The driver was running late and called me for a heads up. Upon arrival I was a bit surprised to see he was the only one unloading the mattress and doubly shocked to see him put it on his head and carry it up to my front door with no help from anyone else. Whatever they are paying this guy, it is not enough!

**Please see the "Comments Section" of this review for details regarding my delivery experience.

It is noteworthy to say this mattress weighs quite a bit less than my previous Serta, but that is most likely due to this one being a single sided model, whereas my older mattress was double sided and flippable. Heavy duty handles on both sides are nice, but pretty useless unless you are 7 feet tall as far as lifting and carrying the thing. Handles on the ends of the bed would make much more sense to me.

The outer finish is very nice and the level of craftsmanship is very high all around. Please see product images that I have uploaded. A very slight manufacturing odor was present, but nothing overpowering or untoward. If you are sensitive to chemical smells as much as I am, you can rest assured it is not a problem with this mattress at all. It just basically has the "new Mattress" smell to it.

Was worried about buying a mattress on line but couldn't resist the deal. The mattress was exactly what I was looking for to put in my kids bunkbeds. Definitely high quality construction. Amazon delivery was great! No issues whatsoever.

Size Name: Queen Vine Customer Review of Free Product ( What's this? )
Once upon a time, we needed a new mattress and I didn’t want to buy one. It’s time consuming, trying to please two people with preferences that rarely align and the thought of shopping for one with my husband was not a high priority. So imagine my surprise when we found this perfect mattress without any real effort. It’s firm and solidly made, with a nice layer of padding on the top. This means you cannot flip the mattress to reduce wear and tear, however. I’m not sure how long this mattress will last as a result but I’m optimistic. Or maybe, I’m just mostly hopeful because, seriously, this mattress is so perfectly comfortable that the very first night I slept on it, I honestly slept better than I had been. A week later, I was still sleeping better. My husband agrees; this is a great mattress. Very comfortable. We’re both sleeping better. How’s that for a recommendation? From where I’m resting, it doesn’t get much better.
