    • Great for the price
Size: Queen Style: 12 Inch
For the price this is an incredible bed. It’s not the best you’ll ever have but it gets the job done. Medium firm and comfortable. The sides do compress a bit too much when you sit on the edge to put in socks but $200 is $200. I sleep great on it. Got the 12 inch queen

    • Great quality
Size: Full Style: 10 Inch
This mattress has been great quality! We use it as our guest bedroom mattress and it is well liked. The 10 inch is the perfect thickness and size mattress for what we need. It is very supportive and has great functionality for exactly what we need it for. I feel like it was GREAT value for our money. The mattress had to air ip once opened but that wasn’t a big deal at all and once we wait the recommended time. No smell at all. ... show more

    • Nice for the price
Size: Queen Style: 12 Inch
Comes in a box, makes moving a mattress easier. It filled out over night. Bought 3 for my guests rooms. No complains from the people using them. Don’t let the idea of “ in a box “ it can’t be good. BUT these are good and comfortable.

I recently bought the queen-size bed, and I couldn't be happier with it. From the moment it was set up, I noticed the sturdy frame and high-quality materials that make this bed feel premium. The design is both stylish and versatile, fitting perfectly into my bedroom decor. The mattress offers just the right balance of comfort and support, making it ideal for both back and side sleepers. ... show more
Reviewed in the United States on October 31, 2024 by I've been using these non-stick pots and pans for a few weeks, and I'm impressed! They heat evenly, and food slides right off with minimal oil, making cooking and cleanup a breeze. The durable coating hasn’t scratched, even with regular use. Handles stay cool, and they’re lightweight, making them easy to maneuver. So far, they’ve held up well, even after multiple washes. Highly recommend for anyone looking to upgrade their kitchen essentials!
    • Good. but a warning..
Size: Queen Style: 10 Inch Medium
I'm a average weight guy. So when my $600 mattress got a depression in it. You can imagine my emotional state. It was directly in the middle of the mattress. So turning it: hole. Flipping it: hole. I should say by depression I mean what felt like a gaping hole. My legs felt like they were touching the box spring. So obviously no good rest for me. I ordered this mattress as a stop gap solution. I no longer have the disposable income to simply go out and buy a $600 mattress on a whim. This was cheap and free overnight prime delivery. I must say that I am very impressed. The feel and quality of this mattress is extremely good. Very comfortable. It even came with a little cutting tool to slice through the 3ft thick amount of plastic they had it shrink wrapped in. Nothing like that was included with my $600 model. Yes I originally bought this as a temporary replacement. But as of right now I see no need to get rid of it or spend more money on another mattress. I am quite happy with this one. Now for the warning. The description says the firmness is medium. (The same as my old mattress.) It is not. At least not a medium like a mattress that I've ever had. It's not uncomfortable. But on a candy scale from marshmallow to jawbreaker. This mattress is more circus peanut and less caramel chew. So if you absolutely need something firm, skip this one. If you are okay sinking a little further into your mattress (but still with support). You can't really go wrong with this one. ... show more

    • It works
Size: Queen Style: 10 Inch Medium
You get what you pay for. The box was heavy, but it unpacked easy enough. I let it air and rise for about 3 days. I didn’t notice any smell. I will say it’s more soft than semi-firm. Not cloud soft, but a reasonable amount of give. I tend to like softer beds and it works for me. It doesn’t provide support on the edges so if you are looking to sit on the edge of the bed or sleep near the edge, it will roll you right off. But for the price, it gives a decent night sleep. For me it’s a temporary need for a couple months, so it would also work fine for a guest room. If you are looking for a good, every night, multi-year mattress, I would recommend spending a bit more, but if its for occasional use, this works fine. ... show more
