    • Luxury comfort with a budget price tag!
Size: King Style: 12"
For those who suffer from back problems and need good support while sleeping this is the best bang for your buck! Originally purchased in 2019 for a new home because of the price point, I have since fallen in love with this mattress. It’s firmer than most but that doesn’t take away from its comfortability. You’ll sleep through the night and wake up without back pain or aches. All king size sheets fit perfectly and snug to mattress. The 12 inch thick foam will leave you feeling elevated and fill in any bed frames. There is zero noise produced and it took less than 4 hours to fully expand. 10/10 would buy again! ... show more

    • Comfort for Every Body: A Heavyweight's Review of the Signature Design by Ashley Queen Size Chime
Size: Queen Style: 12"
I recently purchased the Signature Design by Ashley Queen Size Chime 12 Inch Medium Firm Memory Foam Mattress with Green Tea & Charcoal Gel, and I couldn't be happier with my decision. This mattress has exceeded my expectations in several key areas. First and foremost, the comfort level is outstanding. The medium firm support strikes a perfect balance, offering just the right amount of firmness without sacrificing comfort. The memory foam conforms to my body, providing excellent support and relieving pressure points. This has significantly improved the quality of my sleep, and I wake up feeling refreshed and pain-free. Initially, I was concerned about purchasing a boxed mattress online without trying it in person at a store. However, this mattress is comparable to a plush firm mattress available at local mattress stores, and my concerns were quickly put to rest once I experienced the comfort firsthand. One of the standout features of this mattress is the infusion of green tea and charcoal gel. These elements not only help with odor control but also maintain a fresh and cool sleeping environment. I've noticed a marked difference in temperature regulation compared to my previous mattress, and it stays comfortably cool throughout the night. The quality of construction is also impressive. The mattress feels durable and well-made, with high-quality materials that are evident from the first touch. It arrived well-packaged and was easy to set up. After allowing it to expand fully, it reached its full 12-inch height and retained its shape beautifully. Additionally, I was pleased to find that the mattress didn't have any off-gassing smell while it was expanding. It's worth noting that the delivery of the mattress was handled by a third-party delivery company. While the delivery was smooth, the boxed mattress is quite heavy and cumbersome to move with just one person. I highly recommend having two people to move it around the house and help with the setup. This will make the process much easier and more manageable. During the expansion process, I observed that the mattress sections on the outside of the roll expanded within an hour, while the section in the middle of the roll took about two days to fully expand. Due to this, I placed the middle rolled section by the footboard to allow additional expansion over time while still being able to use the mattress after 48 hours. As someone who weighs over 300 pounds, I find this mattress to be very comfortable and supportive. It provides excellent stability and does not sag, ensuring a restful night's sleep. What's more, it's extremely comfortable during side sleeping, providing the perfect level of cushioning and support. Overall, the Signature Design by Ashley Chime 12 Inch Memory Foam Mattress is a fantastic investment for anyone looking for a comfortable, supportive, and high-quality mattress. The added benefits of green tea and charcoal gel make it stand out in the crowded market of memory foam mattresses. I highly recommend it to anyone in search of a better night's sleep. ... show more

Great mattress. Leaving this review after purchasing this mattress in 2020 I am having no issues with sinking. The mattress is still firm and comfortable.

    • Great deal for the price
Size: Queen Style: 12"
For the money this seems to be a great mattress. I ordered 2 of these on the Black Friday sale. It pretty much takes 2 people to open it up and is quiet weighty. It's firm but comfortable. My husband likes a firm mattress and I like a little softer mattress ( because of issues with my rt hip...I need a softer mattress) and this one satiesfies both of us. We are both resting well on it and don't bother one another when getting up during the night. We neither one roll to the middle anymore. I wake up slightly sore but it attributed to having scoliosis and this mattress definitely has full body support with no sinking...so my body doesn't like being held in proper place. We are both waking up well rested and refreshed. We both have had serious neck and back issues so this is working great so far for us. I would prefer a little softer but its a personal preference and I'm adjusting...it's still soft enough that I sleep comfortably. Downside for us was that it isn't flipable because of zip liner and no cushioning on bottom side. We plan on rotating every couple of weeks and will see if it retains its shape and durability. I will try to remember to update again in a few months but overall the good outweighs the negative for us. ... show more
