Fabric: Body: Acrylic (11 %) Filament Poly (11 %) Para Aramid Fiber (5 %) Polyester (20 %) Viscose (53 %) Care Instructions: Product Care, Mattresses: Rest easy with the fact that your Ashley-Sleep mattress doesn’t require much care and maintenance. For starters all Ashley- Sleep mattresses are designed to be no flip—now isn’t that a relief! How to care for your mattress: To help keep your Ashley-Sleep mattress clean a thin mattress protector is recommended so it breathes to allow airflow and heat dissipation. Ashley-Sleep does not recommend you use a quilted mattress pad as it will change the feel of the mattress you selected at the store. It may also trap heat that needs to escape. Don’t use dry cleaning fluid of any type on your mattress. These chemicals could damage some of the comfort and upholstery materials. Vacuuming is the only recommended cleaning method. If you must clean a stain use mild soap with cold water and apply lightly allowing the mattress time to fully air dry. Please remind the kids not to jump on their Ashley-Sleep mattress as doing so can break down the inner construction and materials.

  • This was a great mattress at an even better price
Size: Queen Style: 12"
I was in desperate need of a new Queen-sized mattress. My old one was purchased in Oct 2018 & had huge dips in it. The sides of the mattress were sloping off the sides bed, so I had to shove a pillow under the sides to raise it up. I was waking up achy & searched amazon. I've never bought a bed in a box for myself before & was nervous. I spent about 2 days searching & narrowed it down to this one & a name-brand I was unfamiliar with. I've tried mattresses out at Ashley store before, so felt more comfortable making this selection. It was on sale at the time & I liked the price. It arrived quickly, was packaged well, & inflated super quickly too. I didn't wait the recommended 24 hours, because i couldn't. My husband helped me get it on the bed around 11:30 am & I slept on it that night. It's much softer than I'd normally go for, but there's some support too. I'm mostly a side sleeper, and the first night was a rough night of getting used to it. It was comfortable, but I do find that we tend to feel pulled toward the center of the bed due to our weight. I woke in the middle of the night feeling warm & a little achy. However, I think that was just a period of adjustment. The 2nd night I slept well & the 3rd night I slept even better! It does have some bounce to it, so as one turns over, the other will feel it. I put a cooling mattress topper on it & that has helped tremendously! All in all, I'm surprisingly happy with this purchase & I hope the mattress holds up for some time. I'll come back later with an update, but so far I'm not seeing any dents in the mattress & I'm a large woman. I weigh 280 lbs. ... show more

  • Love Love Love! Did I Mention I Love It!
Size: Queen Style: 12"
After lots of research (3 months) I decided on this bed. I wanted something soft but supportive. I decided a hybrid was the best option for us. I stumbled across this originally on the Ashley website. They had it listed at $599 on sale at $249 for the 12 inch queen. This price made me ecstatic because I was planning on spending A LOT more. I budgeted $700 for a new mattress. I started looking at reveiws. Most were great, very few were not. I decided to check here on Amazon to see if prime was an option. It wasn't but it was cheaper and still offered free delivery. Ashley site said about 3 weeks to receive. I took a leap of faith and order here on Aug 31 (a friday) and was guaranteed delivery by the sept 14th. That Monday it shipped originally it was set to arrive Sept 7th but got delayed due to natural disaster (assuming California fires since it shipped from there and I am in Washington) and arrived Monday Sept 10th. This made me super happy! Be warned it is SUPER heavy like 100 lbs. I did move it and set it up myself because I am stubborn but you really should use two people. It was a huge struggle for me but I was determined to set up before the husband came home. Once opened it expanded immediately. The topper was fully expanded by bedtime 3 hours later. There was a strong chemical smell (normal for the memory foam) right when you unwrap it but was gone in a few minutes. OH MY once I laid down I was in heaven! The few reveiws saying this is hard as concrete are completely INSANE! It is very supportive but so plush and soft at the same time. Like sleeping on a marshmallow. Even my husband who doesn't care about anything luxury laid down and said it was amazing! (He snored all night long lol) It was the BEST night sleep ever. I am waking up with ZERO hip or shoulder pains. My arms arent going to sleep overnight. I dont need caffeine in the morning. Just like that this mattress has improve my life 1000%. My only complaint I don't want to get up in the morning because it is SOOOOOOOO comfy. We are buying 2 more for our kids ASAP. I am sure those super expensive $4000 are possibly better. But if you are like me and had a budget this is your mattress! Bonus I had money left for new bedding and pillows. Verdict I recommend this bed 1000 times over! ... show more

  • So Comfortable, We Bought Two!
Size: Queen Style: 12"
We bought two of the Signature Design by Ashley Queen Size Chime mattresses for our guest rooms, and they’ve been a total hit. One of them is in our guest bedroom that also doubles as a home office, and let’s just say—it’s become a favorite spot in the house. My husband regularly sneaks in to lie down because it’s that comfortable. He’s even talking about getting one for our own bedroom now! While we don’t sleep on them nightly, our guests consistently rave about how soft and supportive they are. Setup was a breeze—both mattresses expanded quickly and had no weird smells. They look great, feel luxurious, and offer amazing value for the price. Pros: Soft, cozy, and surprisingly supportive Easy to set up and ready to use quickly Guests love them—and so does my husband! Perfect for guest rooms or multi-use spaces Cons: May cause spontaneous nap sessions in your home office 😄 If you're looking for a mattress that impresses guests and tempts your spouse to relocate his naps, this is the one. We’re thrilled with both—and might be adding a third soon! ... show more
