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:

  1. 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.
  2. Don’t use dry cleaning fluid of any type on your mattress. These chemicals could damage some of the comfort and upholstery materials.
  3. 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.
  4. Please remind the kids not to jump on their Ashley-Sleep mattress, as doing so can break down the inner construction and materials.

Best sleep I’ve ever had!
I’m really well pleased with my recent purchase from BeautyRest! For the past month I’ve had the best sleep I’ve ever had as an adult! The comfort of being able to get a well nights rest is a must for me. I had been looking online when I had a friend to recommend this brand to me. She said she has had a wonderful experience with BeautyRest mattresses for years. So I thought I’d give them a try too! I’m glad I did I couldn’t be more pleased. This company is great at offering the best sleep quality products for their customers. I like that they have a great warranty for their products and stand behind their brand all the way to satisfy their customers! If your looking for a new mattress upgrade I’d like to recommend this mattress to you for a better nights sleep! Weather it’s a quick nap or a full night sleep this mattress won’t disappoint! It’s wonderful!

Best money I've ever spent
I have had my bed for about a year now, so I feel I have a valid review. The day I went mattress hunting, I could barely walk into the store, I was in so much pain. I have been a nurse for 20 years working at the bedside with critically ill patient, and it has taken a toll on my back and hips. I tried every mattress in the store. The C-Class black ultra-plush pillowtop with adjustable base, in zero gravity immediately helped my back pain. 2 weeks later I hunted down the best deal and customer service near me and became a proud new owner. My back pain, is 85-90% improved. This mattress most likely saved me from a close call with neurosurgeon consult. In addition, the adjustable base helps my gastric reflux. Literary a game changer for me.

This is the one to buy!
I bought a harmony lux diamond split king but I did not like it. It was too soft. I ordered a Black C class King with the Cooling and Comfort upgrade, $3799. They picked up the old beds and delivered the new bed for free during the 100-night trial. No problems. They did what they said they would do. My wife and I love this bed. It is soft yet firm. When I first sat on it I thought it was way too firm, but after I slept on it, I woke up with no aches or pains at all. I do not know why some people are complaining, I almost did not buy the bed because of it. Just try it yourself. I hope to keep it for the full 10 years.

My Beautyrest Review
I purchased this mattress close to one month ago now. I really wanted to take some time before I wrote an honest review because often, mattresses lose their luster shortly after you bring them home, much like anything with a cushion effect.

My initial thoughts on this mattress were that this is ideal for myself in that my body temperature seems to rise throughout the night time. I'll constantly wake with sweat on my neck and chest and I'll find it difficult to fall back asleep. This occurs on nights where my Central air is set to 68° and with a fan blowing on me.

In finding a Beautyrest mattress, that essentially cools me down, I was flabbergasted to say the least. Exciting but at the same time I was curious as to how that would even work or if this was a gimmick of some sort.

Since sleeping on this mattress, I have not woken during the night feeling hot or sweaty in the slightest. Nor have I woken feeling cold.

When I hear the sound of my alarm, that's when I wake and I'm waking now feeling completely rested and refreshed.

I also suffer from lower back pain due to degenerative disc disease and nerve damage so my mattress selection had to be just the right amount of firm associated with the right amount of soft.

This mattress has been my best friend since the first night I slept on it.

The Best Mattress
I purchased this mattress a year ago, and I am so thrilled that I did. I got the best sleep that I’ve gotten in years. Due to the fact that I have lower back problems, I didn’t toss and turn all night like I usually do. It is so soft and comfortable. I love the color. It is so perfect in all ways. I guarantee you will get your moneys worth. The quality of it is great! I’m loving the design also. I recommend this to everyone, I promise you won’t be sorry. Gorgeous soft mattress, you will fall in love!

  • Scott Living by Restonic Chelsea 11" Hybrid Medium Twin Mattress
    $596.99 - $821.99
    Description

    The Scott Living 11" Hybrid mattress features a layer of gel-infused memory foam. Gel-infused memory foam is more resilient than traditional memory foam. While traditional memory foam can leave the sleeper immobile due to its slow reaction time, gel-infused memory foam allows the sleeper to move freely. As a result, it's suited to a variety of sleep positions, adding to its comfort and versatility. The exclusive 2Cool® technology helps regulate body temperature, creating a cool, comfortable sleep environment throughout the night. By gently and consistently moving heat away from your body, you’ll enjoy a night of restful, undisturbed sleep. The Support Q5 coil system incorporates individually wrapped coils to give a customized level of support as well as motion separation, while the Support Edge is a band of outer coils that have two coils wrapped together, to help avoid the feeling that you are rolling off the edge of the bed. This mattress features a layer of Super Soft Comfort Foam. Softer mattresses are generally better for those who sleep on their side, as they better cushion the shoulders and hips and better align the spine.
