Product Care


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.


iComfort BLUE 300 Mattress is rated 4.7 out of 5 by 215.
Rated 5 out of 5 by from Nice firm mattress I have an adjustable bed and previously had a plush mattress following spinal fusion surgery. I wanted a firm mattress to provide support. I have had restful sleep and my back certainly feels much better. I would recommend this mattress to anyone who has had back surgery.

Rated 5 out of 5 by from Perfect Bed! I previously owned an iComfort (Savannah model, I believe). My mattress was damaged during a move and we needed to replace our mattress. I choose the Blue 300 Firm iComfort. The bed is very comfortable and perfect for my needs. The price is very reasonable and I have never had issues with my previous iComfort.

Rated 5 out of 5 by from Extremely comfortable bed This mattress along with the motion series adjustable base is wonderful. We saved a lot of money purchasing the Serta over other brands. We get a great night’s rest with this bed!

Rated 5 out of 5 by from Love Love our new Blue Touch 300 Firm Mattress So glad we listened to our friends who purchased their Blue Touch 300 a year ago. We were looking for the perfect mattress and we found it. Our sleep has improved already after sleeping on it 2 weeks. Got the split adjustable base for it as well. This mattress conforms to your body and makes you feel like your sleeping on a cloud! Ray our salesman was awesome to work with! Love it!!

Rated 5 out of 5 by from So far it compares well to our old Tempurpedic We received this mattress a day ago. Our first night of sleep was more restful than on the 4-year old Tempur-Pedic which this mattress substituted. I do hope it lasts longer than the Tempur-Pedic, which started sagging with my body weight at 4 years, making my body hurt all over. I was waking up in the morning feeling like I just took a beating all night long.

Rated 5 out of 5 by from Well built and very comfortable. I replaced my 28 year old Tempur-Pedic bed with a iComfort BLUE 300 Queen Mattress Motion Essentials III Queen Adjustable Base. I suffered from a back injury back in 1998 and as the years went on I was getting less and less sleep due to other issues that popped up over the years. I layed on this mattress system and adjusted it and my back spasms immediately stopped when I found the sweet spot. I was instantly sold. I'm looking forward to nights asleep again like when I was younger.

Rated 5 out of 5 by from Insurance Broker My husband and I only had our iComfort Temp Touch Blue Touch 300 Firm mattress for less than a month and it has made a difference in a good night rest in quite some time. I spend many hours visiting a vast senior market of clients daily, and all I want each evening is a good night rest. Since we purchased this mattress, I have been able to rest comfortably each night and wake each morning without the back aches ready to head out to visit clients. I would recommend this icomfort Blue Touch 300 Firm Mattress to anyone with back aches. Thanks to the iComfort Temp Blue Touch Blue 300 Firm Mattress, I'm well rested and excited to meet with clients. This also give me an opportunity to talk to my clients about how they could also benefit from a well rested night by visiting Mattress Firm and trying out the mattress. Thanks Serta for helping my husband and I rest better each night.
