Signature Sleep 12-inch Memory Foam Mattress Review

Dorel Industries, the maker of Signature Sleep, has been in business since 1987. The Signature Sleep 12-inch Memory Foam Mattress is designed to shape itself to your body, providing comfort as well as firm support.

How firm is this mattress?

This mattress is described as firm and solid by most of the Amazon reviewers. Over time, it will soften. Rotating the mattress from end to end is recommended to increase the life of the mattress.

Unlike other medium-firm to overly firm memory foam mattresses, there were a few reviewers who said this mattress was too soft.

What if I’m a stomach sleeper?

Stomach sleepers reported that it was comfortable after an appropriate break-in period, which ranged from days to weeks.

What if I’m a side sleeper?

Side sleepers said that it took a few days to a couple of weeks to get used to the firmness of the mattress. Some were not able to get used to the firmness and purchased a mattress topper.

Will my tossing and turning disturb my partner?

Signature Sleep 12-inch Memory Foam MattressThis mattress has isolating qualities, so you shouldn’t be woken by your partner’s movement. The Amazon reviewers state that this mattress is firm, and they do not feel movements by their partner. One person even said that a drinking glass on the bed did not move when he did.

The low number of reviewers who reported that this mattress is too soft said that they had a choice of rolling together or sleeping on the edge.

Is there support around the edges of the mattress?

Yes, you can put your shoes and socks on, but a couple of people said it was better to sit a bit back from the edge.

Is this mattress hot to sleep on?

The general consensus seems to be that it is not as hot as other memory foam mattresses. Some thought it was a bit too warm, and purchased a cool gel mattress topper.

Will this mattress help my back pain?

This mattress is designed to give balanced support so that no one section of your body is feeling pressure. Most Amazon reviewers said that the morning back pain that they experienced with other mattresses disappeared when they slept on this mattress.

How will our size affect the mattress comfort?

The mattress is very solid, and the self-confessed heavier reviewers said that this mattress supports them without a problem. Sleepers who are over 260 lbs may find that they sink too far into the mattress.

What is the composition of this mattress?

This mattress is manufactured in China. Dorel Industries is based in Canada.

Signature Sleep 12-inch Memory Foam MattressLayer Components

The top layer is 3.5 inches of visco-elastic memory foam for your comfort.

The lower layer is 8.5 inches of high-density poly foam to provide support.

The memory foam used in the Signature Sleep mattress is certified by Certipur-US. According to the product description shown on Amazon, this mattress contains 2% fiberglass.

Fabric cover

The cover is made from a soft knit fabric.


This mattress meets federal flammability standard 16 CFR 1633.

Do I need to buy a foundation or bed frame?

Signature Sleep 12-inch Memory Foam MattressThis mattress requires a good foundation or platform bed. A solid base is recommended, although some reviewers said that a slatted bed was fine as long as the slats were no more than 3 inches apart.

Some reviewers reported that their Signature Sleep mattress worked well on the floor. The bottom side would need to be aired out once a month to avoid build-up of moisture and mold.

Is there a chemical smell from this mattress?

There will be a smell when the mattress is unpacked due to being packed in plastic. Allow your mattress to air out when not in use for the first few days. It should take 7 days for the smell to disappear completely.

Are a lot of chemicals used in the manufacture of this mattress?

This mattress is manufactured without the use of PBDEs, mercury, lead or any heavy metals. TDCPP or TCEP are not used in the fire retardant and meets the flammability standard 16 CFR 1633. The manufacturing process reduces Volatile Organic Compounds being released, which improves indoor air quality.

How do I look after this mattress?

Vacuum your mattress regularly. Do not remove the fabric cover. You can spot clean your mattress with a damp cloth. Using detergent or a washing machine might void the warranty.

Using a waterproof mattress protector is recommended to keep your mattress in tip-top condition. Also, stains or other damage may void your warranty.

This is a one-sided mattress and should not be flipped. However, rotating it every couple of months will help to extend the wear.

This mattress is not meant to be rolled and is not designed to bend. Once it is unpacked, it needs to be treated like a coil spring mattress.

How long does this mattress last?

There is no life expectancy mentioned on the Signature Sleep website.

Based on Amazon reviews, this mattress is not designed to last any longer than about 5 years. For a number of reviewers, sagging and body indentations became noticeable within a couple of years. This may partially explain why the warranty is only for 1 year.

Is there a Warranty?

The main comment by Amazon reviewers is that even though the warranty is only 1 year, it does not concern them because they love the mattress.

The limited warranty is for 1 year and covers defects in materials and workmanship. If you need to place a warranty claim, you need to supply your proof of purchase and the law tag attached to your mattress. You also need to have purchased the mattress new from an authorized dealer.

You would need to pay freight charges for the mattress to be returned. One reviewer said that given the price of the mattress it would be cheaper to buy another than to ship it back.

The warranty covers body indentation of 1.5 inches and greater as well as wires that have come loose or are broken.
For the warranty to be honored, the mattress needs to be kept on an appropriate foundation or bed frame. It needs to be in good condition with no stains. Cleaning fluids and washing machine must not have been used.

The memory foam will naturally soften over time, but this will not affect the ability of the mattress to provide relief from pressure.
