Is this mattress hot to sleep on?

The Shiloh mattress is designed to be neutral in terms of sleep temperature. The foam is an “open cell” design to encourage airflow.

A few Amazon reviewers reported that the mattress was too hot. Others thought it was slightly warmer than other memory foam mattresses.

Will this mattress help my back pain?

Reviewers that suffer from back pain said that the firmness of the mattress really helped them. A few said it took a few days to get used to the new mattress.

How will our size affect the mattress comfort?

The Shiloh mattress is designed for the average to bigger body. Most reviewers stated that their bigger size was not a problem with this mattress.

One reviewer, however, said that the mattress creates a hammock effect around the larger person, and that the smaller person beside them was drawn into their space. Another person said that their partner could be doing cartwheels on the other side of the bed, and they would not notice.

What is the composition of this mattress?

The Sleep Innovations website states that the memory foam is produced in the United States. For all sizes except King and California King, Amazon notes that the overall product is “Made in USA or Imported.” A few reviewers were under the impression that the mattress was manufactured in China.

Layer Components

Sleep-Innovations-Shiloh-12The overall design is called DuoComfort and includes two layers.

The top layer is 2.5 inches of SureTemp Memory Foam. This foam is an open cell design that allows good airflow.

The lower layer is 9.5 inches of Support-Plus Foam. This type of foam is more rigid. It is designed to provide stability and support.

Fabric cover

The cover is a soft poly-cotton blend.

Do I need to buy a foundation or bed frame?

The purchase includes only the mattress. It works best with a box spring or platform foundation with good air circulation. It is not recommended for use on the floor or any flat surface. It is not designed for slatted bases, which will not be able to support this mattress

Is there a chemical smell from this mattress?

The instructions suggest giving the mattress 12 to 24 hours to air out. I could not find any complaints of a chemical smell after that period.

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

Sleep Innovations foam products are certified by CertiPur-US. They do not contain formaldehyde or any known toxins.

The mattress is treated with an anti-microbial blend to discourage mold and mildew.

How do I look after this mattress?

Sleep-Innovations-Shiloh-under-12There is no need to flip the Shiloh mattress, but an occasional rotating is recommended.

The supplied cover can be spot cleaned with a damp cloth dipped in a mild detergent and water. Using bleach will destroy the foam. Ensure the mattress is dry before replacing the bedding.

Some customers reported that they washed and replaced the zipper cover successfully. However, the warranty requires that the cover not be removed or laundered.

As the mattress ages, oxidisation may cause it to change color slightly. This is to be expected and does not affect the comfort or performance of the mattress.

How long does this mattress last?

The warranty is for 20 years. An Amazon customer said they had had this mattress for 10 years and would buy another one “in a heartbeat.”

Is there a Warranty?

Sleep-Innovations-Shiloh-WarrantyThe warranty undertakes that the cover and foam are free from defects in materials or workmanship. The warranty period of 20 years begins on the date of the original purchase. Only one replacement is allowed during the warranty period.

The warranty is voided if the cover is removed or laundered. The cover can only be maintained by spot cleaning. Amazon customers repeatedly recommended the use of a second waterproof mattress cover.

Shipping is free. This mattress does not currently ship internationally.

Is the mattress hard to unpack?

The mattress is vacuum-packed in plastic and then packed in a cardboard box. The box for the Queen size is 23x23x40 inches. It should fit in the back of a small car if the back seat is flat. Keep in mind that it is fairly heavy. See table below for weights. Detailed unpacking instructions are included. It is recommended that the mattress be unpacked within 72 hours of delivery.

  • Ensure you take the mattress to its final position before unpacking.
  • After the mattress is released from the plastic, it will start to expand immediately.
  • It will take up to 48 hours to completely expand.
  • You can sleep on it prior to this, but keep in mind that Sleep Innovations advises that it needs some airing.
  • The yellow zipped side should be on the bottom, and the contoured side on top.

The Sleep Innovations website indicates that if this is a winter purchase, you might want to wait for the mattress to reach room temperature before using it.

There were some reports that the center part of the mattress was bulging when unpacked. Those customers stated that the bulge disappeared after a couple of days.

Once the mattress is unpacked, it cannot be packed back into the shipping box. It should be moved or transported like any normal mattress.

Is there a trial period?

There is a 30-day trial period.

Customer Service

I noticed that none of the questions asked by Amazon customers were answered by identifiable Sleep Innovations staff.

On the Plus Side

• Good value for the price
• Sleep temperature is neutral
• Memory foam is made in the USA

Some Negatives

• There are no transportation handles on this mattress.
• Removing or laundering the mattress cover will void the warranty. Buying a waterproof mattress cover is recommended.
• Side sleepers may need to purchase a mattress topper to relieve pressure points.

Is this mattress right for you?

If you want a soft mattress, this is not the mattress for you. It is a firm mattress that adapts to your shape with a “cradling” effect.

Overall, Amazon customers are very satisfied with this mattress. The most frequent comment was that this mattress is good value for the price.
