Brentwood Home Sierra Mattress Review

Brentwood Home Sierra Mattress Review 2


The Sierra mattress from Brentwood home is the one of the best values for your money. In short, you get all the quality and craftsmanship of a company that owns it own factory and all the value of a direct to consumer mattress backed by a very generous 120 night trial period and 25 year warranty.

Overview of the Sierra Mattress

Below is a video that gives you a quick overview of the mattress. This mattress is on the softer end of the spectrum for Brentwood and the foam and gel foam do a phenomenal job with pressure relief. Below is a video of me with the Sierra mattress.

Construction of the Sierra Mattress

  • Medium / Soft Feel
  • Gel memory foam to help with temperature regulation
  • New Zealand wool liner wicks away moisture and is naturally antimicrobial for a cooler, fresher mattress.
  • 4-way stretch knit with a wider, cushion-quilt design.
  • Handmade in Los Angeles and certified free of unhealthy chemicals, including harmful fire retardants, phthalates, and heavy metals.
  • 25-year warranty and 120-Night Guarantee

How the Sierra Mattress Feels

This mattress is very well built. The sides are constructed of furniture grade upholstery to give the mattress a sophisticated look. It also has sewn handles on each side to make rotating and carrying the mattress much easier.

This mattress is a little on the softer side which is great for pressure relief. You can see below that the top of the mattress has a tufted look to it which creates little valleys for air to flow through keeping you cool at night. The knit belgian fabric cover also helps reduce motion transfer by moving in all directions to keep the mattress from pulling in any particular direction when sleeping.

Here’s a picture of the type of cover that Brentwood uses. The sides are stitched to the top and bottom of the mattress. This is important because most foam mattresses have covers that are zippered. Having a stitched cover gives the mattress a much neater look and makes you bed look great.

The Sierra mattress isolates motion very well as most memory foam mattresses do. However it can isolate motion and recover quickly which is a great feature for an all foam mattress.

This mattress has more hug than most of the online mattresses I have tested. That’s in part due to the unique cover and knitting that gives it a tufted feel and the fact that the top layers of foam are less dense creating a great sinking feeling that cradles you while you sleep. Unlike the ultra dense foam mattresses, this one will conform and recover quickly. People that wake up with sore shoulders or hips will appreciate how this mattress works.

My Sierra Mattress Recommendation

Brentwood home doesn’t cut any corners with the Sierra mattress. Even though it’s priced below $800 for a queen which is significantly less than most of the other competitors in the space. This is a great mattress for people that want the feeling on a high priced mattress without the high price tag. Most memory foam mattresses are very similar in how they are constructed. What differentiates them is where they are made. Foams poured in China for instance lack many of the controls in the United States which can lead to inconsistent feel across mattresses. Brentwood Home mattresses are made 100% in the USA.

Brentwood has been making mattresses for decades and it shows in the quality of their product. They are able to draw upon their experience to create mattresses that raise the bar in every price point and category. Their product line continues to expand with excellent pillows as well. I highly recommend people that purchase any new mattress to upgrade their pillow. I was fortunate enough to try out the Sierra with the Aliso Feathered Gel pillow which works perfectly with the Sierra.

If you are in the market for a sleep upgrade, you owe it to yourself to try a Brentwood Home mattress. The Sierra is a great way to get introduced to their products with no risk since you get a 120 night trial with free shipping and free returns.
