The South Bay Essentials 8 Inch Gel Memory Foam Mattress is a value-focused sleep solution engineered for restorative nights without compromise.

Cloudy Mattress is the authorized seller of this South Bay International Bedding product, so every purchase comes from a trusted retail source.

The feel sits firmly on the supportive side of the comfort spectrum, making it a confident, firm 8-inch memory foam mattress that works beautifully for back-leaning sleepers.

Because of this, it earns a place as one of the best 8-inch mattresses for back sleepers in the value tier.

Inside, the construction layers gel-infused viscoelastic foam over a transitional foam and a stable base, delivering balanced contouring with structured pushback.

Furthermore, the cooling gel foam mattress 8 inch design pulls heat away from the body while the breathable base foam maintains airflow.

This translates into real cooling comfort for hot sleepers throughout the night.

The medium-firm response also encourages targeted spinal alignment support and deep pressure point relief across the hips, shoulders, and lower back.

Additionally, the 8-inch profile height is adjustable base compatible, making it an excellent 8-inch mattress for adjustable base setups.

The mattress arrives via Mattress-in-a-Box delivery, is ready to ship in select sizes, and is backed by a 10-year limited warranty. Financing through Affirm is also available at checkout for added flexibility.

Key Mattress Benefits

Essentials Gel Infused Memory Foam Comfort Reactive Firm 8 inch Mattress By South Bay

4 Layers
Of Cooling
Comfort

This top comfort layer is the gel-infused viscoelastic foam that gives the mattress its cradling feel. The gel infusion is engineered to promote breathability, so the surface stays cooler than traditional memory foam.

This middle layer functions as pressure-relieving reactive foam, smoothly bridging the soft top and the firm base. As a result, sleepers get balanced contouring without sinking too deeply, which helps with targeted spinal alignment support.

This bottom layer reinforces the stability of the mattress and gives the overall build its supportive backbone. Furthermore, the channeled construction promotes airflow through the core, supporting the cooling system from below.

The exterior cover unzips for easy laundering and helps reduce allergens with regular washing. Its breathable surface complements the gel-infused viscoelastic foam below for a consistently cool feel.

Designed for deep comfort and better rest, so you wake up refreshed and ready for the day

This mattress is an all-foam build. It uses three distinct foam layers, including gel-infused memory foam on top, ridge foam in the middle, and Air Channel base foam at the bottom. It does not contain innerspring coils.

The mattress sits on the medium-firm side of the comfort scale and is rated for back and side sleepers. Its transitional ridge foam supports proper alignment; however, individuals with chronic or diagnosed back conditions should consult a medical professional before purchase.

A box spring is not required. The mattress can be placed on any continuously solid surface, an adjustable base, or slats spaced no more than two inches apart. Cloudy Mattress also offers an optional box spring with a metal foundation as an add-on at checkout.

The mattress may take up to 72 hours to fully recover its shape after unboxing. You can sleep on it right away, as body heat and movement help speed the expansion process along.

Yes, all foams in this mattress are CertiPUR-US certified. They are made without formaldehyde, phthalates, ozone depleters, heavy metals, PBDEs, or the listed Tris flame retardants, and they meet low-VOC standards for indoor air quality.
