The South Bay Essentials 6 Inch Firm Memory Foam Mattress is the versatile one in the range. Use it as a traditional mattress, drop it into most sofa-bed furniture, fit it to a trundle, or put it anywhere a full-height mattress simply will not work.

Cloudy Mattress is an authorized South Bay dealer, so every Essentials mattress comes with full manufacturer coverage, secure checkout, and verified buyer reviews. The low 6-inch profile is what makes this model useful where other mattresses are not, fitting bunk beds, daybeds, and tight clearances without overwhelming the frame or blocking a guard rail.

A one-inch layer of gel-infused memory foam sits at the surface, promoting breathability and drawing heat away rather than letting it build up beneath the sleeper. That cooling attribute is something low-profile foam mattresses usually go without, since the thin build leaves little room for it. A cooling cover works alongside the top layer to keep the sleeping surface comfortable night after night.

Beneath the comfort layer, two inches of Ridge Foam act as the transition, balancing the cushioning of the surface against the support underneath so the mattress never feels thin despite its profile.

A three-inch Ridge Base Foam layer reinforces the entire structure. This matters more in a 6-inch mattress than most, because a low-profile mattress gets folded, stored, and moved in ways a standard one never does. The base gives the Essentials the stability to hold its shape inside a sofa bed or trundle rather than breaking down at the fold line after a season.

The feel is firm throughout, which suits back and stomach sleepers, guest room use, and the sofa-bed and trundle applications this model is built around. It is a mattress designed to last years rather than a summer of occasional guests, and it ships roll-packed for easy delivery and simple maneuvering into whatever space it is headed for.

 

Low 6-Inch Profile

A slim 6-inch build fits sofa beds, trundles, bunk beds, and tight spaces where a full-height mattress will not work or would sit dangerously high against a guard rail.

Works Inside Sofa-Bed Furniture

Flexible enough to fold into most sofa-bed mechanisms while holding its shape, so it functions as real bedding rather than the thin pad most pull-outs come with.

Gel-Infused Memory Foam

A one-inch gel-infused memory foam surface promotes breathability and draws heat away from the body, a cooling feature low-profile foam mattresses typically go without.

Cooling Cover

The cover works together with the gel-infused top layer to keep the sleeping surface comfortable through the night rather than warming up under body heat.

Ridge Foam Transition

Two inches of Ridge Foam balance the comfort of the surface against the support beneath, so the mattress feels substantial despite its slim profile.

Ridge Base Foam Stability

Three inches of Ridge Base Foam reinforce the structure, giving the mattress the durability to hold its shape through repeated folding, storing, and moving.

Firm Supportive Feel

A firm feel throughout suits back and stomach sleepers and holds up well in guest rooms, trundles, and sofa beds where consistent support matters more than plushness.

Key Mattress Benefits

Essentials Firm Memory Foam 6 Inch Mattress by South Bay

4 Layers
Of Cooling
Comfort

The exterior cover is built to keep the sleeping surface cool, working in combination with the gel-infused foam directly beneath it. On a low-profile mattress, where there is less material to disperse heat, the cover does meaningful work in keeping the surface comfortable through the night.

The comfort layer is one inch of gel-infused memory foam that contours lightly to the body while the gel infusion promotes breathability and draws heat away rather than letting it collect. This is the cooling element that most 6-inch foam mattresses leave out entirely.

Two inches of Ridge Foam sit between the comfort surface and the base, balancing the give of the top layer against the firmness below. This transition is what keeps a 6-inch mattress from feeling thin, distributing weight across the build rather than letting the sleeper press straight through to the foundation.

The foundation is three inches of Ridge Base Foam, which reinforces the entire structure and gives the mattress its firm feel. Because a low-profile mattress is regularly folded into a sofa bed, slid into a trundle, or moved between rooms, this base layer carries more responsibility than a standard mattress foundation, holding the shape through repeated handling rather than collapsing at the fold line.

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

It is designed for it. The 6-inch profile works inside most sofa-bed furniture, folding into the mechanism while the 3-inch Ridge Base Foam holds the structure together through repeated folding and storing. Check your sofa bed's stated mattress dimensions against the size you need before ordering.

For a firm feel, yes. The build uses all six inches deliberately: gel-infused memory foam for surface comfort and cooling, Ridge Foam to carry the transition, and a substantial 3-inch base for support. It suits back and stomach sleepers, guest rooms, bunks, and trundles, though side sleepers who need deep shoulder and hip cushioning would be better served by a thicker plush model.

Thin foam mattresses often do, since there is less material to move heat through. The Essentials addresses that directly with a gel-infused memory foam surface that draws heat away and a cooling cover working alongside it, which is more cooling attention than most 6-inch mattresses receive.

Yes. The 6-inch profile is well suited to bunk beds, where a thick mattress raises the sleeping surface too close to the guard rail. This height keeps the rail doing its job while still providing a proper supportive sleep surface.

It ships roll-packed, compressed and boxed, which makes it straightforward to carry upstairs, through narrow doorways, or out to a guest room before unboxing and letting it expand.
