Sleepys Memory Foam Mattresses

You might remember the Sleepys name as a nationwide chain of mattress stores. Mattress Firm acquired the Sleepys chain back in 2016, and now Sleepys has become a brand of mattresses sold at Mattress Firm.

The three mattresses in the Sleepys Memory Foam Collection--called the Snug, the Doze, and the Curve--are all-foam mattresses, with a comfort layer of charcoal-infused gel memory foam. Under that is a layer of convoluted (egg crate) gel foam, then a block of support foam. The three mattresses include different amounts of these foams, but all share the same three-layer construction.

The main comfort foam includes two features intended to help keep you cool. The foam is infused with both gel and charcoal, both higher density materials that are known conductors of heat. Their inclusion here is meant to help channel heat from your body.

Another cooling feature is a passive one. The layer of gel foam under the memory foam is convoluted; you might recognize it as egg-crate foam, with deep grooves carved into the foam. That means this foam has more air flow than a standard block of solid foam. Air flow, of course, can also help keep you from overheating.

A note on the memory foam: This is relatively quick-responding foam, which not much of that slow, melting-into-the-bed sensation you typically associate with memory foam. Rather, this foam springs back fairly quickly after you get off the bed. If you are concerned about feeling like you are sinking into quicksand, you won't get that feeling on these Sleepys mattresses.

In addition to the same overall construction, the three mattresses share a soft, stretchy cover that feels very breathable.

Prices for the mattresses start at about $400 (queen size).

Sleepys Snug Medium

The base model in the Sleepys Memory Foam collection is the Snug. It's an 8" tall mattress made with 2" of the charcoal-and-gel memory foam, then 2" of the convoluted gel foam, and a 4" solid block of support foam.

Sleepys calls this a Medium, but we think it's firmer than that on our scale. We'd call it a Medium Firm, and it's the firmest mattress of the three in the collection.

It also has quite shallow cushioning. Put another way, that means you feel more like you are floating on top of the mattress than sinking into it.

The mattress includes the same soft, stretchy cover shared by other mattresses in the Sleepys Memory Foam collection.

Sleepys Snug 10" Medium

Sleepys Doze Medium

The Doze is a 10" mattress with the same three-layer construction as the Snug, but with more foam in each layer. You get 2.5" of the charcoal-and-gel memory foam, plus 2.5" of the convoluted foam, and a 5" block of support foam.

Sleepys calls this a Medium mattress, but we found it to be a lot softer than the Snug, which they also call a Medium. On our scale, we would call the Doze a Medium Soft, and it's the softest of the three mattresses.

It also has more cushioning and conformance than the Snug, but no more than average compared to most mattresses. You still get more of a floating-on-top feeling rather than one of sinking in deeply to the mattress.

Sleepys Curve Plush

The next mattress in the collection, the Curve Plush, is a 12" mattress with 3" of the gel-and-charcoal memory foam, plus 3" of the convoluted foam, and a 6" block of support foam.

While Sleepys calls this a Plush, we found it to be more of a Medium in terms of softness. You do, however, get a lot more cushioning and conformance compared to the other two mattresses, so you do sink in more deeply, getting more of a hugged or cradled sensation.
