Review context: Ben purchased and tested a full-size Signature Sleep Memoir 12-inch mattress. His observations concern that original sample; listings and specifications may have changed.
Our verdict
The original Memoir 12-inch mattress offered a slow, contouring memory-foam feel at a budget price. In Ben’s test, it felt firmer after fully expanding and produced a gradual sink rather than a springy surface. It may appeal to shoppers seeking a simple foam mattress for a guest room or a tighter budget, provided they are comfortable with foam’s close hug and potential warmth.
Consider it if: you like a slow response and limited bounce. Consider a different style if: you prefer a buoyant surface, stronger airflow, or an easily removable cover.
Our original hands-on test
Ben bought a full-size mattress and found that it took longer than many boxed mattresses to reach its full shape. In his review, it appeared very soft immediately after opening but felt considerably firmer after about three days. The original instructions allowed up to 72 hours for expansion; always follow the instructions supplied with your own mattress.
In a 14-pound bowling-ball demonstration, the top layer showed a slow sink. Ben described the feel as initially firm before the foam gradually conformed. His motion demonstration suggested relatively little movement across the mattress, though individual sleepers and foundations can affect the experience.

Our original Signature Sleep mattress videos
These are Yawnder’s original videos of the product reviewed at the time. Current models may differ.
Original construction and setup
The model reviewed was advertised as two layers: four inches of memory foam over eight inches of support foam, with a non-removable knit cover. This describes the historic sample, not necessarily the construction of a current listing. The original listing said its foam was CertiPUR-US certified; verify certification for the exact product and manufacturer.
CertiPUR-US certification applies to qualifying foam and specific content and emissions criteria. It does not mean an entire mattress is free of all chemicals. Check the CertiPUR-US program for its current requirements.
Feel, temperature and sleep position
Memory foam’s slow contour can help spread pressure for some side sleepers. Ben found the sample firmer than the Zinus Green Tea mattress he compared it with and thought it more accommodating for stomach sleeping. This is one tester’s impression, not a guarantee: body weight and mattress support will change the result.
Close-conforming foam can feel warmer than a more open, springy surface. Ben noted reports of heat retention and the absence of a phase-change cooling layer in the sample. If you sleep warm, consider the room, protector and bedding alongside the mattress.
How it compares
| Type | Typical feel | Tradeoff |
|---|---|---|
| Original Memoir foam | Slow contour, little bounce | Can feel warmer or harder to move on |
| Responsive foam | Faster recovery, less hug | Pressure relief depends on its layers |
| Hybrid | Foam over coils, often more bounce | Feel, price and motion transfer vary |

Frequently asked questions
Did Yawnder test the mattress?
Yes. Ben purchased the original full-size model; the findings are specific to that sample.
How long did it take to expand?
The reviewed mattress reached its fuller shape after about three days. Follow the instructions for the model you receive.
Does it sleep cool?
Temperature is individual. The original foam sample could retain warmth, and we did not conduct a controlled comparison.
Is the old price or trial still available?
We have not verified either. Check the current seller’s listing and policy.
