Our verdict
The Acesleep foam mattress I tested had a noticeably cool-to-the-touch cover, a softer feel and a moderate foam hug. It conformed quickly without giving me the deeply trapped sensation of some memory-foam beds. I thought it was most appealing to side and back sleepers; stomach sleepers who prefer a firmer surface might find it too soft.
Review context: My observations and photographs are from the original 2018 mattress. For up-to-date alternatives, see our best cooling mattresses guide. The brand’s product page lists a cooling foam mattress, but confirm the current construction, stock and seller terms before assuming it matches the sample I tested.
Original mattress at a glance
| What we checked | Original 2018 Acesleep mattress |
|---|---|
| Construction | All-foam with a cooling-feel cover and multiple foam layers; not the same as a pocket-coil hybrid. |
| Feel in my test | Softer, contouring foam with a moderate hug. |
| Movement | Original demonstration illustrates movement; it is not a standardized motion-isolation score. |
| Cooling evidence | Cover felt cool on contact; no overnight temperature measurement was recorded. |
| Current availability | Verify today's model and retailer terms rather than assuming they match the 2018 mattress. |
Who should consider this feel
- Side sleepers: the softer surface and gradual transition between layers provided a contouring feel in my test.
- Back sleepers who like foam: the mattress offered noticeable cushioning without an extremely deep cradle for me.
- Stomach sleepers: a firmer bed may be a better starting point if this softer feel allows too much hip sink.
- Couples: an all-foam design can dampen movement, though the amount you notice depends on the sleepers and bed setup.
Delivery and setup
The mattress arrived compressed in a bag. I noted that it continued to take shape after opening, and suggested allowing time to experience its full feel. Follow the seller’s present unpacking instructions for any mattress you buy.
Original foam construction
The original manufacturer description listed a cooling cover above 2.5 inches of open-cell memory foam, 2 inches of bamboo memory foam, 1.5 inches of gel-infused memory foam and a 6-inch support core. The original description also made cooling and antibacterial claims that I did not independently test.
When I pressed on the top through the cover, I could feel air moving through it. That is an observation from the sample, not proof of a specific temperature reduction overnight.
My feel and sinkage test
The surface felt cool when I first touched it. I also found a medium amount of “hug”: enough contour to feel cushioned, without feeling stuck. I could not feel a harsh transition from one layer to the next while lying on the bed.
I used a slow-motion ball drop to illustrate movement in the original video. It is a practical visual test, not a laboratory measurement, and does not guarantee a partner will feel no movement.

Price, trial and shopping considerations
The original review included a 2018 price and a 120-day trial. Those terms may have changed and can differ by seller. Check the final price, return and pickup fees, foundation requirements and warranty for the exact product you order.
A cool-to-the-touch cover can feel pleasant at first contact, but it does not guarantee a particular overnight temperature. Bedding, the room and individual preferences all matter.
Frequently asked questions
Was the tested mattress soft or firm?
I found it on the softer side, with a moderate amount of contouring.
Is Acesleep a hybrid?
The sample in this review was an all-foam mattress; verify the current model before buying.
Will it feel cool all night?
The cover felt cool on contact in my test; I did not measure overnight temperature.
Bottom line
The original Acesleep was most compelling to me for its softer contouring foam and cool initial cover feel. The photographs and video document that historical model, not a test of the current listing. Compare the construction and return terms for the exact mattress before ordering.
