Hybrid Comfort System - Combines independent pocket springs with responsive memory foam. The springs provide targeted support and reduce motion transfer (ideal for couples), while the foam conforms to your body curves for pressure relief. Offers a medium firm feel – supportive yet soft enough for side/back/stomach sleepers.
Sleek Black & Gray Design - Features a modern black top surface with stylish gray side panels. The stain-resistant, textured fabric looks sharp with any bedding and adds a premium touch to your bedroom.
Excellent Support & Breathability - The independent pocket springs adapt to your spine alignment (great for back pain). Airflow channels between springs and foam layers, plus a breathable side fabric, prevent heat buildup,keeps you cool all night.
Mattress in a Box, Easy Setup - Expertly compressed, rolled, and shipped in a manageable box. Simply unbox, unroll onto your bed frame (slatted base, box spring, or floor), and let it expand within 24‑48 hours. Zero fiberglas.
Suitable for Multiple Sleepers & Risk-Free Trial - Medium firmness satisfies most preferences – soft enough for side sleepers’ shoulders, firm enough for back/stomach sleepers’ lumbar support. Backed by a 100-night trial and 10-year limited warranty.
Safety Notice for Unpacking- It is imperative to meticulously adhere to the prescribed unpacking procedures to prevent the mattress from undergoing rapid expansion upon exposure to atmospheric conditions, which could potentially lead to forceful impact and consequent injuries.

Great For Price

Looks great feels great. Bought for our spare bedroom, so it really won’t get a ton of use. It is perfect for our needs.

Best sleep I have had in a while!!

Did recent weeks long sleep test on a similar bed at my daughter's. This bed is perfect and sleeps just like hers did!! The medium firm is exactly the firmness I was looking for. The mattress sleeps cool and I love the non-traditional black color! The package was shipped perfectly and slowly released its tension when inner plastic wrap was opened for an easy setup. Arrived on time. No flaws! I slept on it after 48hrs (it was ok). But it slept much better after the 72 hrs. I kept is uncovered in order for it to reach its full potential within the 72 hr time frame. There was a bit of an odor from it - I simply opened a window and shut the bedroom door just after opening and let it air out during the day. I was able to sleep in the same room that night. The sleep is perfect and my lower back pain is gone! A great price for a better night's sleep!!

Great if you prefer a bit firmer. 2” topper needed.

Nice. Inflated to 14” asap. Didn’t sleep on it asap however. I do like the height vs 12” medium with plush top. This does not have a plush top. I realize I miss that. This mattress is firmer due to lack of plush top. Suppose I can always put a topper on. No regrets, however. I do like the darker color for change up. I do recommend if you prefer a firmer top. Edit 8/14: perfect with a 2” topper!!

Great Mattress

Ordered this for my son at college and had it shipped directly to his house. He says it sleeps great and is very comfortable. Of course, Hawkins Woodshop was amazing on their delivery!

Great product for the price

I bought this for my 14 yr old grandson and he loves it. He was able to unbox it himself and set it up. He says it is so comfortable that he doesn't want to get out of bed. The price was very reasonable as well.
