More Information

The 12-Inch Medium-Firm Mattress In a Box allows users to sleep comfortably in a neutral position, which places less stress on muscles and reduces pressure points and body aches. Wake up refreshed after a good night's sleep on this mattress, which features high-quality interior construction that includes both pocket spring coils and fire-retardant foam. The individually wrapped springs act independently of each other, so they don't transfer motion across the mattress. This minimizes sleep interruptions and contributes to a better quality of rest. The pocket springs also allow air to flow through the mattress, which creates a cooler sleeping surface. This body-conforming mattress cradles the user in comfort, and its high-density foam construction provides extra cushioning to benefit the back, neck, and shoulders.

The 12-Inch Medium-Firm Mattress In a Box delivers a convenient online shopping experience along with a good night's sleep. When unwrapped from the plastic, the mattress will return to its original shape in 2 to 5 days. The convenient integrated handles make it easy to move, and it does require a foundation or box spring with the use of a standard frame. The twin-size mattress is also compatible with trundle beds and platform beds. It is designed not only for comfort but for durability. The top-quality construction found in the comfortable 12-inch foam and pocket spring mattress ensures its long-term value.

What Customers Are Saying:

"I've had this mattress for 2 weeks before I wrote this review to ensure my review was accurate. If you like medium-firm mattresses, this mattress is perfect for you. I added my memory foam topper to it and now it feels like I sleep on a soft, bouncy cloud. Overall this is a fantastic budget mattress, and I have not experienced a single issue with it so far. - Chelsea R."

"I'm a larger woman and was worried about buying a mattress before trying it. This is the first mattress I have purchased myself and this was definitely the right decision. It has been a month and I have had no issues. I love it! - Cassondra P."

"Buy this mattress! I am a very picky shopper and I went through all the reviews and after a lot of debate, I purchased it. It has been fantastic. I have allergies but this mattress has proven to not be an issue. Buy this mattress instead of a big box mattress, it's so much easier to deal with. - Tonya L."


FAQ For Mattress in a Box: Flash Furniture 12-Inch Medium-Firm Spring (Twin, Full, Queen, King)

? Have a question about this product? Click here to ask us!
Can I use this mattress as soon as I open it?
Answer: You can technically use this mattress when you open it, but it is highly recommended to let it sit for 2-5 days in order for it to regain its original shape.
Is there formaldehyde in the mattress?
Answer: There is no formaldehyde in this mattress.
I need a king-size mattress, would it be reasonable to get two twin mattresses so that I don't wind up with a soft spot in the middle of the king mattress?
Answer: This would not make a difference. Although it is a good idea, the mattress in king size is phenomenal and will not form a soft spot in the middle.
