## Description

Our foundation provides excellent support under any Casper mattress and can be assembled in minutes -- no tools required. It can also be quickly disassembled if you are moving or need to maneuver around tight corners. Older box Springs’ slats tend to be too far apart, leaving room for a mattresses. Our foundation’s slats are positioned a perfect four inches apart for optimal support. Engineered with solid wood, it has been rigorously tested for durability and proven to stand up to years of sleep.

Review: Great foundation for Casper Mattress. - I purchased the king size foundation for our new bed. This item is high quality, easy to assemble, and well designed.
Review: This is the one to buy! - If you are looking for a box foundation, this is the one to get! We searched and searched and read tons of reviews on all different types of box springs. After reading so many, we landed on this from Casper. We had purchased a memory foam mattress, and realized it needed just a bit more support than the mattress alone. The biggest difference between this box spring and the others is the material. We had read some reviews about metal box springs, and heard that they eventually would squeak. That is a dealbreaker for us. Casper foundation is made of a sturdy material and comes with the Casper reputation. It was incredibly simple to put together. Just like any square item, you will want to ensure that they are lined up well prior to inserting the pegs. No tools were required. However, we did use a hammer for ease of positioning. It wasn’t necessary though. The difference with this boxspring underneath the mattress is night and day. It was well worth the additional price, and just like purchasing my mattress, the money was well spent.

### ⭐⭐⭐⭐⭐ Solid and Quiiiet
*by E***. on August 27, 2022*

This is a solid box spring foundation and has a classy look almost a gray tweed type material, ive matched mine with quiet balance frame and a dream cloud 14in mattress all compliment each other perfectly i also added a headboard and it's all perfection but back to the box spring very sturdy and the assembly was so easy it shipped quickly and the sale price was an instant draw . It's quality , it's a good use of your money you won't feel taken. I'd highly recommend this one.
