About this item
Product details
Our foundation provides excellent support under any Casper Sleep 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 mattress. Our foundation's slats are positioned a perfect four inches apart for optimal support. Similar to a house, a mattress needs a foundation as a strong base to support it. The function of a foundation is to provide support for the mattress and ultimately extend the lifespan of the product. Additionally, raising the mattress allows us to get in and out of bed easier.
- Woven Exterior Upholstery-Foundation dimensions – 59.5" W x 74" L x 7.5" H-Hold weight – 750 lbs.
- Slats distance from each other – 4”-Ships in a compact box and can be easily assembled in minutes - without any tools
- Non-Woven Interior and -Slat Upholstery
- The Casper foundation is engineered to provide excellent support under your Casper mattress but can be used with other mattresses in place of a traditional box spring-Engineered with solid wood and rigorously tested for durability and proven to stand up to years of sleep. Slats are positioned a perfect four inches apart for optimal support
- Compatibility-works with any mattress. Requires a simple metal bed frame, slatted bed frame, or a platform (if you want extra height)
- The foundation should not be put directly on the floor
- 30-night trial

Super impressed
I recently purchased a Casper foundation and metal frame. The packaging was amazing - the foundation comes in four pieces held together in twos by four pegs. You remove the pegs, line up the four pieces and put the pegs back in the corners and you're done! I was in shock at the ease of assembly. It took 5 minutes. For something so simple you would think it might have structural issues, but it is the most sturdy bed frame I have ever owned. I recommend their foundation and metal frame combo to everyone I know!

this is for the Foundation
I have to say I was skeptical about buying this online thinking how good could it be or how hard will it be to assemble. I have to say 1st off the hardest part about this was getting it out of the box. After that it took about 10 minutes to assemble. I love how easy it assembles and how sturdy it is. I'll be buying another in the futures.
Review for the Foundation for a Casper Snow King
[This review was collected as part of a promotion.] Just received our foundation base recently and it is a cinch to put together and very sturdy. The mattress itself is pretty dense and heavy so it's reassuring to know that it is being supported well from underneath. All the sides have a nice fabric cover to them and the wooden slats are neatly woven into a fabric casing. Great touches. Thanks Casper!
