ABOUT CASPER
Casper was created to re-imagine sleep from the ground up, beginning with its obsessively engineered, outrageously comfortable mattress. All of Casper's sleep products are developed in-house by the company's award-winning R&D team.
Casper was recently named one of Fast Company's Most Innovative Companies in the World and its eponymous mattress was crowned one of TIME Magazine's Best Inventions.
FAQs
What is the 120-Night Trial?
We believe you should actually sleep on a product to decide if you like it. So we give you 120 nights to test out all Casper products in your own home. If you don't love it, we'll give you a full refund.
Why does the Casper need a foundation?
The foundation helps support the Casper while optimizing air flow to ensure a restful night's sleep.
Can I put the foundation on the floor?
We do not recommend putting the foundation directly on the floor as doing so can cause wear to the chambray cover.

Q: how much weight can a queen sized foundation hold?

Q: What is the reason that this foundation should not be placed on the floor or carpet? One of your answers said, "We don't recommend placing the foundation directly on the floor, even a carpeted one!"
submitted by MX - 3 years ago
A: Great question, placing your foundation directly on the floor may not allow for sufficient airflow. When airflow is restricted this can sometimes lead to mold and mildew growth which risks damaging the integrity of the foundation. That being said, placing your foundation directly on the floor will void your warranty.

Q: Hello, does this foundation allow to add individual legs direction to the base?
submitted by mga - 4 years ago
A: We do not suggest adding legs to your foundation. The foundation works much like a box spring and should be placed on a frame.
submitted byCasper Sleep Team - 4 years agoBrand expert
Q: If getting a hybrid is the foundation needed or can one use standard box spring?
submitted by RetinChs - 5 years ago
A: A foundation ensures that mattresses sleep like they should. Some older box springs or foundations don’t provide a solid surface, causing mattresses to sag from the breaks in support. A strong and level foundation helps mattresses to perform at their peak for a decade or more, no matter what kind of bed frame they sit on. Casper foundations and mattresses (including our hybrids) are the perfect pair. We spent over a year developing the Casper foundation, so its design has the same considerations as our mattresses. It comes in the classic Casper chambray, so it goes perfectly with the rest of the Casper products.

Q: If you have a king size bed frame with a wooden support in center, should you purchase two twin XL foundations
submitted by Sue - 6 years ago
A: We recommend purchasing the King Foundation! It should position itself perfectly on the bed frame and the sturdy construction of the King Foundation is the ideal setup for any Casper mattress.

Q: Hi, does the foundation fold up? This may be a dumb question as I know that is what your company is known for--but just making sure! We have a very tight space this needs to get into!
submitted by Tina - 6 years ago
A: Hello, Tina! That is absolutely not a dumb question considering that traditional boxsprings are such a pain to fit in tight spaces! Our foundation comes disassembled and packaged in a box that will fit through doorways and up tight staircases. Putting it together requires no tools, either. Plus, if you ever need to move it, you can easily disassemble it again. For reference, here are the foundation box dimensions and weights for each size: Twin: 70.5” x 17” x 10”, 57 lbs Twin XL: 75.5” x 17 “x 10”, 58 lbs Full: 70.5” x 17” x 10", 63 lbs Queen: 75.5” x 17" x 10”, 68 lbs King: 77” x 17” x 10”, 81 lbs Cal King: 79.5” x 17” x 10”, 80 lbs

I purchased this as part
I purchased this as part of the bundle package and was really disappointed by how unstable it is. The slats are sewn into a fabric that simply rolls out onto the frame, but they aren’t secured in any way. The edges that are meant to support the slats are very narrow, so if you sit on the side of the bed, the slats slip off and your mattress ends up partially unsupported. Overall, the design feels poorly thought out and not sturdy enough for everyday use.

It works. It’s nice that it comes apart for moving. It’s kind of heavy and is largely just wood covered with fabric. Raw, unsanded wood corners are threatening to poke out of the decorative fabric cover, which doesn’t thrill me.
