Does The Casper Mattress Need A Box Spring
November 4, 2024 - Casper mattresses don’t need a box spring: Their foam and hybrid designs provide enough built-in support, making a box spring unnecessary. Alternative foundations work best: Platform beds, slatted foundations, bunkie boards, and adjustable bases offer ideal support for Casper mattresses.

Do I need a foundation?
A foundation (or box spring) provides support to the mattress so that it doesn't sag. Box springs are common when you have a bed frame that's just a metal frame that doesn't have support in it. If you have a solid or slatted foundation (slats only a couple of inches apart at most, I believe) then you don't need a box spring, unless the mattress company says you need it for your warranty. Basically, you need something- slats, a solid foundation on your bed frame, or a box spring so that the mattress has solid support throughout the whole thing so the mattress doesn't start to sag.

Need help with a foundation. Moving to a Casper but not sure what would be the best box spring/foundation.

This is another option:

Serves as your frame and box spring all in one, malouf also makes a fitted bed skirt for it too.

Before you pull the trigger on a Casper I would recommend checking out a couple local stores to see what they have for a 10" memory foam.

Do you need a foundation for a mattress?

Much like the foundation of your home, a mattress foundation provides critical support for the entire bed. To keep sagging at bay, you need a strong and leveled base for your new mattress. This is especially true for memory foam mattresses and innerspring mattresses, as they require adequate support to maintain their structure.

At Casper, our mattress foundations are designed to protect all mattresses from degradation, no matter the bed frame or material. For sleepers with no bed foundation or just an old box spring, it’s time for an upgrade to truly complement your mattress purchase.

What is the best foundation for a mattress?

In short, one that protects your mattress and improves your sleep. Mattress bases range from metal slats to solid platforms. At Casper, we believe the best mattress foundation is our wooden slat model. The closely-spaced beams evenly level your mattress, providing structure without sacrificing comfort. This bed base is great for all types of mattresses, including memory foam, innerspring, and hybrid mattresses, and provides greater support compared to a traditional box spring or foundation.

Answer: No, they are meant for platform frames. We own two Endy’s at our summer cottage, which are a rival but similar product. For one we bought an Endy brand frame which has corregated slats the mattress sits on. It’s great, very well made and easy to assemble, but we found it a little too low ...

r/Mattress on Reddit: Help with slats/foundation - Casper
June 8, 2022 -

I bought a Casper Original and my existing IKEA Hemnes bed.

Casper said to replace my box springs with slats (or their expensive foundation). I tried the inexpensive Luroy slats, And I feel like it’s higher/supportive in the middle where the mid beam is and it feels like it sags on either side.

I’m guessing it’s the slats, but I’m struggling on what’s the best cost effective solution

Flat slats ? Piece of plywood on top of the slats ? $400 Casper foundation Bunkie board on top of slats ?

Any suggestions?
