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.

What is the cheapest and best queen foundation I can buy?
The least expensive decent-quality foundation that has less than 3-in spacing (required for some mattresses) that I know of is from U.S. Boxspring: https://usboxspring.com/product/natural-wood-foundation/ If you want to go with a slatted bed frame instead, the least expensive decent quality bed frame with less than 3-in spacing that I know of is from Room Doctor: http://roomdoctor.com/shop/platform-beds/plateau-platform-bed/ Note that you need to call to order so that you can request the extra slat option (for additional fee) to get the spacing to less than 3-in.

Bought a Casper mattress, need bed frame recs.
If you want to stay on a budget you could get a platform bed frame from KD frames . They have proper slat spacing to support your mattress without the need for a separate foundation. If you do go with a frame and foundation combo just make sure the foundation you get is properly supportive with the slats spaced 3" or less apart. The term box spring is used to mean just about anything these days, but you wouldnt want to use an actual box spring as they are really a thing of the past. Modern mattresses need a solid foundation whether its a foam mattress or pocketed coils. More on reddit.com

How do you set up a Casper mattress?
According to Casper, you should let the mattress unroll in its plastic casing once you take it out of the box. A mattress will be ready to sleep on within minutes, but it may take up to 72 hours to expand to its true dimensions. (Note that it may take your body a month or so to adjust to a new mattress.) Casper mattresses are designed to work on a firm, solid surface. Having the correct support ensures the performance and longevity of memory-foam mattresses. With slatted frames, Casper recommends using flat wooden bed slats (not bowed), with slats no more than 4 inches apart. Casper offers a v

How long does a Casper mattress last?
Theoretically, you can expect any new mattress, including a Casper, to last about 10 years—the same length as Casper’s limited warranty. (This is pretty standard among bed-in-a-box companies.) Here are a few things you can do to increase the odds that your mattress will last that long or potentially even longer: Rotate the mattress at least every six months. Use a mattress protector to keep bedbugs and dust mites at bay. Make sure you have the right bed frame to support the mattress’s weight and keep it from sagging. (This also allows the mattress to “breathe,” thereby preventing mold and mil

Do Casper mattresses have fiberglass?
None of Casper’s mattresses contain fiberglass—a component that’s commonly used as a fire barrier in all-foam or hybrid mattresses. In recent years, mattress owners have raised concerns about the potential health risks from airborne fiberglass exposure. Remember, however, that exposure shouldn’t be a problem unless the mattress cover is damaged or removed. Therefore, we recommend that you never remove the manufacturer’s mattress cover; we also recommend that you invest in a mattress protector to keep your mattress clean.

r/Mattress on Reddit: Help with slats/foundation - Casper
June 7, 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?
