Can I just buy the mattress?

I have my eye on a Casper mattress. Already slept on one, I'm sold. I'm also looking to pair it with an IKEA bed frame like this. Is the slatted bed-frame enough support, of will I need to buy the $$$ foundation as well?

I have paired a twin sized Casper mattress, an IKEA frame and tried both the Luroy slatted base and the Espevar foundation. I've had no issues with either foundation setup. The bed is ostensibly for my child's room but I have fallen asleep on the bed so many times that I can certainly vouch for the comfort. We've had it for close to two years now.

Best answer: The Casper FAQ says:

We designed the Casper mattress to be versatile, so it can work with all standard foundations. As with all foam beds, you want as much direct support under the mattress as possible. A wooden slatted or platform bed offers the most support.

So that seems pretty official.

Best answer: I sleep on a Casper mattress on a Luröy slatted base and have for over a year. It works fine.

(Don't forget to get the Luröy when you get the bed frame; it's not included but it is required, so it's a common thing people forget to pick up. A friend of mine once said "Luröy is Swedish for 'guess who's going back to Ikea?'")

We had a name-brand latex foam mattress on an Ikea slatted base and the mattress developed depressions. We got a Leesa mattress to replace it, and it started having the same issue. I read somewhere on the green that there's enough space between the slats to permit a foam mattress to deform on top. I had some big pieces of 1/4" plywood, so I cut them to fit on top of the slats, and the depression problems have gone away. It doesn't seem plausible that the space between the slats would permit that much deformation, but I guess it does. So I'd say go ahead with the slatted base, but fit some kind of non-slatted board like 1/4" ply or doorskin on top of the slats and you should be golden.

We have a Tuft & Needle mattress - similar to your Casper one. I went to a local, trusted furniture store and bought for it a simple, slatted bedframe, with one small alteration: I asked them to add, I think, 4 more slats, because I wanted to make sure there were no gaps big enough to allow for mattress sagging. The store was happy to oblige - I think it cost $5 extra per slat. It was easy to assemble and supports the mattress - with us on it - very well.

I used a mattress on top of an IKEA slatted base for 8 years. I don't actually recommend stretching it that long, but comfort wise it was pretty decent even for the last couple. The mattress did develop depressions on the bottom, but they weren't anything you could feel laying on top.

The one thing I might recommend if you plan to use it for more than a few years is picking up an extra slatted base. At some point the ribbons connecting the flats came apart on mine and it was sort of a pain in the ass to fix them.

I've had a (fairly similar, possibly even less firm) Leesa on top of 2.5"-spaced slats for a little over 1.5 years. No sagging into the gaps at all.

It is pretty cheap and easy to put additional slats under the mattress if they are needed.

Rule of thumb for foam mattresses, IIRC, is that the slats should be no more than 2 inches apart.

We got a Casper mattress over the winter for a third-party bed frame with slats 2 5/8" wide, spaced 1 3/8" apart. No evidence of sagging yet (I just checked while writing this), not even dents in the foam. I'm not going to worry about it further.

And like under_petticoat_rule says, if the bedframe has slats too narrow or spaced too far apart and you're concerned about sagging, DIY a layer of plywood, which should set you back maybe $30 in materials. A box spring or foundation is strictly a nice-to-have rather than a necessity.

We have a Brooklyn Bedding mattress (so, basically, your Casper) on the exact same Ikea frame. No foundation and no problems here! We have the cheapest wood Ikea bed slats--sometimes they'd get bunched up so we zip-tied them to the frame and now it stays put. The drawers underneath the frame are super useful, BTW.
