For the past few years, me and my wife have been sleeping on the extra firm Queen JC Penny base and 3" Sensus Foam topper. We have liked this combination (it might have been a tad too soft) until recently, when the base and Sensus topper both seemed to have lost the support they had when new. We want to upgrade to a King bed anyways, so this a a perfect time to build a new bed.

I have been reading a lot of posts on this forum, and here is my current planned setup (which seems to change daily as I read more)

1. King 4" FBM Lux High Quality Foam Base layer

2. King 3" FBM HD High Quality Foam Middle Layer

3. King 2" Sensus topper from overstock.com Comfort Layer

4. King 1" FBM Medium - Talalay Latex Comfort Layer

I was originally going to go with just 3 inches of the Sensus on top, but I am thinking that the memory foam + latex combo would give me more flexibility. I am looking to build a medium-firm bed that is closer to the medium then firm side. I plan on putting this on an Ikea King bed frame with slats.

Has anyone used a combo of memory foam + latex? I am thinking that I could switch them around to get the feel that we like best. Would 1 inch of Latex be enough for this, or should I go with 2? Also, do I need the 4 inches of LUX on the bottom, or will 3 be enough? Since this will sit on slats, I was thiking the extra inches would add to the support.

Thanks a lot for your help!

hi ruff,

i like the combination of latex and memory foam...I have a similar setup to you, though i have only 3" of Lux (plus 3" of the HD36-HQ), and i've been tweaking the top layers each night. I liked the Sensus MF (only have 1" of it) at first, but just didn't like the 'sinking' feeling at night. Also felt hot sleeping on it.

Right now i have the 6" of base, with 3" of eggcrate (hd6 and supersoft) and 1" latex on top. I'm going to see how that feels tonight.

But i did have MF and latex as toppers, together, at one point, and liked it. I think the latex adds a little spring and buoyancy to the toppers, which i like.

2" is more than enough memory foam. In fact if you can get 2 x 1" layers instead that will give you more flexibility.

I am currently using 1.5" of soft latex on TOP of 1" of Venus memory foam as my topper, and I like that better than the other way around.
I have tried it with 2" of Sensus and that's a little too much memory foam for me, though my wife likes it.

Otherwise, your plan sounds okay.

Thanks for the helpful replies.

I also wanted to make sure if the Ikea slotted bases are good for foam. I was in a furniture store and the guy was telling me that the foam could go through the slats and that I would need a more solid base, but I have a feeling that what he was saying is just not true.

Also, do you think that the 4 inches of LUX is necessary at the bottom, or would 3 be enough?

Hi Ruff,

I'm going with a 6" LUX base and skipping the HD Medium Foam altogether because someone reported on this forum that theirs broke down.  My middle layer is going to be 3 inches of talalay latex medium ILD, and I also bought 1 more inch of it as well as 1 inch of the Soft for flexibility until I find a combo I like best.  My LUX has already arrived, and my other layers will be here today so I'll update my DIY thread with pics today or tomorrow as well as a report on how I slept.  Two others on this forum have successfully done this same combination so I decided to try it, all materials are from FBM (LUX from foamdistributing = same company).

Last, the bed frame... I think that Polyurathane (PU) foam or memory foam could go through the slats like the guy said... slats are more for talalay latex, not PU or memory bases.  I'm building a king size (two twin XL's) flat platform frame with two 38X80X3/4 pine sheets.  I just got the wood last night, with the 2X4's it came to around $80.  A friend suggested I look into a clip-on system so holding off until Friday to decide whether I should use wood screws or a clip-on system that is easy to break down (have to do some more research on this).

The thing with the Ikea base slats is that I believe a lot (if not most) Ikea mattresses are foam. We have an Ikea futton that has slats as the base and 3-4 inches of foam as the mattress. We are currently sleeping on this for now until I build the new bed. I am not sure what kind of foam Ikea uses in these, but it is VERY firm. Considering how cheap their futons are, I cannot imagine they are using latex foam.

I would be suprised if Ikea designed their mattresses out of foam and foam on a slat base would not be a good idea since all their beds have slatted bases.  I guess the other option is to just put some solid wood on the botton of the bed frame instead of using the slotted base.

I have used HD or HR foam on an IKEA slotted base. For whatever reason I did not like the IKEA base and quit using it. But for the time I used it, it was okay.
If you have any doubt, I would recommend buying a SUPER firm piece of PU foam (HR would be best) and putting that on the bottom of the whole thing.

IF the slats are the kind that are adjustable then you may not want to put anything to firm on the bottom. If they are not adjustable then it shouldn't be an issue. If your bottom core layer is at least 40ILD or so, it should not be an issue in any case. I think you could try it as is, then after a week, then a month, etc. check to see if it's pushing deeply into the bottom. If it is, get a high ILD foam piece to put on the bottom. 1/2" should be enough.

I was doing some searching today and came across this mattress:

http://www.samsclub.com/shopping/navigate.do?dest=5&item=407909&pCatg=8375#reviews

For the $$, it would cost the same as a DIY, and it would be a little thicker (always a plus if not using a box spring under a mattress to get some more height). And samsclub supposedly has a warranty where you can return anything at any time, so that would also be a plus. The mattress has great reviews, but the specs do not specify what kind of foam is uses.

Do you guys think that it is better to buy an unknown mattress brand with good reviews and infinite warranty, or is it better to do a DIY bed where you know what the materials are, but not knowing what the results will be and with no real warranty on the DIY foam? Tough call...

Well, you can not beat the price. But I would be concerned since it is made in China, and they do not say what it is that you are buying for sure. No info on what the layers really are. But since it is so cheap, and they have a "take it back policy" it might be worth a try.

I'd probably write them and ask them what types and ILD's the foams are. What the heck is "cool foam"? That's the top 1".
The next 2" is memory foam... What lb. density?
Then 3" of "pressure relief" foam. What the heck is that?

If the 3rd layer of pressure relief foam is too soft, then that's going to be too much soft foam...

But the ratings are high on the several reviews it has, so maybe it's worth a try. As long as it has a 100% refund, why not try it?

If you do, let us know.

Overnightmattress.com has similar priced foam mattresses and a 120 night sleep trial with full refund. You might want to look at their's... (no I don't work for them)

Do you guys think it would be better to put the 1 inch of FMB Latex that is Soft - 20 ILD, or the Medium 32 ILD, under my 2 inches of the Sensus memory foam?
