If you're building a King mattress, and want something more firm that won't crush under higher body weights, this is for you:

  • A split king 14.75g - 8" QuadCoil base (cheaper to ship, easier for you to handle)
  • A king sized QuadMini (eliminating concerns of a seam/gap from a split king)
  • Our premium zippered stretch cover designed from the bottom up for DIY builds. 

The 3" QuadMini is an upgrade found in premium commercial mattresses, providing more movement isolation and responsiveness than using latex or foam for your transition layer. 

Our goal in building this bundle for you was to take some of the guess work out of the DIY process. We've partnered with Sleep On Latex to offer their latex through our site for your convenience. If you order the latex at the same time as the rest of your bundle, the return window on the latex will be 30 days from the day your final bundle item ships. 

Pick a cover height that will fit the 11" of total coils in this bundle, plus however much latex you want to add. If in doubt, go one inch bigger than you need. The most popular option is 15".  We offer an 11" cover because some people choose to put just the coils in one cover, then the foam/latex layers in a separate cover. 

The discount on the QuadMini is built into the bundle price, plus an additional discount for buying the bundle together.

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!

So will not write down your foot
Size: Medium, Color: (001) Black / Black / Castlerock
I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.

Comfy and Stay Put
Size: Medium, Color: (002) Black / Black / Halo Gray
These socks are honestly great. They’re super thin and light, so once you have them on, you kind of forget they’re even there. No bulky feeling in your shoes at all. The best part is they actually stay on. I hate no-show socks that slide down after five minutes, and these don’t do that. The little grip on the heel really works, so you’re not constantly adjusting them all day. They’re breathable too, which is nice if your feet run warm. They dry fast and don’t get that gross sweaty feeling. And there’s no annoying seam on the toe, so nothing rubs or feels uncomfortable. Basically, they’re just comfy, stay put, and don’t cause problems — which is all I want from socks.
