Description

California King Firm Luxury - 14.75gIf you're building a King mattress, and want something more firm that won't crush under higher body weights, this is for you: A California King 14. 75g 8" QuadCoil base A California King sized QuadMini 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.

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 California King 14.75g - 8" QuadCoil base
  • A California King sized QuadMini
  • 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. This combination is the right starting point for 90% of our customers.  Finish your build with a nice natural latex layer.  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.

Clean Look, Super Comfortable – Instantly a Favorite
Size: 9.5, Color: White Leather
These sneakers are exactly what I was looking for—sleek, minimal, and incredibly comfortable right out of the box. The white leather looks sharp and pairs easily with everything from jeans to chinos, even dressed-down office wear. What surprised me most was the comfort. The sole is lightweight with just the right amount of cushioning, making them perfect for walking around all day. I’ve worn them on long city days and never felt sore or tired. They fit true to size (I’m a 9.5 and they’re spot on), and the quality feels premium. If you're after a versatile white sneaker that balances style and comfort, these are 100% worth it.

Not for all surfaces.
Size: 11.5 Wide, Color: Black Leather/Optic White
The sneakers look great and are comfortable on flat, smooth surfaces. Warning: The sole is very flexible and not well cushioned so a walk on rough or uneven surfaces can become uncomfortable quickly. Just understand the limitations.

Comfort Meets Coastal Style – A New Favorite Tee
Size: X-Large, Color: Dark Heather
The Costa Del Mar Costa Topwater T‑Shirt is everything you want in a casual, everyday shirt. The material is super soft and lightweight, making it perfect for warm weather or long days outdoors. It feels breathable and comfortable without being too thin. The fit is spot on—true to size with a relaxed feel that doesn’t look baggy. The design is clean and stylish, with that classic Costa vibe that’s perfect whether you’re out on the water or just hanging out. After multiple washes, it’s held up great—no shrinking, fading, or losing its shape. You can tell it’s made with quality materials that are built to last. If you’re looking for a comfortable, good-looking t-shirt that represents a laid-back coastal lifestyle, this one is a great pick. Definitely worth it!

Great shirt, runs a tad small
Size: X-Large, Color: Navy
Great looking shirt and good value for the money. Depending on your build you may want to order a size larger. I'm 6'4" and 207. I typically wear an XL and ordered an XL. It fits me but is a little snug there is not much room in the shoulders and sleeves or body for that matter. If I were back to my previous weight of 245 with a larger waist I would have to return it and get a XXL.
