Description

California King Medium-Firm Luxury - 15.5gIf you're building a California King mattress, this is the most popular combination: A California King 15. 5g 8" QuadCoil base, a California King sized QuadMini, and 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

If you're building a California King mattress, this is the most popular combination: A California King 15.5g - 8" QuadCoil base, a California King sized QuadMini, and 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.

A decent oil pan but would benefit from being larger
This oil pan works decently but would be much better if it were slightly larger. At the size it is it is easy to miss the pan and make a mess. The pan holds enough oil for a bike or lawnmower but not enough for a car or truck. The plugs screw on well and don’t leak from my use. But the pan has inner lips that hold oil and make it hard to clean, would be much better if it were a smooth surface. The pan is made of thick plastic though and is well built overall, it just could be designed better.

Too small to avoid spilling/splashing!
Returning it as this was way smaller than expected!

Low profile
Worked perfectly for draining oil from zero turn lawnmower. Even cons with a spare inlet plug
