yo, congrats on the new CX-30!! honestly the trunk is tight so i totally get the struggle with stuff sliding around. for your situation, i highkey recommend skipping the official Mazda tray—it's like $100+ and things still slide on the plastic. instead, i've been using the Fortem Car Cargo Organizer with Reinforced Handles which is a total steal at around $25. it's got a non-slip bottom that actually stays put on the carpet, plus it's collapsible so it wont take up the whole floor when you don't need it.

Here's what I recommend for a budget setup:
- Get the Fortem Car Cargo Organizer for your groceries/gear ($25-30)
- Add some ElephantRest Trunk Cargo Net Hooks if you want to secure loose bags ($10)
- Maybe look at the STALWART 75-ST6027 Trunk Organizer for smaller tools ($15)

basically it's way cheaper than OEM and works better imo. i mean, the official one is durable but these third-party ones are sooo much more flexible for daily use... i think? anyway, gl with the new ride! peace

Seconding the recommendation above! Honestly, in my experience over the years, the official tray is way too slippery and can actually be a SAFETY risk if you've got heavy hiking gear flying around back there.

I've tried many setups, and since the CX-30 has that tight trunk, you gotta prioritize things that won't slide into the seatbacks. After a decade of driving small hatchbacks, here is what I found works best for safety and staying organized:

1. **Direct Carpet Grip**: Since you wanna avoid taking up floor space, look into Stayhold Cargo Organizer Brackets. They're basically hard plastic L-shaped blocks with crazy strong velcro on the bottom. You just stick 'em around your gear and they literally WILL NOT move.
2. **Safety First with Nets**: For your hiking gear, I'd skip the floor net and get an envelope-style one. I've been using the Genuine Mazda CX-30 Cargo Net BCKA-V1-540 which clips to the sides. It keeps everything upright so it won't tumble out when you open the hatch on a hill.
3. **Heavy Duty Collapsible**: If you need a bin, I prefer the Knodel Sturdy Car Trunk Organizer because it has non-slip strips on the bottom that actually work on Mazda's specific carpet grade.

Tbh, I'd go with the Stayhold blocks plus the OEM net. It keeps the floor mostly clear but secures the heavy stuff. gl!

Iirc, the official tray is kinda slippery for groceries, right? Honestly, I'd basically look into velcro-based blocks that grip the carpet directly... they keep everything REALLY secure without taking up any floor space.

Quick reply while I have a sec... I've been looking at the specs for some of these lately since I'm a bit of a nerd about trunk dimensions and grip coefficients. Honestly, the CX-30 carpet has a specific pile that works well with certain bases. I'm pretty satisfied with how some of these third-party ones handle lateral Gs when taking corners.

• WeatherTech CargoTech Containment System: These use a super grippy TPE material on the bottom. The friction coefficient is high enough that they wont budge even on aggressive turns. Plus, you can configure them for literally any gear shape.
• Starling's Car Trunk Organizer: If you want durability, look at this one. Its made of 1680D Oxford polyester, which is way tougher than the standard 600D stuff you find on cheap ones. The structural integrity is top notch. Tbh, I checked out some data on Mazda247 and Reddit and the consensus is that the WeatherTech blocks are the way to go if you want zero movement. Theyre technically superior to the official Mazda tray because they actually provide lateral support instead of just a flat surface.

Can confirm
