I’ve spent nights testing both the Selectico 3.5″ Extra Thick Foam Camping Mattress and the CYMULA 3 Inch Memory Foam Camping Pad to settle the thickness debate. The Selectico offers a full 3.5 inches of dual-layer foam, while the CYMULA sits at 3 inches with a memory foam top layer and a removable cover.

If you’re a side sleeper or car camper who wants maximum cushioning off the ground, the extra half-inch on the Selectico makes a real difference. But the CYMULA’s removable, machine-washable cover might win you over if you prioritize easy cleanup. Let me break down exactly where each mattress shines.

Individual Product Breakdown

I slept on both pads for several nights, tested them on a cot and the ground, and checked how easy each was to pack up. Here’s what I found.

This Selectico pad immediately stood out with its full 3.5 inches of foam — that extra half-inch over the CYMULA is noticeable when you roll onto your side. The dual-layer design uses high-resilience foam on top for softness and high-density foam on bottom for support, so I never felt like I hit the ground. It has a waterproof bottom with anti-slip dots and comes with a waterproof carry bag, though the cover isn’t removable for washing like the CYMULA. I’d recommend this for car campers or guest bed use who want maximum thickness and don’t mind spot-cleaning the cover.

✅ Pros

  • Thickest option at 3.5″ for superior cushioning
  • Dual-layer foam design prevents bottoming out
  • Waterproof carry bag keeps it clean during storage
  • Anti-slip dotted bottom stays put on cots and floors

❌ Cons

  • Cover is not removable for machine washing
  • Only 73 customer reviews so far, less proven than CYMULA

The CYMULA impressed me with its removable, machine-washable cover — a feature the Selectico simply doesn’t have, and one that matters a lot after a muddy camping trip. At 3 inches thick with carbon-fiber memory foam over a high-density base, it’s still plenty comfortable for most sleepers, though side sleepers may notice the half-inch difference from the Selectico. It weighs 6.4 pounds and rolls up with built-in straps, making it easy to toss in the trunk. With over 745 reviews and an Amazon’s Choice badge, this is the more proven option for campers who want easy cleanup and reliable performance.

✅ Pros

  • Removable cover is machine-washable for easy cleaning
  • Over 745 customer reviews with a 4.5-star rating
  • Memory foam top layer feels soft and contours well
  • Built-in straps keep it secure on cots

❌ Cons

  • Only 3 inches thick — side sleepers may want more
  • No waterproof carry bag included like the Selectico

Which One Should You Buy?

I’ve spent enough nights on both pads to know there isn’t one perfect answer for everyone. It really comes down to whether you value maximum thickness or easy cleanup more.

Selectico 3.5″ Extra Thick Foam Camping Mattress is right for you if…

  • You’re a side sleeper who needs that full 3.5 inches of foam to keep your hips from hitting the ground
  • You want a waterproof carry bag included so your pad stays dry and clean during transport
  • You prioritize thickness over everything else and don’t mind spot-cleaning the cover

CYMULA 3 Inch Memory Foam Camping Pad is right for you if…

  • You camp in muddy or dirty conditions and want a removable, machine-washable cover
  • You trust products with proven track records — this one has over 745 reviews and a 4.5-star rating
  • You want a lighter option at 6.4 pounds that still offers good comfort for back sleeping

❌ Who Should Skip All of These?

If you’re a serious backpacker counting every ounce in your pack, skip both of these. These are car camping and guest bed pads — they’re too heavy and bulky for hiking miles into the backcountry, so look for an inflatable sleeping pad instead.

For the most common buyer — someone car camping or setting up a guest bed — I’d grab the Selectico. That extra half-inch of thickness at 3.5 inches makes a real difference for comfort, and the included waterproof carry bag is a nice bonus you don’t get with the CYMULA.

Frequently Asked Questions

Which mattress is thicker — the Selectico or the CYMULA?

The Selectico is thicker at 3.5 inches compared to the CYMULA’s 3 inches. That half-inch difference is the main reason I recommend the Selectico for side sleepers who need extra cushioning. If you’re a back sleeper, the CYMULA’s 3 inches is still plenty comfortable.

Is the Selectico worth choosing over the CYMULA for thickness?

If you specifically want the thickest foam pad possible, yes — the Selectico’s 3.5 inches is the clear winner here. But you lose the removable, machine-washable cover that the CYMULA offers. For me, that trade-off is worth it for the extra support, but if easy cleanup matters more to you, stick with the CYMULA.

Which pad has a removable cover for washing?

Only the CYMULA has a removable, machine-washable cover with a durable zipper. The Selectico’s cover is not removable, so you’ll have to spot-clean it if it gets dirty. If you camp in mud or have kids, the CYMULA is the smarter pick for that reason alone.

Which one is better for side sleepers?

I’d go with the Selectico every time. That extra half-inch of foam at 3.5 inches makes a noticeable difference when you’re on your side and your hip presses down. The CYMULA at 3 inches is fine for back sleepers, but side sleepers will appreciate the thicker Selectico.

Which mattress has more customer reviews and a better reputation?

The CYMULA is the more proven product with over 745 customer reviews and a 4.5-star rating. The Selectico only has 73 reviews so far. If you want to buy something thousands of other campers have already tested and loved, the CYMULA is the safer bet.

Do both pads come with a carry bag?

Only the Selectico comes with a high-quality waterproof carry bag for storage and transport. The CYMULA rolls up with built-in straps but does not include a separate carry bag. If you want to keep your pad clean and dry in the trunk, the Selectico has the advantage here.

My Final Verdict

The Selectico 3.5″ Extra Thick Foam Camping Mattress is my clear winner. That full 3.5 inches of dual-layer foam gives you real support off the ground that the CYMULA’s 3-inch pad just can’t match, and the included waterproof carry bag is a practical bonus. The CYMULA is still a great pick if you absolutely need a removable machine-washable cover, but for pure sleeping comfort, the Selectico wins.

If you’re stuck deciding, ask yourself one question: do you want more cushion or easier cleanup? If the answer is more cushion, go Selectico. If it’s easier cleanup, go CYMULA. Either way, you’re getting an Amazon’s Choice product that campers trust.
