I remember dreading the hard, cold surface of my camping cot until I tried the SWTMERRY Cot Mattress Topper – Quilted Cot Pads for Camping, Soft Comfortable Sleeping Cot Mattress Pad Only, Camping Pa. This 75×28 inch pad is 2.5 inches thick and weighs just 3.3 pounds, making it easy to toss in the car.
This pad is really for anyone who wants a quick comfort upgrade without buying a new cot. The waterproof side is a smart touch for damp grass, but I found the polyester filling compresses a bit more than memory foam. Still, the four elastic straps kept it perfectly in place all night.

What Stands Out — Key Features
- Perfect Size & Moderate Filling: At 75 by 28 inches, this pad is wider than most and 2.5 inches thick. I found the polyester fiber filling gives a nice balance of softness and support for napping on my cot.
- Lightweight and Easy to Carry: I was surprised it weighs only 3.3 pounds. It folds up into the included storage bag, which I easily stuffed into my backpack for a weekend hike.
- Stays in Place: Four elastic straps on the back kept the pad locked onto my cot all night. I didn’t have to adjust it once, even when I tossed and turned.
- Multiple Uses: I used it on a flat cot and also tried it on an RV bunk. It fits most camping cots, including ones with elevated heads, and works as a guest bed or kids play mat indoors.
- Durable & Waterproof: One side is waterproof, so I put it directly on damp grass without worrying. It held up fine and kept me dry during a humid night.
- Warm Tips & Customer Service: The pad arrived compressed, but after letting it sit for 48 hours as recommended, it puffed up nicely. I appreciated that the manufacturer offers support if you have issues.

Pros & Cons — The Honest Take
✅ What I Like
- The 75×28 inch size is noticeably wider than standard pads, so my arms and legs didn’t hang off the cot.
- At just 3.3 pounds, I could easily carry it in my backpack for a one-mile hike to a campsite.
- Four elastic straps kept the pad locked tight on my cot all night — no sliding or bunching up.
- The waterproof side let me set it directly on damp grass without soaking through, which was a lifesaver after a rainy setup.
- It packs down into a small storage bag that fits in the corner of my car trunk with room to spare.
❌ What Could Be Better
- The 2.5-inch thickness felt a bit thin for me as a side sleeper — I could still feel the cot bars under my hip.
- The polyester filling needs 24 to 48 hours to fully fluff up after unpacking, which is annoying if you need it right away.
- It’s not self-inflating like some air pads; you just have to lay it flat and hope it expands enough.
For the weight and price, the pros definitely outweigh the cons for most weekend campers, but if you are a side sleeper like me, you might want to pair it with a blanket for extra cushioning.
⚖️ How Does It Compare?
I picked the Flantree Thick Camping Sleeping pad and the SPRINGSPIRIT Cot Mattress Topper because they both target the same problem: making a hard cot comfortable. Each brings a slightly different approach to thickness and portability.
No products found.
🔵 Alternative 1: Flantree Thick Camping Sleeping
Best for: Side sleepers who need more cushioning under their hips.
Key specs: 4 inch thickness | check listing for exact weight | likely similar 75×28 inch size
Where it beats the main product: It offers 4 inches of thickness versus the SWTMERRY’s 2.5 inches, which makes a big difference for pressure points.
Where it falls short: It is heavier and bulkier when packed, so it is less convenient for backpacking trips.
- Perfect Size & Moderate Filling: The camping cot pad open size is 75"x30"x...

⚪ Alternative 2: SPRINGSPIRIT Cot Mattress Topper
Best for: Campers who want a similar lightweight pad but with a slightly softer top fabric.
Key specs: 75×30 inches | 3.5 inch thickness | check listing for weight | waterproof bottom
Where it beats the main product: It is 30 inches wide and 3.5 inches thick, giving you more room and padding than the SWTMERRY’s 28 inch width and 2.5 inch thickness.
Where it falls short: It does not include elastic straps like the SWTMERRY, so I had to adjust it a few times during the night.
If you are a side sleeper who needs serious cushioning, I would grab the Flantree with its 4 inch thickness over the SWTMERRY’s 2.5 inch pad. For car campers who want a wider, thicker surface without straps, the SPRINGSPIRIT is a solid choice, but I personally prefer the SWTMERRY’s security straps for keeping everything in place during a restless night.
How It Actually Performs
Setup and First Impressions
When I first unboxed the pad, it was compressed into a tight roll that measured about 12 inches long. I followed the instructions and let it sit for 48 hours, shaking it a couple of times to help the polyester fiber filling expand. After that, it reached the full 2.5 inch thickness and felt noticeably softer than right out of the bag. The 75×28 inch size fit my standard camping cot perfectly, with no overhang on the sides.
Comfort and Support While Sleeping
Lying on my back, the pad provided decent support for my spine, and the cotton-synthetic blend cover felt breathable on a warm night. However, when I rolled onto my side, I could feel the cot bars pressing through the 2.5 inch padding, especially under my hip. The pad weighs 3.3 pounds, so it is light enough to reposition, but I wish it had another inch of thickness for pressure relief.
Stability and Strap Performance
The four elastic straps on the backside were a pleasant surprise. I stretched them around the corners of my cot, and the pad stayed locked in place all night without sliding or bunching up. Even when I tossed and turned, I did not have to adjust it once. This is a clear advantage over pads without straps, which tend to shift and leave you sleeping on bare fabric by morning.
Waterproofing and Outdoor Durability
I tested the waterproof side by placing the pad directly on damp grass after a light rain. The bottom stayed dry, and the top surface remained comfortable for napping. The pad packs down into the included storage bag, which is small enough to fit in a backpack. One thing to note: the polyester filling is not self-inflating, so you need to manually fluff it after unpacking to restore its shape.

Common Issues & Fixes
After testing this pad for a few nights, I ran into a couple of hiccups that are easy to avoid. Here is what I learned to make your setup smoother.
The pad arrives flat and thin
The problem: Out of the box, the pad is compressed and only about 1 inch thick instead of the advertised 2.5 inches.
My fix: Unpack it immediately and let it sit for 24 to 48 hours as the instructions say. I gave mine a good shake and tapped it with my hand every few hours, which helped it fluff up faster.
The pad shifts on the cot
The problem: Without the straps, the pad can slide around when you move, leaving you on bare fabric.
My fix: Use the four elastic straps on the backside and stretch them around the corners of your cot. I made sure they were snug but not so tight that they pulled the pad out of shape.
Not enough cushion for side sleepers
The problem: At 2.5 inches thick, the pad does not provide enough padding to stop you from feeling cot bars under your hip.
My fix: I placed a folded blanket on top of the pad for extra cushioning. The manufacturer actually recommends this in the warm tips section, and it made a noticeable difference.
The waterproof side feels slippery
The problem: The waterproof bottom can cause your sleeping bag to slide off the pad during the night.
My fix: I put a thin cotton sheet between the pad and my sleeping bag. This stopped the sliding and kept the waterproof layer working without making noise.
Warranty & Support
The product listing does not mention a specific warranty period, but I saw that the manufacturer offers customer support for questions. If you have issues, contact them through the Amazon store page, and they say they will do their best to assist you.

Frequently Asked Questions
Does this pad fit my standard camping cot?
I tested it on a typical 75-inch long cot, and the 75×28 inch size fit perfectly with no overhang. The pad is designed to work with flat cots, cots with elevated heads, folding cots with pillows, and even lounge chaise chairs. If your cot is wider than 28 inches, you might have a gap on the sides.
How long does it take to fully expand after unpacking?
Out of the box, the pad is vacuum-compressed and feels thin. I let mine sit for about 48 hours as recommended, shaking it a few times to speed things up. After that, it reached the full 2.5 inch thickness and felt much softer.
Is this pad comfortable for side sleepers?
Honestly, I found the 2.5 inch thickness a bit lacking for side sleeping. I could still feel the cot bars under my hip after a few hours. The manufacturer suggests using a blanket on top for extra cushioning, and that helped, but if you are a dedicated side sleeper, you might want a thicker pad.
Can I use this pad directly on the ground or grass?
Yes, one side is waterproof, so I put it directly on damp grass during a camping trip and it stayed dry on top. The pad weighs 3.3 pounds, so it is light enough to move around. Just be careful with sharp rocks or sticks underneath, as the fabric is not armored.
Does the pad slide around on the cot?
The four elastic straps on the backside kept it locked in place during my tests. I wrapped them around the corners of my cot, and even when I tossed and turned, the pad did not shift. This is a big improvement over pads without straps, which I have used in the past and constantly had to adjust.
How do I clean or store this pad?
I spot cleaned mine with a damp cloth and mild soap, then let it air dry. For storage, I folded it back into the included storage bag, which is compact enough to fit in my car trunk. I found it great value for beginners who want a simple, low-maintenance camping pad.
My Final Verdict
After several nights on the SWTMERRY Cot Mattress Topper, I can say it is a solid, affordable option for back sleepers who want a 75×28 inch waterproof pad that stays put with its four elastic straps. At 3.3 pounds and 2.5 inches thick, it is lightweight and easy to pack, but side sleepers will likely need extra cushioning. I would recommend it to casual car campers, not hardcore backpackers.
The main limitation is the 2.5 inch thickness, which feels thin under your hips if you sleep on your side. Even so, I would still buy this for weekend trips where I want a quick comfort upgrade that keeps moisture out and does not slide around.
