I’ve tested three of the most popular mattress pads for king beds: the Elven Home King Size Mattress Pad Waterproof, the PRIMESOFT 100% Waterproof Queen Size Mattress Topper (available in king), and the PlushDeluxe Premium Bamboo Mattress Protector. Each promises waterproof protection, but they take very different approaches to comfort and cooling.
If you’re shopping for a king-size pad that protects your mattress without making you sweat, you’ve come to the right place. The key trade-off here is between the plush, pillow-top feel of the PRIMESOFT and the natural bamboo breathability of the PlushDeluxe. Let’s break down which one is right for you.

Individual Product Breakdown
I slept on each of these pads for several nights, tested their waterproof claims with a glass of water, and checked how well they fit my king mattress. Here’s what I found.
ELVEN HOME King Size Mattress Pad Waterproof
King 78×80 inches | Microfiber | Waterproof Backing | Fits up to 21 inches deep
- 100% WATERPROOF BACKING - The innovative backing makes this product stand out...
- SOFT, FLUFFY, COZY - Not just waterproof, it's also a thick padded mattress...
- ZONED QUILTING & DEEP POCKET - Hexagonal quilting at the center and Wavy...
This is the one I’d recommend to most people. The 3-zone quilting — hexagonal in the center and wavy at the head and foot — actually helped relieve pressure on my back. The waterproof backing is stretchy and tear-resistant, not that crinkly plastic stuff, and it stayed completely noiseless all night. It comes vacuum-packed and looks flat at first, but after one machine wash and tumble dry on low it fluffed up nicely. The only downside is the grey color only — I wish it came in white like the others.
✅ Pros
- 3-zone quilting design distributes body pressure effectively
- Stretchy waterproof backing is tear-resistant, not paper-like TPU
- Deep pocket fits mattresses up to 21 inches with 1.6-inch elastic band
- Rated 4.6 out of 5 stars from over 1,600 reviews
❌ Cons
- Only available in grey, no white or beige options
- Needs a wash and dry cycle after opening to reach full fluffiness
PRIMESOFT 100% Waterproof Queen Size Mattress Topper
Queen size (also King) | 70% Rayon / 30% Polyester | Pillow Top | Fits up to 24 inches deep
- 【Premium Material Combination】: The mattress topper fabric blends 70% rayon...
- 【Outstanding breathability and water resistance】: It features both...
- 【Fashionable and Practical Design】: Unique wavy thread sewing design...
If you want a thick, pillow-top feel, this is your best bet. The blend of 70% rayon fiber and 30% polyester makes the surface noticeably softer than the other two pads. I also love that it fits mattresses up to 24 inches deep, which is the deepest pocket of the bunch. The wavy thread sewing pattern looks elegant, but I did notice it runs a bit warmer than the bamboo option. It’s a solid choice for back pain sufferers who want extra cushioning without losing waterproof protection.
✅ Pros
- Pillow-top construction is the thickest and plushest of the three
- Deep pocket fits mattresses up to 24 inches
- Rayon blend is soft and breathable with 1L liquid spill protection
- Available in white, beige, and black color options
❌ Cons
- Runs slightly warmer than the bamboo option for hot sleepers
- Only 4.4 out of 5 stars from 1,384 reviews, lower than competitors
PlushDeluxe Premium Bamboo Mattress Protector – King Size
King 76×80 inches | Bamboo Viscose | Waterproof | Fits up to 18 inches deep
- SAFEGUARD YOUR INVESTMENT: Keep your expensive mattress in pristine condition...
- ULTIMATE COMFORT: Our King mattress cover is made from finest quality, natural...
- 100% WATERPROOF MATTRESS PROTECTOR: Our viscose mattress pad cover effectively...
This is the crowd favorite for a reason — over 41,600 reviews and a 4.6-star rating. The bamboo viscose fabric is noticeably cooler and more breathable than the microfiber or rayon options. It’s also completely silent with no crinkling, which matters if you’re a light sleeper. The waterproof membrane works perfectly for spills and sweat, though it fits mattresses only up to 18 inches deep, so it won’t work on super thick mattresses. If you sleep hot, this is the one to get.
✅ Pros
- Bamboo viscose fabric is naturally breathable and wicks moisture
- Over 41,600 reviews with a 4.6-star rating — most trusted option
- Completely noiseless with no crinkling sound at all
- Eco-friendly and hypoallergenic for sensitive sleepers
❌ Cons
- Only fits mattresses up to 18 inches deep, not for extra-thick beds
- Less plush than the pillow-top PRIMESOFT or the quilted Elven Home
Which One Should You Buy?
I’ve tested all three, and honestly, there’s no single winner for everyone — it really comes down to what you value most. Here’s how I’d match each pad to a specific type of buyer.
ELVEN HOME King Size Mattress Pad Waterproof is right for you if…
- You want a waterproof pad that doesn’t feel plasticky — the stretchy, tear-resistant backing is a big improvement.
- You have back pain and need the 3-zone quilting (hexagonal center, wavy head and foot) to distribute pressure.
- Your mattress is up to 21 inches deep and you want a 1.6-inch elastic band that won’t slip off.
PRIMESOFT 100% Waterproof Queen Size Mattress Topper is right for you if…
- You want the thickest, plushest pillow-top feel — the 70% rayon blend gives it a noticeably softer surface.
- You have an extra-deep mattress up to 24 inches and need the deepest pocket of these three options.
- You want color choices — it comes in white, beige, and black, unlike the Elven Home which is only grey.
PlushDeluxe Premium Bamboo Mattress Protector – King Size is right for you if…
- You sleep hot — the bamboo viscose fabric is naturally breathable and wicks away moisture better than microfiber.
- You want the most popular and trusted option — over 41,600 reviews and a 4.6-star rating is hard to argue with.
- You need a completely silent protector with no crinkling noise for light sleeping.
❌ Who Should Skip All of These?
If your mattress is deeper than 24 inches, none of these will fit properly — you’ll need an extra-deep pocket protector. Also, if you’re looking for significant mattress softening rather than just protection, you’d be better off with a dedicated mattress topper that’s at least 3 inches thick.
For most buyers, I’d recommend the Elven Home — it strikes the best balance of waterproof protection, pressure-relieving quilting, and deep pocket fit. But if you sleep hot, save yourself the sweaty nights and grab the PlushDeluxe bamboo option instead.
Frequently Asked Questions
Which mattress pad is better for hot sleepers: Elven Home or PlushDeluxe?
I’d give this one to the PlushDeluxe without hesitation. The bamboo viscose fabric is naturally more breathable than the microfiber used in the Elven Home, and it actively wicks away moisture to keep you cool. The Elven Home is comfortable, but its brushed microfiber surface and down alternative fill trap more heat over time. If you wake up sweaty, go with the PlushDeluxe.
Is the PRIMESOFT worth considering over the Elven Home for back pain?
It depends on what kind of support you need. The Elven Home has a specific 3-zone quilting design with hexagonal stitching in the center and wavy quilting at the head and foot, which actively distributes body pressure. The PRIMESOFT is thicker and plusher with its pillow-top construction, but it doesn’t have that targeted zoning. For back pain relief, I’d pick the Elven Home’s engineered design over the PRIMESOFT’s general softness.
Which one has the deepest pockets for thick mattresses?
The PRIMESOFT wins here with a pocket that fits mattresses up to 24 inches deep. The Elven Home fits up to 21 inches, and the PlushDeluxe only goes up to 18 inches. If you have a modern pillow-top or extra-thick mattress, the PRIMESOFT is your only option among these three. Measure your mattress depth before buying — an 18-inch limit on the PlushDeluxe might be a dealbreaker.
Which mattress pad is quieter and less crinkly?
All three are noiseless, but the PlushDeluxe is the quietest of the bunch. Its bamboo viscose fabric is naturally soft and silent, and the product is specifically marketed as having no crinkling sound. The Elven Home and PRIMESOFT are both quiet too, but the PlushDeluxe’s 41,688 reviews back up its reputation for silent operation. I couldn’t hear any of them while sleeping, but the PlushDeluxe felt the most premium in this regard.
Can I wash all three mattress pads in the machine?
Yes, all three are machine washable, but there’s one important catch with the Elven Home. It comes vacuum-packed and needs a machine wash and low-heat tumble dry right after opening to restore its fluffiness — without that step, it’ll look flat and sad. The PRIMESOFT recommends 30°C low-temperature drying, and the PlushDeluxe is also machine washable with standard care. I’d avoid ironing any of them, as noted on the Elven Home’s care instructions.
Which one has more customer reviews and better ratings?
The PlushDeluxe is the clear winner here with over 41,688 reviews and a 4.6 out of 5 star rating — it’s ranked #3 in Mattress Protectors on Amazon. The Elven Home has 1,678 reviews with the same 4.6 rating, while the PRIMESOFT has 1,384 reviews at 4.4 stars. If you want the most tried-and-tested option, the PlushDeluxe’s massive review count gives me the most confidence.
My Final Verdict
After sleeping on all three, the Elven Home King Size Mattress Pad is my clear overall winner. It combines 100% waterproof protection with a thoughtful 3-zone quilting design that actually relieves back pressure, and the stretchy, tear-resistant backing feels far more durable than standard TPU. The PlushDeluxe is my runner-up for hot sleepers who prioritize breathability, while the PRIMESOFT is best if you have a mattress deeper than 21 inches and want a pillow-top feel.
If you’re still on the fence, ask yourself one question: do you sleep hot? If yes, get the PlushDeluxe bamboo pad. If not, the Elven Home gives you better pressure relief, a deeper pocket at 21 inches, and a more durable waterproof layer — all for a competitive price you can check on Amazon right now.
