Size: Queen (80x60 Inch)
This memory foam mattress topper is incredibly comfortable and has made a huge difference in my sleep quality. The 5-inch thickness provides great support while still feeling soft and cushiony. It fits my queen size bed perfectly, and the four elastic straps keep it securely in place all night. The cotton top is breathable and smooth, keeping me cool and comfortable even during warmer nights. The overall quality feels premium, and it adds a luxurious, hotel like feel to my bed. For the price, it’s an excellent value. Highly recommended for anyone wanting to upgrade their mattress without buying a new one.

Five Stars – So Comfortable and Worth Every Penny! I am absolutely delighted with the WhatsBedding 5 Inch Memory Foam King Mattress Topper! From the moment I unpacked it, I could tell it was a high-quality product. The topper is extremely plush, and the memory foam provides excellent support – it feels like sleeping on a luxury hotel bed every night. The breathable and soft pillow top makes a noticeable difference in comfort, and the elastic straps keep it securely in place on my mattress. It fits perfectly on my king-sized bed, and I woke up with significantly less back pain from the very first night. If you’re looking to transform your bed and improve your sleep quality, I highly recommend this mattress topper. It’s well worth the investment! Five stars all the way!

I recently bought the WhatsBedding 5 Inch Memory Foam King Mattress Topper, and it has completely transformed my bed. The comfort level is amazing — the memory foam is soft, supportive, and feels like sleeping on a cloud. The 100% cotton top is very breathable and gives it a premium feel. I also love the four elastic straps; they keep the topper perfectly in place with no shifting at all. It adds the perfect amount of softness while still providing good support. I noticed a big difference in my sleep quality from the very first night. If your mattress feels too firm or you just want extra comfort, I highly recommend this topper. Great quality, super cozy, and definitely worth the price!

I’m extremely impressed with this mattress topper! The memory foam feels wonderfully supportive, and the cotton pillow-top layer adds incredible softness. It instantly made my bed much more comfortable and helped me sleep better from the first night. The breathable design keeps me cool, and the elastic straps hold everything securely in place. The quality is excellent, and it looks just as good as it feels. I highly recommend this topper to anyone wanting to upgrade their mattress easily and affordably!

I love it, it’s comfortable and I sleep sooo much better. It’s soft and comfortable. I don’t like their logistics, this took almost a month to receive because it was shipped somewhere else, which mean shipping couldn’t be updated after 2 weeks and I had to guess when or if it was coming in. This is such a disappointment to such a high quality topper.

It’s soft (almost silky), it’s comfy, and it’s water resistant...the pillow top is soft to the touch and it is cozy. Like a foam mattress, it arrives vacuum sealed and inflates as the material breathes and relaxes. At first we were optimistic as it seemed like it might keep expanding but stopped well short of what we anticipated. The main issue is the cover is NOT cooling as advertised, it’s closer to the feeling of sleeping on flannel sheets, which is perfectly fine for others, just not us. We keep our bedroom at less than 68 degrees and after two weeks of testing we feel like we’ve lost the benefit of the gel pad in our mattress and have both woken up sweaty in the morning. Any extra curricular activity is also difficult to cool down from, again it just isn’t cooling. Another note regarding the pillow top, it is soft to the touch but too thin, more of a thin pad than a pillow top (like a cross between a duvet and goose feather comforter). Where this topper would be perfect: if you run cold and need added warmth and already have a soft mattress, this is perfect. It will protect from water, create a soft veneer for your mattress, it will keep you warm, and even the king size will easily fit in the washing machine. Why it doesn’t work for us: the cotton is not breathable and holds heat and is simply not ‘pillow’ enough, the topper does not soften a firm mattress. We will likely switch to a foam topper for softness w thin bamboo protector for better breathability. Overall we were disappointed for our use, but can see how others might like it.

Very thick and comfortable. Better buy and protect my new mattress. Warm but not too hot during cold weather. Fits perfectly as well.

I used to sleep directly on my mattress and it always felt cold and uncomfortable. After I added this mattress topper, my sleep completely changed. It’s soft, warm, and very cozy. Now I can finally sleep through the night without waking up.If your mattress feels too firm or cold, this topper makes a huge difference. Highly recommend 🥰
