Customer Reviews for MELLOW 4 in. King Cooling Gel Egg Crate Memory Foam Mattress Topper

I got this mattress topper because I got a new foam mattress and it was WAY too hard. I am used to sleeping on a very soft/mushy mattress. This topper gets the job done - especially for the price. It does not feel like "I'm sleeping on a cloud", like how I wanted however, it does provide some memory foam in the tempur-pedic way I could describe, I would say it's between medium mushy/hard. I would've preferred the gel to be a little more "mushy"/or cool. I don't notice the cooling. It is the full 4 inches.

Bought this topper for a new mattress that was too hard. Ordered in store and it shipped to my home, received discount and free shipping. Unraveled and placed on my bed for 48 hours, it plumped right up and measurements were exact. Was very comfortable to sleep on so far. It does not shift, stays put. Glad I got the four inch, needed it for orthopedic problems.

Droops downward in the middle and is actually not cooling at all—gets pretty warm. Expected to not encounter those two problems specifically which is why I bought it. It is very soft though.

Very stiff. Not comfortable at all! I got this bc im 5 months pregnant and needed something to help with my back. This does nothing.

This memory foam is amazing!! My wife put it in our camper on top of the mattress. She then put a mattress topper on it. It is cooler as well. She is a bigger person and she said she was shocked how comfortable it was she slept on it for 3 nights. I took a nap on it it is amazing. I don’t have a picture of it by itself but can’t beat the 4 in thickness.

This topper is so comfortable I never want to leave my bed, I sleep like a baby on it and love to lay on it any chance I get. I personally like the egg crate style over the flat ones but that’s just me. Bottom line is I would definitely recommend it, best money I’ve spent in a long time!

Purchased this for a sofa bed that had an older, uncomfortable mattress. Added a 2” down alternative mattress cover and the combination is way more comfortable than any sofa bed I’ve ever slept on. We bought the 3” version of the foam topper and it was almost that full within a short period after opening it up. I have no qualms about offering a sofa bed to our guests as this combination is so luxurious.

Very good for my back problems!

My back no longer hurts. Wirth every penny. Veey thick snd comfortable, highly recommend

The ad states this is a 4" cooling gel.... It is 3" at best and the cooling gel is totally non existent. This makes the bed so hot you wake up several times a night. Even started sleeping with the fan on - doesn't help. This topper has absolutely no support so all of your "pressure points" are very sore every morning . DO NOT RECOMMEND

Really made the sofa/hide away bed more comfortable

Was not quite what I had hoped it would be

High quality product. We use it in our adjustable bed. It’s very comfortable and stays in place!

Very comfortable bought another for my mom who was complaining about her mattress: she loves it also.

This product was on sale thru HD. Shipped to store for free shipping. Looking to add some comfort to a firm mattress without breaking the bank. For free shipping, I had the mattress shipped to store. Mattress topper arrived at the store in a timely manner. Unwrapped the mattress topper, & let it expand for a couple of days. Measured topper, and it was 4" as advertised. No overbearing chemical smells from unboxing but I let it air out and expand for a couple of days. Placed on top of queen mattress, and the size fits perfectly. Time will tell, as I've only had 1 night to sleep on the topper but I will say it was very comfortable, almost to comfortable. Overall, I am pleased with this purchase. To anyone who may consider this topper, I would unwrap, & let the topper expand for at least 3 - 4 days before putting on your mattress. I will update this post in a month or two, once I've had the chance to break it in, and give it a fair review.

For the price it’s definitely worth the purchase!

This works well for a couch that makes into a spare bed - adds the extra "cush" that the couch surface does not have. I'm sure it will work for permanent use on a bed that needs extra comfort.

Definitely 4 inches and loving every inch of it for sure. I was hoping to add more comfort to a firm mattress that is fairly comfy. It took a few hours to expand and it had no odor at all. I placed on top of my mattress and covered it with my waterproof mattress cover then the fitted sheet. Instant comfort already! If your not sure, do take the plunge.
