I’m really happy with the Member’s Mark Pillow Top Gel Memory Foam Mattress Topper. It’s been a solid upgrade to my mattress. If you’re looking for something that makes your bed feel softer and more supportive while keeping the heat down, this topper is a great option.

Topper helps me stay asleep

I put my Member’s Mark memory foam topper on an existing 8” mattress and it gives my bed just the right amount of softness and support. The stretch cover fits nicely over the topper and mattress allowing for a very comfortable nights’ sleep. I highly recommend!

Highly Recommend

The Member's Mark 4" Pilllow Top Gel Memory Foam Mattress utilizes high density gel memory foam for exceptional support, the mattress topper maintains its original, like new feel even after extensive use. It acts as a transformative addition, making your mattress more comfortable. Whether your mattress is too firm or needs a boost, the topper provides a softer feel while retaining essential support. I highly recommend it to anyone experiencing back discomfort because you will  feel more support with no back aches or pains.

Member’s Mark 4" Top Gel Memory Foam Mattress

Felt like I was sleeping in a different bed. It arrived wrapped around in plastic. When the topper got unfolded, it opened nicely. No dents marks. When you press foam with hand and remove it, the foam reshapes quickly. I will be buying more for the other beds.

Sleeping on a Cloud

I love this topper. I probably needed a new mattress and even though this obviously isn’t a mattress, it does offer than feeling of a new life! It’s very comfortable - definitely mirrors my ideal firmness. I love that it fits seemlessly into my bed and my covers went over the top easily. You can’t tell it’s there in terms of the aesthetics!!! I also love how it makes my bed higher and just more comfy. Very happy with this.

Lovely addition to my bed!

This mattress topper is nice and thick! Provides a lot of supportive cushioning and I haven’t had any issues with sagging yet. It has a cover that is also thick and is a cooling topper! I really love that it stays cool because I find that these memory foam mattresses always sleep hot. The cover is easy to wash and seems really well made. It fits nicely under my sheet, but I do buy the deep pocket sheets. Really happy with this mattress topper! I know stay cool and comfortable all night!! Plenty of cushioning.

So happy for cooling feature!!

This is a game changer the material first of all just feels like it’s a part of your mattress it’s not hot it’s not itchy. The softness is just right, it does not make your mattress any less soft or firm it’s just an added comfort piece. My kids say they absolutely love the difference it makes

Comfortable and nice

This foam topper is very comfortable to sleep on and easy to unpackage. There is no unpleasant smell from the foam like I’ve had on ones in the past. The only minor complaint is that the mattress cover needs to be a little bit deeper pocket. My mattress is not overly thick and with the topper the cover barely fits onto my mattress. Otherwise great product!

No nasty smell in the foam and very comfy!

Very comfortable! This was a great addition to my daughters bed to add a nice cloud like comfort. It's a little larger than the bed so it looks weird with just a sheet on, so adding the comforter definitely made it look nicer. She said she seems to sleep better since using.

Comfy!

This pillow top gel memory foam mattress pad completely upgraded the feel of my old mattress. It’s incredibly soft—just the right mix of cushion and support—and the cooling gel actually works. I sleep much more comfortably now and no longer wake up overheating.

It definitely saved me from having to buy a whole new mattress, which I was seriously considering.

It does come with corner straps, which help a little, but the pad still shifts around a bit during the night. It’s not a dealbreaker, just something to be aware of if you’re a restless sleeper. I do wish it had a more secure fit or deeper side panels.

Overall, the comfort and cooling factor make it worth it—and my back agrees!

Super comfortable and cooling

This mattress topper way too soft and retains heat.  It does not support your back. I do not recommend it.
