Allswell 4 in Memory Foam Mattress Topper Infused with Cooling Diamond Gel, Full

I was happy with my mattress but my partner complained the mattress was too firm, so I purchased this, thinking if it was too soft for my comfort it was not a bid investment. Well, let me tell you. The first night I slept on this, I did not move once. I was so comfortable! And when I woke up, my posture was perfect and my back felt better than it had in years. Every night since, I sleep so comfortably. It's just the right amount of support.

Great topper. Well worth the price! We have been putting off buying a new mattress, because we can't decide what we want (debating on splurging on a sleep%23). I bought this mattress topper to buy us some extra time, and it has totally transformed our mattress! I actually forgot we needed a new one!

I used this on a sleeper sofa I had to sleep on for a few months. It made the bed much more comfortable. Better than the bar I could feel through the thin mattress that was hurting my back each night. I just put this on top of the sleeper sofa mattress and then used a fitted sheet to bring the 2 together. I plan on using it on my full size bed when I return home next month. You'll want to rotate it about every 2 weeks to keep it firm and let air get back into it. I'm glad I went with the 4 inch version and not the 3 inch model. Much cheaper than a Dormeo.

I bought this in hopes it would alleviate issues with my current memory foam mattress. Used as a topper it did not; it was 1) uncomfortable and 2) hot. However, I remembered reading about benefits of using toppers underneath a foam mattress. My current Dormeo mattress is heavy %26 difficult to move but I managed to get it underneath. Surprise it worked! That uncomfortable spot is now comfortable. I can go a little while longer before buying a new mattress. As a topper I couldn't recommend but using the way I did might work for someone else too.

what you need to know. this mattress topper has confused me but I got it figured out. I purchased the king size because I needed something to make my soft mattress more firm because I was having body pain. like everyone else, I did not want to buy another mattress. they are expensive. I put the mattress topper on my bed according to the picture on the box which has the wavy side down. but when checking with chat GPT and online, the advice is to put the wavy side up. once I did that and also put it underneath my mattress cover, which is nice and thick, it is finally at a firm level. when I had the flat side up it was worse than my mattress. there is also conflicting information on whether to put it underneath the mattress cover or not. this was the only way it became firm for me. so, you might want to try it my way if it's not working for you because returning it is a pain because you cannot vacuum seal it again and trying to return a king size mattress topper makes you look like a total dweeb.

Not as described in terms of thickness, cooling half is non-supportive, indentations in foam do nothing and reduce potential thickness

I only give it a one. because it says cooling gel. I get very hot at night and thought this was going to help. I'm not if its the sheets or what. But this did not help me. I like this brand but this did not keep me cool. Plus they don't make the queen size one i brought before. That one helped me out over this one.

They say it's 4” thick but it's really not with the egg crate structure on bottom side. Too soft and weak and after a couple months sleeping on it I'll have to find another bed topper as this one already has lost its support and my back is hurting again. As for cooling aspect…. I can't tell the difference from past toppers. Overall way too expensive at $140 for queen size for what you get. If you need an actual 4” topper don't buy this one, it's a rip off.

I wanted to love this and have tried to make it work but simply could not handle that chemical smell another day! I let the topper air out for 11 days. I went as far as to let it air OUTSIDE in the SUN during warm days and the smell is still there. We slept on it one night and the comfort is amazing and relieved my back pain but my husband and I both woke up with a headache due to the lingering chemical smell. Anytime I'm around it I feel my throat burn after smelling it. So disappointing to find something that relieved my back pain to in turn put mine and my family's health at risk just by breathing.

This is a 1 inch piece of memory foam with a 3 inch egg cart type mattress cover that is 4 inches. It's like sleeping on a soft sponge. It's a misleading product. The part that is supposed to be the 1 inch memory foam is very questionable. Im not even sure that is memory foam
