Lazyzizi Mattress Wedge Only, 7-Inch Queen Inclined Bed Wedge Mattress Topper for Acid Reflux, GERD, Neck & Back Pain, Snoring, Adjustable Elevator Under Mattress Support for Bedroom

Excellent product but would be better if they showed metric measurements. I converted the inch things into metric and then chose the option closest to my double Emma mattress. Once it arrived I opened it and left it for 48 hours to fully expand. Fits well under my mattress and I am very happy with it.

Very good product..had on top of my mattress . Best night's sleep ever since.

Okay so I have been having problems sleeping and problems with my feet mainly pins and needles, when waking up, have slightly high cholesterol but not massively high and was recommended to prop myself up a bit when sleeping to aid circulation tried a few things but they were all a bit of a hassle since I could not just raise one end of my bed 5 inches because it is a box base in two parts I opted for this in the 5" version. Must say that after waiting 3 days for it to re-inflate after in packing I placed it UNDER my mattress to spread the weight out rather than on top of it as memory foam I find gets too hot when sleeping on it directly. First few days it felt a little wierd being on a slight slope but now really don`t notice it and have found my sleep to be good and my feet feel fine in the mornings so I am happy with it. Hence the 5 stars. It arrived quickly and was easy to get upstairs as it was vacuum sealed so quite small to begin with.

The product is very good but be aware that these mattress wedges are not international standard sizes, they are American sizes (in imperial measurements). For example, the single size (what the Americans call twin' is about 6cm (2½") too wide and sticks out at the side. Also be aware what they call Queen size is actually King size, and their King size is actually Superking. If it was not for the sizing, this would be a 5-star review.

Excellent took some getting used to but very pleased

This is NOT king size - it is 75 and a half inches wide not 60” which means I now have to cut 15+inches off!!!!! In metric it is 192cm!

I have been looking for a full length wedge like this for the last year but the only UK one I previously found was much more expensive, so was very happy to find this one. It is sturdy so under my mattress for reflux problems. I personally think it would be uncomfortable on top of a mattress but is working very well under it. Very happy with my purchase

Very useful to have a full length wedge under the mattress for addressing heartburn. Shame it is so expensive considering it is just a bit of foam (farmore expensive than a top end mattress topper).

So much easier to install than the foot risers you put under the feet of your bed. It comes vacuum packed, but quickly regains it shape. I put it under the mattress in the hopes it retains its wedge shape longer. In doing this over, I would have bought the 5 inch wedge over the 7 inch, as the latter has made the bed REALLY high. But it's working fine. You can't feel that you are laying on an incline also. Time will tell if this mattress insert improves my acid reflux, but the previous one did.

I bought this as opened package and I got it for less than. I felt the difference on the first night I helped my gerd symptoms and I can breath so much better

Muy buen colchón,lo recomiendo ampliamente, lo puse debajo de mi colchón y tengo la elevación perfecta, luego luego note la diferencia en cuestión del reflujo ya que estaba broncoaspirando; había utilizado la cuña y no me funciono; no te resbalas como dice en otros comentarios

Ideal y comodo

My GERD has recently dipped down worse again after being lazy with it the last few years and I have a likely hiatal hernia + acid reflux. Back in the day when I was trying harder I used those bed risers and lifted the top half of my bed. But this likely puts strain on your bed frame. I was lucky back then because it was a solid wood bed frame. They don’t make stuff like they used to so I knew my Amazon bed frame was not about to survive that treatment. I found these foam mattress wedges and I knew they were the right call. I have a THICK Original Mattress Factory mattress. I got the 7” one and I’m so glad I did. It raises you up just right. I have it underneath my mattress so it stays completely clean. Will you slide down a little when you use these? Yeah maybe. If you raise the head of your bed with risers you’ll also slide down. But it’s not crazy. Just depends how much you move around at night honestly. I was also happy that it didn’t have much of a smell when opening it up. Just that fresh foam smell. It’s also true to size for my Queen bed. Sits right inside the frame area and doesn’t overhang. It was weirdly easy to install even with my heavy mattress and I was by myself. Had to use some elbow grease but I made it happen. Great bang for your buck and it doesn’t harm the integrity of your bed frame or mattress which I love.
