Very Comfortable
Very comfortable and the perfect size for a sofa. I tend to get back spasms because of a mixed connective disorder I have and when I don’t want to sleep in my bed, I can have a super comfy place to rest on the couch. The optional cover is something I recommend with this. You can just unzip it and throw it in the wash and it’s good to go again. Well made, never loses its shape. I do actually have a good quality of sleep on this when my back is in a spasm so it’s very recommended for those times when you want something comfy and well made. Thicker than most other similar items. I very much recommend this.

COMFY – PERFECT SIZE FOR A COUCH! Wonderfully Marshmallowy – yet no back aches.
Perfect size for my couch for friends sleeping over. I’ve slept on it for a while and it is like sleeping on a marshmallow – sooooo comfy (and my back doesn’t hurt at all!) Easy to roll up and wrap with included straps

Roll up mattress topper
I’m a sailor. This mat topper was the perfect size for my rack on a carrier ship and was so comfy. You have to pick the smallest twin size for it to fit perfectly in your rack. It’s unzips for easy cleaning, and rolls up nicely with the straps given. Good quality. Would use for camping and other things too. Also, not too plushy. It’s the perfect balance of plush and firmness if you’re like me and need good support. Yeah it’s big when packing up but it’s not heavy.

The fit is perfect and comfortable
This mattress topper it perfectly on a pull out chair bed.. it would probable be perfect for a cot. The company advises that it be left out to air for a couple of days which we did, but I found the odor to be minimal. The covering is soft and fits the matress perfectly. If anything, it could be a bit firmer, but for our use on top of the pull out chair bed, it was perfect. Good value for the price.

Love this mattress, it makes my cot so much more comfortable than with the Thermarest camping mattress I put on top of it previously. Worth the money.

A struggle to Roll and Secure for Transport
This item is advertised as being 4″ thick… perhaps, if you order the extra thick cover. Speaking of the cover that comes with this product you need to put a sheet on top of it as you will find it difficult to turn over to your right or left side. Now, here is the really difficult part… rolling this thing up and using the strap to secure it! though I’m 78, I lift weights and am in good shape. You want to transport this mat to your motel room for the kids or whatever; good luck rolling it up and having the strap snap into place! I rolled this mat as small as possible – it took a few tries as the first two would not allow the strap to completely encircle the mat. On the third try, while placing as much of my body weight as I could to keep the thing rolled up, I could barely get the strap to snap into place. Looking at this contraption of a strap… it being plastic and all, not long for a life span under all that pressure of keeping the mat rolled up for transportation (in my opinion)! If the company had given the length of the strap at least two more inches… I think that would have been a game changer for me. Life has enough struggles, I didn’t need this to be one of them.

I purchased the size narrow twin but unfortunately, it was too narrow for me so I had to purchase the full twin size.When preparing to box the item again, I was having a hard time putting it back in the box as it had to be vacuum sealed. This product came with a card that if you wanted to return it, they would gladly assist you.They really did and I couldn’t be happier with Jamdok’s service. This mattress is comfortable to sleep on and the customer service is superb. It’s not often that customer service goes above and beyond from all Amazon purchases I’ve communicated with but Jamdok is surely A+!

Parfait pour le camping

Very comfortable as a topper! But it really doesn’t work as a mattress on its own.Love that it has a removable/washable cover. Unfortunately, the cover is not water-resistant so it doesn’t really protect the mattress inside.Once it’s out of its original packaging and fully inflated, it’s very difficult to roll it back up. Not as portable as it may seem.It’s an expensive product. Not sure it’s worth the price.
