Mattress topper - what thickness

I added a 3 inch foam topper to the queen minus 4 inches bed in the back of my rig. The old mattress was tough. With the topper on top of it I sleep like a baby now.

We use a 4 inch topper... Like sleeping on a cloud

I use a 3 inch on my cabover bed. It helps tremendously. A 4 inch would have taken too much of the already limited vertical space. I have a 2 inch for my occasional use jackknife sofa. Even it is bulkier than expected especially once rolled out for the first time-and rolled back up. It is bulky enough that I leave it at home unless I anticipate needing the bed.

Just check weights and rolled sizes and get the thickest (heaviest) you think you can deal with.

To each their own, but I used THIS ONE

It is 3 inches and is soft enough to make my NEW hard mattress a joy to sleep on, it also breathes well so it doesn't get hot.

I would not go any less than 3". I have a 4" topper on my queen bed and WOW do I sleep well!

We bought a little 2" topper from Walmart and it has worked out great! Makes the factory corner mattress super comfy.

I tried a 3 inch on the Jackknife couch, but found it too bulky to roll up. A 2 inch has worked fine for me for the last 2 years. I use a 3 inch on the dinette, which I keep down at all times and use large pillows to convert it to a couch for day use. 3 inch is definitely more comfortable (used one on the queen in my previous class A) but 2 inches is good enough. Tried a 1 1/2 one time; not much help.

We got the 2" memory foam topper from Costco, trimmed it to fit the 'queen' size bed, and it's now the best bed ever. Makes the original mattress 'sleepable'.

I have a sofa pull out...I first tried a 4"...could hardly lift it to store it. I then went to a 2" and still felt uncomfortable. Just bought a Craftsman 8" air mattress and pump...great comfort plus I just let out the air and fold it up! Highly recommend it for those of us who don't have permanent beds!

Oh, on my comment, full size air mattress.
