We have had the 3" version of this for years on top of a 1.5" piece of plywood. Will the 5" version be MORE or LESS firm than the 3"?

We are using the 5" and 3" in a trundle bed. It gives a firm very comfortable bed.

5 is more firm than 3 / From Serta mattress topper is very comfortable sleep to support back straight

Mine is very firm; I also have it on plywood. My 3 inch was soft and it bottomed out and the plywood was hard. I have the 3 inch on the 5 inch and it is soft yet supportive now.

Two 3" would probabaly work better than one 5.5" for an oblong tray. Be careful with placement so they are level.

Not sure about the 1.5 gap, but it could be raised by placing a piece of 3/4" wood under the unit, and that should make it work just fine. Hope this helps. Old Joe

I like mine. It is on the floor. If you had it on a box spring, it might have less support. So put it on 3/4 in plywood.

No, it is not as firm. I'd say it was firmer than the tiny mattress for the co-sleeper, by a lot.

i will say yes, because my desk is only about 3/4 inch and i have two of these on it firm as can be, but i would caution based on material of desk. mine is made of super sturdy hard wood. supports up to 500bls per square foot roughly, if it where ply wood or a cheaper material it might just break it.

My deck railing is 5 1/2" - it fits very tight and doesn't wiggle at all. My guess is you'd have to wedge something in to keep it stable for 3"...it's a great planter however - I'd give it a try

Yes, but it lifts a lot higher than 3.5 initially. Mines sitting at 5.0 inches, but im hoping it will come down when it breaks in.

I bought this mattress for my son who has a platform bed. The bed had wooden slats as the platform, which I didn't feel would be strong enough. We bought 3/4 inch plywood and laid it over the slats.works perfect.

It is no way near 1.5" thick. I would not want to lift it if that was true. Mine is right at 5/16" thick (0.3125").

Not quite 3/4" thick. It's a nice piece, but we've noticed that it wobbles a bit. I bought the board for my daughter, who loves to make pastry.

Mine is on a 3/4" shelf and it is fine. It is sturdier than a lot of these types of shelves and doesn't wobble like some of the cheaper ones do.

Hi, I would say it depends on how bad is your bed that you need to put this topper on it...mine bed was a pillow top bed, 2 yrs old that we hated sinking into...my husband had a depression from his body---the 2" layer helped very little to elevate our discomfort...I think the 3" would have been better for us...but instead I complained to Sleepy's and they took the mattress back and we got a nice normal mattress...no pillow top...just firm and perfect...I am not using the 2" topper I bought, I think I will cut it up and make dog beds out of it...good luck...

We bought the queen size version to put a sleep number bed on. Their plastic support structure sags. This platform is tall enough and stiff enough for the sleep number setup, which has a plastic plate under the air mattresses. Worst case for a mattress would be to a 1/4 to 1/2 inch thick sheet of plywood if the mattress settles in between the slats - or because the slats are a little lower than the frame. I found it easy to assemble and is very stiff - no sag side to side with the queen size.

I have it on a flat frame that I built, and it's just fine. The only thingI'd do differently is to get a thicker version - 6". Hope that helps.

I you cover it you may want thinner thickness, 5" is thick and firm, we used it for a mattress in the back seat of a truck

it really takes a bed frame to hold it securely and even then it will be slightly wobbly. It does work though attached to the bed frame. Don't think it will work with the plywood.
