..prolly out west to you guys, Wisconsin or Michigan'ish...for half what SailRite is asking for what appears to be the same foam, DryFast name. Lots of support as new, no bottoming out. No measure yet on how it holds up over the years.
I've not carved them for cushions yet but after my back surgery last spring my spousal unit put both pieces of foam under my recuperative mattress to raise the bed and it was mighty comfy. I have two pieces about 31" wide, one is 6.5' long, the other is 7' long for just over 300 bucks shipped. Can't recall how much over 300 but not more than 350. SailRite wanted just about twice that.
