My mom && I went to Sleepy's the other day, and we found amazing mattresses, but they be a bit pricey..
We've been doing renovations and are a bit tight on money.
So, any tips on getting them to maybe lower the price a bit. Or perchance a place that has cheaper mattresses?
Links would be great.

Thanks

Answers:    You can't find a good cheap one. Sorry.
Has anyone have a mat fitted lately, stair/lounge?
in fact, you can. Do you have a Beds for Less store near you? We enjoy one here, I got a queen size flippable set for $199.00. Free delivery & set up. It's not a pillow top, it's firm not complicated. I've had it for 4 yrs & it feels similar to new. Make sure you don't buy a one sided mattress. When that side wears out, it's trash. You can't turn it. If you don't hold this store, look at furniture liquidators. They sometimes have mismatched sets going for $99. a set & up.
