The KINGS25 code worked on the Serta Perfect Sleeper Elkins II 11" Plush Euro Top Queen Mattress. Subtotal went from $699.99 retail, to $349.99 sale to $262.49 with code. Add tax and free delivery and it felt pretty slick. They don't remove old mattress without the $99 upgraded delivery/set up option. I guess you can't win them all, thanks for the find!

This Promo code works on other sizes too. I used it on a full size. It added another $85 off.

Do you know the agent name that gave you the discount? Looking for the purchase and hoping the agent can price match also for me.
I'm not zdiddy but I just bought a BRS-900C and an agent named Odessa gave me a $37 discount on haul-away and set up, even though I just wanted the haul-away. Also discounted the matrress protector to $25. He said the code was "manager's discount". He couldn't stack coupons so the KING25 was used since it was bigger than his 10% off offer.

Any thoughts on the Serta Perfect Sleeper Elkins II 10" Firm Mattress? I purchased the BrentwoodHome Medium mattress from Costco a couple months ago but I am not liking it much. It is too soft. Considering switching to this mattress (the code does work).

Follow up question: any experiences of returning mattresses from Costco? Do they come pick it up? Thanks.
They'll either send a guy with a trailer to pick it up or tell you to donate/recycle and ask for a copy of the receipt.

Thanks OP, perfect timing. A little nervous about buying a mattress without testing it first, fingers crossed.

It's a $260 mattress, what could go wrong??

Quote from jday1529 :
I was planning on doing just this - buying two twin XL mattresses to replace my relatively new king - so my wife and I can have individual recline settings on our adjustable base. Is this something you regret?
The beds move around a lot. They sometimes create a gap between the beds that pillows or covers get lodged in, minor issues. I do feel that it has created a small rift in our bedroom life, as she has her bed and I have mine. I don't know. It is nice to never feel your spouse tossing and turning. There is no transfer of movement.

I thought I would go buy a new mattress once I got tired of this one, but there just isn't good deals on high quality single twin xls. So I'm stuck with a good memory foam bed, that my body is sick of.

Since I didn't have the PayPal offer, I ordered via chat and saved $50 on the delivery service. Still went through a cash back site, not sure that will work or not but it's fine if it doesn't. I think the deal I got on a king size mattress is good, and even though this isn' the best mattress out there, it's for my guest bedroom which is rarely used so it will be fine.

Thanks for the tip. I got shot down by a few agents using your strategy to get the $178 price, but then I said my friend got a deal with Delinah. I was transferred to her and was able to get the same deal. Thanks again!
