These are great tents. We love ours. Ended up putting two Exped magamat duos in it and I don't think I've ever slept so good in a tent. Good luck with the sale.
Replaced the tent mattress that came with our ikamper RTT with two megamat duos. They aren't cheap but they're super comfortable and well made. If you search hard enough you should be able to find them cheaper looking for coupon codes. We found ours for 20 and 30 percent off.
