I am sadly parting with this wonderful bed because my husband and I upgraded to a queen size. It is a Tulo brand 10" soft mattress. It looks like they don't sell the exact same mattress anymore, but here's the website of the brand: https://thetulo.com/
The retail price for this fantastic bed was $650. It is very soft and comfortable! It feels just like it did when we first got it in fall 2020.
The bed frame is an IKEA Hauga frame in gray. It looks like it was discontinued because I can't find it on IKEA's official site, but here it is on a different website: https://www.aptdeco.com/product/ikea-hauga-bed-frame-full
The bed frame's retail price was $370. We got it about two years ago.
Both are in very good shape. We have used a mattress cover to go between the mattress & the fitted sheet the whole time we've had the mattress. No bugs!
Comforter not included. You can have the sheets if you want -- they are a high thread count, nice and soft -- but they've gotten a lot of sun damage over the years & are far from the crispy white they started at . . .
