Bassinet/cosleeper for tall bed

At the top of our mattress, our bed measures 28”. This is my third baby and I had a Simmons bassinet for my first, but the max weight is 15lb and the bassinet itself was very small. My baby grew out of it so fast. I went on to try the Arms Reach Cosleeper and it was alright but after awhile the mattress started to sag in the middle and I couldn’t keep it flat anymore so I don’t want to use it for safety reasons.

I really want a bassinet where it’s mattress/pad is the same height as my bed. Many I’m finding, the pad of the bassinet comes up to only 26”. An inch or so below is not a huge dealbreaker but from past experience I don’t want to do a lot of lifting and lowering from my bed in the middle of the night.

TIA!
