Sei Mio The Bottom Line Under the Bed Restraints

Your bed doesn’t have to look like you get up to this! Sei Mio’s The Bottom Line can stay between you, your partner, and the mattress.

This under-mattress restraint set comes with plush wrist and ankle cuffs for getting tied down without adding permanent fixtures. Slide the straps beneath the mattress, fit the cuffs, and leave the next move to whoever’s still got their hands free.

Six D-rings give you different places to attach the cuffs, whether you want arms spread, ankles apart, or both. The webbing adjusts to fit most mattresses, including king and super king sizes. All that bed and nowhere you need to go.

The Bottom Line has nickel-free hardware, and the straps can stay hidden under the mattress between rounds. Pull the duvet over. Bed made.
